That's right, it is loud when I compare it to my friend's Fanless power supply :D :D I just received my 510 SLI from PCP&C today, and man....this thing built like a tank, I have no idea why some people said this thing is loud!?! even under load the DFI Ultra-D chipset fan and the MSI 6600GT heatsink fan are much louder than the PCP&C, maybe they'd upgraded the fan or something but this thing can pull out good amount of air and it is quieter than my Aspire 520 and Antec Truepower 480. The BSOD at boot up on winxp is gone now so I'll see how far I can push the winnie and gskill LA, this beast rocks!!
:banana: :banana:

Now, I have a few questions, how far should I set the 12+ and 3.3+ rails? Is it ok to push them up to 12.29v and 3.40v? would these settings fried anything? I don't suppose I need to bump up the 5v (default 5.15v now)?


3000+ @2.66ghz 1.61v
GSKILL PC4800 512LA
2 DVD burner
2 raptors in Raid-0
MSI 6600 GT
EMU-0404 soundcard
PCI SATA Raid card
5 90mm case fans
(will add 4 more raptors soon)

thanks much! :toast:

Heh, good for ya. The volts you listed shouldn't do anything. In fact people have ran upwards of 4V on the 3.3V rail..

The only thing that has stopped me from ordering one of these was the concern over noise - I'm encouraged by your report. What kind of PS did you replace - watts, make, 20 pin? Also, did you order from PCP&C? I've heard that you can custom order units with quieter than normal fans. Thanks!

the newer version of the pc510dlx has a more pleasant sound than the old versions. The old ones whine and wail like a biatch. The newer ones i can sleep through at night.

Initially I had the Antec Truepower 480W PSU(20pin), winxp would crashed randomly, sometime I can't even boot up the system, then bought the Aspire 520W(20pin) to replace the Antec, I use the 20 to 24pin adapter and was hoping the higher 12v rail (35A) could combat the instability issues, and thought I could get away with a cheap PSU but I was wrong, with the Aspire I was still getting BSOD and random crashes.
Finally bite the bullet and bought this 510 SLI directly from PCP&C to replace the cheapo Aspire 520W, I wanted the Express version but they didn't have it in stock so the rep told me she would give me the SLI for the price of Express :D I didn't custom order or anything...just a regular SLI version, and this thing is quiet compare to the Antec and Aspire I had, even my video card and chipset fans are louder than the PCP&P, I know what is loud because I still have the 90MM Tornado laying around, loudness wise I would rate the Tornado 10 out of 10, this PCP&C is 2 out of 10. :toast:

$229 + $6.50 shipping from CA to VA. I probably could get away with the OCZ 520 or 600, but I hate the thoughts of "what if..."!! I think the PCP&C is a good investment, if I don't like it for whatever reason...PCP&C said they'll give me a full refund and they'll pay for the return shipping :D

Ya the OCZ units probably wold have done fine, but there is a reason the 510 is regarded as the best. How many failures have you heard about with a 510?? How many great results couldnt be more pleased with the 510 posts have you read??

I agree about the noise, Unless you have some alien super silent technology, your other fans will drown out the 510 easily.

When I saw the delta fan instead of the Nidec Beta SL, I was worried about noise, but it is quieter, and has a max speed of 55 CuFt/Min. So far, I've never gotten the fan to run full speed.

I've got several revisions of the 510, the latest is the quietest of the bunch and performance appears to be the same.

I have the 510 SLI and the 510 Deluxe. The Deluxe wouldn't go very high onthe rails, but the SLI models seem to be much better. I could go 3.5V+ on the 3.3V rail, 5.25V+ on the 5V rail, and 12.6V+ on the 12V rail. They're might be more still in those pots, but that's all I felt comfortable turning them up to.

Expensive? This is a bargain considering the costs of industrial SMPS. Most people dont think twice about spending 200 or more on a CPU or motherboard or RAM or hard drives or video card or speakers or cooling etc.... $200 is not outrageous considering the importance of the power supply and the effect it can have on reliability and overclocking. Why spend $100 on a power supply you'll have to throw out when you upgrade and then spend another $150 on a power supply you probably have to upgrade in a year or so. Spend $200 now and be set for just about anything that comes along this decade.

It's more expensive to to cheap out now and upgrade later and then upgrade later etc. than to save money a few weeks and have something that you'll have for 5 or more years.

To me, it's just common sense to just save up money and buy the good stuff first. Most people need instant gratification and just buy what they can afford that spurous moment. $200 aint bad considering what your getting.

If you run an older system that has no need for an ultra high output power supply (Very few systems actually do) , then you are better off buying something cheaper. It really doesn't make sense to use a nuclear reactor to power a flashlight does it? You'd be suprised about how much current your computer DOESN'T draw. Almost no single CPU computers suck up 510 watts of output. Even mine doesnt, I doubt any really do.

I totally agree to your meaning. That's also my point of view. But since I am a university student it's getting hard to afford stuff like that ;). For me my Enermax 550W must be sufficient atm.

Ya student life is a little hard money wise. I'd rather be spending money on partyin than a power supply if I was still in college. Actually I AM still in college, but It's a little different now days cause I have money for both :D. When I lived in the dorms, I got income by fixing people's broken computers and building cheap ones out of computers people were tossing out. I think if Microsoft ever found out what I used to do with my one license of XP, I'd be locked up right now :D . I've confirmed XP runs perfectly on a 200Mhz Pentium MMX OC'd to 230Mhz with a 145Watt PSU and 128MB 72pin EDO DRAM. Sold that Overclocked beast for a keg of Natural Light... Them were the days.

I have an Enermax 550 and it worked great for my computer until I reached almost 4.1Ghz on my old Northwood after about 15 minutes of prime95. Got the PCP&C 510 and I was 4.2Ghz 110% stable no matter what I had running for weeks on end. Currently, I run prime95 (GIMPS) in the background 24/7 while doing whatever and my 510 hasnt flinched with this 4.53Ghz Prescott.

I use my Enermax 550 on my 2.4Ghz Athlon XP Barton 2500+. Works absolutely flawless and quiet for that system.

It gets loud when the fan spins up to full speed. Usually after an hour or so of gaming on my FX55 / dual 6800GT rig it's very noticably loud (audible even above my vapo XEII on full pelt). It soon quietens down again though.

Actually, I bought a $30 antec sl350- 20 pin 350w psu. Modded the 4 pins in for the 24 pin on my DFI, and its handling a 2.6ghz a64, x700, hdd, cd, and 4 fans and still holding a 12.02v 12v line using my sperry digital multimeter.

I don't think the PCP&C 510 are expensive, it's not cheap by any mean but I think you get more than what you paid for it though. I have lots of friends wouldn't hesitate to drop $500 on a 6800 Ultra video card, $300 on a pair of memory sticks, and $1000 for the FX-55, but most of them are having a hard time to justify even a $150 PSU....I really don't get it. :confused: maybe it's a psychology thing and people often expected ALL PSU are suppose to be as cheap as some $40~$60 ATX case. :D

Video Card, CPU, and most Ram will get outdated in months, and their prices will dropped big time in about a year, but a good PSU will more than likely hold up its value for quite some time, and probably will out-last the rest of your equipments as well. ;)

People have to learn to build from the ground up. You have to have a solid foundation before you can expect a good build. I buy PCP&C because they have a 5 year warranty and are regarded as the best PSU money can buy. Hopefully with this SLI model I just bought, it'll be futureproof enough so that I can keep upgrading in the future and not have to worry about power.

That's the way it is :). I prefer spending my money for parties so my computer get's not the attention as some time ago. When I made my entrance qualification for university I had the time to work nearly every afternoon at a computer shop. Great time. Always party and a nice, up to date rig. Fortunately I learned much about computers in that time so that I can administrate the computer networks of some local companies now. I hope to finish in summer 2006 :-D.

What is the point of turning up the rails? I mean don't all the components downregulate anyway?

Yup just about every critical component is fed by another DC-DC converter that puts the voltage down several volts. I personally have gained nothing from running a tiny bit of extra volts, but the benefit are that the power supply can only put out a certaqin amount of current, if you boost voltage a tad, you can gain a bit of extra power because volts time current equals power. If your device needs 10 watts of power from the DC-DC converter, feeding the DC-DC converter a higher voltage will make less current flow from the power supply. Like with CPU's, the DC-DC converter here takes in 12 volts with medium current (10 amps) and outputs 1.XX volts with ultra high current (80amps). The device your powering is a constant power load so if you increase volts, current will decrease in order to deliver the same amount of power, Current ability is the limiting factor in Power supply design, if you can make it deliver less current, but the same amount of power, you gain efficiency and reliability and a little bit of headroom.

The reasoning for increasing Primary power supply volts is the same as the reason automanufacturers are giong to a 48 volt electrical system. More volts equals less current for the same power output. High current circuits are the least efficient. Working with higher voltages makes it possible to gain lots of efficiency. With high current, circuit board traces act as resistors, this is less of an issue with high voltage.

I doubt most people know that this is the REAL reasoning, I think most people believe that increasing PSU voltage is like increasing CPU voltage, which it is absolutely nothing like. Increasing CPU voltage increases CMOS signal quality, Increasing PSU voltage is done to lower output current. When your PSU is running near its limits, it can help to stabilize your system, but it never gains you massive overclocking, contrary to popular belief.

SPL15: Thanks for the explanation.

Essentially it boils down to: If your PSU is maxed to the limit raising voltages on all the rails might help increase stability, no?

DVD/CD and HD don't use DC-DC converters on their circuitry, correct? So isn't it possible to fry you disk drives if you up the 5.0v? (the 12v is used just for the motor, isn't it?)

Can you tell where did you draw the 4 additional pins from?

On the topic: the older PCP&C's are indeed loud, I consider my vanilla 510W loud even when I replaced the PSU fan with a low speed Panaflo 80mm one. The airflow through all the bunch of components inside the PSU somehow makes it to whine a little.

Well overvolting the 3.3V rail is useful when your VDimm runs off of it and you want to go above and beyond 3.2V. Of course now with the new DFI NF4 boards you can draw VDimm voltage from the 5V rail so it is not a problem. Also, when doing some extreme overclocking, overvoltage on the rails helps with stability.

My Enermax offers auxiliary power connectors with 5V, 3.3V and 12V and I made this adapter (http://www.xtremesystems.org/forums/showthread.php?t=53557) to connect them to my DFI. The additional rails increase the wire diameter leading to a lower resistance and power loss. I don't know if it really gives you a noticeable advantage but I had the parts on my desk ;).

DVD/CD and HD use something called an H-Bridge to drive their motors, they do not run directly off of the 12v line. If they did, your HD platters and CD/DVD's would spin at a RPM dependant on the 12V rail which would definitely cause issues with corrupt data.

The electronics on some older HD and CDplayers did run off of the direct input, I'm not too sure about today's equipment. I have heard reports on people frying their Peripherals by increased rail voltages though. The PCI slots have several direct outputs of the rails so this is definitely possible. Computer peripheral manufacturers really dont care about if their equipment runs at out of tolerance voltages. They design euipment to run within the specification, if their device dies of overvoltage from the PSU, they are not liable for the repair. Over 95% of their sales are to normal people who use computers in a normal way. If they have .05% of their product output die from overvoltage by OCers, they will save thousands of $ compared to having to overbuild their product for the relatively few people who run stupidly high voltages.

Standard industry practice is to design products that are capable of running 120% higher than what it is rated. Any decently made device should be able to handle 10% over spec whether it be voltage, load, temp, clock, etc. But caution must be used because I'm noticing an obvious trend of companies tightening up this tolerance in order to save costs. Its cheaper to design/build products that are capable of only 5% over spec than to design/build a product that is capable of 20%.

Example: A computer PSU that needs to put out a real world 350 watts. It's more expensive to design a supply capable of 420 watts and run it at 80% of it's max than to design a PSU capable of 365 watts and run it at 95% of it's max design capability. They both run the same spec, but one is a whole lot less expensive to make.

One thing to note is that power supply design right now in the top of the line stuff is limited by heat output in the given size (Called power density). In order to be able to put out lots of power, the supply must be able to get rid of the heat caused by the 20-30% of inefficiency of the supply. If your PSU claims an output of 600 watts, it must be able to dissipate the 120 to 180 watts of heat the PSU produces itself. Silent fans are not that great for moving hot air. Think of Your CPU. A CPU that dissipates 120-180 watts needs lots of air flow and Heatsink surface area to dissipate the heat. The heat dissipative surface area and air movement through a typical power supply is tiny compared to most CPU's that have far less than 120 watts of heat output. To me, the "loud" fan on the power supply is music to my ears cause it shows that the PSU manufacturer knows this information and would rather have a product that performs instead of looking cute. I'm not a cute type of guy, I like raw performance over cuteness.

I find it funny how people B&C (Bch & Complain) about the noise of their PSU fan when they have four 120mm Vantec Tornados on their radiator and 8 case fans. You can get a lot more stable power out of a PSU safely just by keeping it cooler. I get lots of PM's about what i did to my PCP&C 510, but By looking at typical derating charts for Industrial SMPS's, adding a high CFM fan is THE most performance improving mod you can possibly do to improve your PSU performance.

Took my DFI Sata adaptor, cut the Sata end off, took the 5v and 12v and ground from that, and the 3.3v line from the old AT connector on this thing, into a 4 pin molex cut from a dead psu.

When doing that modification, you may have issues with some power supplies because of the multiple 12V rails. Although they are supposed to be exactly the same, they are usually off from one another by several tenths of a volt which can cause lots of current to flow from one rail to the other if wired in parallel and can cause problems with regulator stability. The outputs may oscillate if the regulation circuitry becomes unstable and will eventually kill the supply.

Make sure if you do this mod, to check to make sure that the extra lines you are using are on the same 12V rail as the one going to the motherboard on the regular ATX connector. A simple ohm's resistance check is sufficient (with the power off :eek: !!)

Switch-Mode Power Supplies dont like to be paralleled unless they are specifically made to do so. Some handle it better than others, but still not recommended.

That's true, but I never thought that PSU's have seperated rails because all PSU's I've opened so far distribute their power only from one point and rail per voltage. Well ok, I have to admit that most of them were cheap ones ;).

Low power and cheap PSU's will usually only have one 12v rail. ATX 2.x spec says that there must be 2 rails and I think it says one must be used exclusively for the MoBo and the other is for peripheral devices. UL requirements state that no more than XXX amount of VA's per rail so if the you need more than XXX amount of VA's then you must split the power between multiple rails.

PCP&C 510 has dual 17 amp rails and the 850 has four 17A rails.

ROFL! I hope you don't like your women like you like your PSU's!!!

Anyway I agree with you on the noise level of a psu. I could care less how loud it is, if it is in my main rig. I usually have headphones on anyway, plus performance is definatley key.

Although, I mildly disagree with "THE most performance improving mod" of yours. I am not saying it isn't effective, but for most people out there, they tend ot have their PSU in the Hottest part of their case. Obviously this really doesn't apply to serious becnhers and the like, but i have noticed a HUGE decrease in temp readings of the exhaust of my PSU's when I have them in one of my inverted cases, like my PC-V2100. Essentially, a PSU shouldn't be in the top of a case if you want to get max efficiency, IMO. PLus it is a FREE mod and takes ZERO skill, plus you don't ruin your warranty...

Anyway, after readin this thread and a few others I have decided to give PC Power and Cooling another shot. I ordered a 510 SLI yesterday.

I had a quasi-bad experience with my previous Turbo Cool 510 (it is one of the EPS12V versions). Anyway the PSU has NO problems running my P4 865 machine, but I was getting voltage spikes and sags across all the rails on my a8n-sli, which caused random reboots, and shutdowns (before this I had never had a PSU turn off by itself). Oddly enough my thermaltake 480w ran the a8n-sli with out any hiccups. All this testing was done with one 6800GT at the time, I highly doubt the TT PSU could supply enough for both 6800GTs, with a measly 18amp on the 12v.

Anyway , the older 510 turbo cool wasn't super loud either, but definatley louder than my 400w Zippy...

ROFL! I hope you don't like your women like you like your PSU's!!!

Anyway I agree with you on the noise level of a psu. I could care less how loud it is, if it is in my main rig. I usually have headphones on anyway, plus performance is definatley key.

Although, I mildly disagree with "THE most performance improving mod" of yours. I am not saying it isn't effective, but for most people out there, they tend ot have their PSU in the Hottest part of their case.

My philosophy on electronics for sure does not apply to woman!!! I like expensive electronics, I dont like expensive woman. I Like plain classy looks with electronics, but my friends say the girls I date look like strippers (Only two actually were). I'll save my pennies to buy the best of the best in electronics, If I ever have to buy a woman in my life, I'll shoot myself. I like to tweak and do modifications to electronics, but as you are well aware, you can't change a woman no way no how. I like to mess around with my test equipment on electronics, but I think my girl would find that a little too kinky.

Your PSU mod basicly does the same thing the higher CFM fan does. My main point was to say that keeping your PSU cooler will be the most performance improving thing you can possibly do to a power supply at it's limits.

I've watched the rails on my 510 and there is nothing abnormal in noise/spikes coming for it. Switch-Mode power supplies in general are not the cleanest power supplies to begin with. Noise is really the main drawback of a SMPS so it is to be expected, 80-100mV peak to peak is about as good as it gets, this equates to about 10-20mV RMS real world. Most ratings you see for ripple are RMS. ATX spec says no more than 50mv RMS I believe. I've had in-experianced technicians see a SMPS noise wave for the first time flip out because it is so erratic and assume there must be a problem, but in reality it is perfectly fine, they just dont know what they are looking at. If you dont know what to look for in a waveform and aren't measuring it correctly, the information on the Scope screen is worthless.

Tell us how you like the SLI, I'm sure others would like to here first hand experiances instead of my outbursts of information.

Also, whining from a power supply fan wont bother me, but whining from my girlfriend will drive me crazy!!!

I don't generally have much fan noise in the room, but I have not heard a peep out of my 510 SLI. Best $240 I ever spent.

And yes, more power does require cooling, some don't seem to understand that :rolleyes:

I Love my PCP&C 510deluxe, though i did mod the front w/ a thermalake butterfly blower, so the back fan never really turns up, rock solid +12v@12.224 outta the box I LUV IT!! just like matt9669 said its definately the best 200$ iv'e spent on my PC to date!!!!

Good to see your happy with your PC P&C SLI psu. Im going to upgrade this PC P&C 510w DLX for the SLI version I think.

That's right, it is loud when I compare it to my friend's Fanless power supply :D :D I just received my 510 SLI from PCP&C today, and man....this thing built like a tank, I have no idea why some people said this thing is loud!?! even under load the DFI Ultra-D chipset fan and the MSI 6600GT heatsink fan are much louder than the PCP&C, maybe they'd upgraded the fan or something but this thing can pull out good amount of air and it is quieter than my Aspire 520 and Antec Truepower 480. The BSOD at boot up on winxp is gone now so I'll see how far I can push the winnie and gskill LA, this beast rocks!!
:banana: :banana:

Now, I have a few questions, how far should I set the 12+ and 3.3+ rails? Is it ok to push them up to 12.29v and 3.40v? would these settings fried anything? I don't suppose I need to bump up the 5v (default 5.15v now)?


3000+ @2.66ghz 1.61v
GSKILL PC4800 512LA
2 DVD burner
2 raptors in Raid-0
MSI 6600 GT
EMU-0404 soundcard
PCI SATA Raid card
5 90mm case fans
(will add 4 more raptors soon)

thanks much! :toast:I got my SLI version to day and I can't hear any difference as compared to the old vanilla version I have - still 30-44dB. Which BTW corresponds well to the spec's on PCP&C's HP. No difference what so ever, and I'm surely going to modd this one too with a temperature regulated max. 26dB Papst fan.

I got my 510 SLI, just last friday and I am definatley pleased with it. Honestly, I can't even freaking hear the fan over the rest of my machine.

It improved my 6800GT's overclocks and stability GREATLY. I used to have all sorts of stability problems when I overclocked my gt's now, I can push them to the limit and I will get artifacts but I have still been unable to crash to desktop. @ 425 1170 for both.

The Inverse Law Of Desirability PSU vs Women:

You want exactly the opposite in both.

Except, I dunno man, if you have had two strippers as g/f and you didn't have to "pay" for them, in one way or another, I would be SHOCKED! (pardon the quasi-pun)

Actually, I bought a $30 antec sl350- 20 pin 350w psu. Modded the 4 pins in for the 24 pin on my DFI, and its handling a 2.6ghz a64, x700, hdd, cd, and 4 fans and still holding a 12.02v 12v line using my sperry digital multimeter.

Who needs a pcp&c? :toast:

Me. Try running my rig with that little wimpy antec :)

No they both were girls I met at a bars at University of Michigan and they seamed halfway normal. After I found out what they did for a living (working at Deja Vu), I kinda severed the ties before my friends found out they really were strippers.... That's all I need. Important business clients finding out I hang around with strippers from Deja Vu...

I finally got my 510 to go to full speed fan today. I turned off the intake and exaust fans on my case covered all the openings and played counterstrike source for 30 minutes. Temps in my case rose to 44 Celcius and my PC locked up (Northbridge and memory were HOT :eek: !!). The delta fan on the 510 when full blast is definitely not quiet, but still quieter than when I have my case fans on.

just cuz it burst into flames doesn't mean it cant handle it ;) Not enough molexs? make an adaptor.. I bet this psu would run your system for atleast a little while. It was runnign a 3ghz AXP. :D

Hmm.. I have 4 90mm fans, and a 90mm tornado... and people complain of a loud PSU? :eek:


lol.
