PCP&C Silencer 750w, is there a better PSU for $200?

[Oklahoma Wolf]

I bet Oklahoma Wolf knows.

Nope - I've never done business with PC P&C, and probably never will.

[syne_24]

You know about the only model I would get from PCP&C is the silencer 750 because it's actually not overpriced. If you have a Fry's in the area they are selling them for around $160. It's amazing that I can pick up 3x Silencer 750 and it still cost cheaper than the top PCP&C model. Seas M12 is a good psu as well, very solid regulation and quiet.

[epion2985]

I was of this opinion a while ago and after looking at whats on the market I still stand by it.

Zippy PSL-6850P (G1) 850W is the only PSU worth spending money on if you are going to spend more then $150 as everything in between is either of poor quality and questionable integrity or not as good of a bang(quality and capacity) for $.

As long as noise isn't a concern...

IIRC the M12 is actually single rail, the 'quad-rail' label is just for marketing. Ready jG's review for more info.

Read jonny's review, its dual rail, which is nice, but im still looking for just one nice big one...

Read next page.
http://jonnyguru.com/review_details....=13&page_num=3
I asked Seasonic about this "descrepency" and it was stated that the "deception" is really quite innocent. Apparently the initial design was for quad rails, and if rails did need to be split up into three or four rails, it would be easy to implement without completely redesigning the platform...
What Seasonic tells me is that there was an issue with high end video cards overloading a single 12V rail. So with Intel's blessing, Seasonic removed the OCP...

And those same wire groups with markings on PCB for two rails are there also in Silencer 750W. (not that it propably would be so silent, 80mm fans can't compete in airflow with 120mm fans without very high RPMs)

Sad part is (sad because most of us cant afford it) you can call PC&C or the likes and order a custom unit. Something I always wondered is how much would something like what I described above would cost.

Propably: "If you need to ask you can't afford it."

Zippy PSL-6850P (G1) 850W is the only PSU worth spending money on if you are going to spend more then $150 as everything in between is either of poor quality and questionable integrity or not as good of a bang(quality and capacity) for $.

Now if it's such ultimate quality PSU could you tell me why specified 3.3V and 5V max ripple values are higher than 50mV max specified in ATX specification?
Actually 12V output is low for its rating, only 60A.

[dave_graham]

lol

as a PC P&C reseller, i've gotta say, i love the units (i'm using a 610EPS and 750EPS personally) and my workstation builds are spec'd with the 750EPS (copper or black) as standard. PC P&C did away with the 850SSI (which i'm pissed about) and replaced it with the 1Kw-SR which is wicked expensive. huge 12v rail, but dear god....$$$

Where can i get the 850w G1?

[JPeitzman]

^^^ NCIX.com has the G1 version, but they are a Canadian website, I don't know if they would ship to the US. In the US you can really only find the non-G1 version. If you are not in the US I don't know for sure about availability. You could try browsing the FS/FT sections at XS or other forums. This is one listed at Jonny's forum (I hope I can say this, some forums prohibit against sending people to other forums), I think it is at $200, but it is not a G1. Otherwise you can get the non-G1 version here:

http://store.myaopen.com/psl6850p.html

in the US that is.

True the noise on the Zippy is a concern, but it is one of the best PSU's on the market. As for the OP, I would defiantly recommend the Silencer 750, it is a great PSU. Otherwise you could get something like a 750watt SilverStone Zeus, they are also great, Etasis OEM, rock solid and lots of power.

[syne_24]

it does look like a good psu as far as tight regulation but what's with the efficiency?

Efficiency 71%(200W), 76%(420W),71%(850W) at 110V 40℃

[Orbitech]

Thnx for the helpful thread Revv23

I 've been wondering what seems to be a more futureproof psu .. And I came to the conclusion that a strong single rail seems to be more futureproof. Imagine in a year from now a gpu that might need 20A on a rail, what would I do if I buy a psu that has 18A on a rail even if it is a 4 rail psu?
Also I have heard that you get less ripple effect with the single monster rails..

I'm seriously thinking of paying a premium right now to have piece of mind for a long time regarding my psu..(if you can say that with hardware components).

I was thinking that the Zippy PSL-6850P(G1) is probably the best I can get for a "logical" price.. 1KW PC P&C costs too much and I think it's price is vastly overrated in comparison to the Zippy 850W I mentioned..

Dunno I would like to hear your opinions regarding
1)the futureproof value of the strong single rail vs multiple rails
2)Zippy vs anything else in that price and performance area

Thnx in advance

Edit
p.s : As for someone who asked about the ripple values and general performance about the Zippy model I've heard that Zippy E macs have the tendency to underrate their values...In reality many reviewers of this product have been astonished by what this psu is capable of..

I also have a question.. Can somebody point me on where I can supply myself with one of these babies in Europe?

[epion2985]

As long as noise isn't a concern...

You can always swap the fan. The main job of a psu is to provide quality power, and if it does that well everything else is secondary, especially if it can be fixed.

Probably: "If you need to ask you can't afford it."


Now if it's such ultimate quality PSU could you tell me why specified 3.3V and 5V max ripple values are higher than 50mV max specified in ATX specification?
Actually 12V output is low for its rating, only 60A.

Not really, I was just poking fun, its fairly affordable, but then again thats relative.

Honestly I don't want to open my mouth because I am not really qualified to answer that, but I tend to trust educated people that I know for a fact know better then me. And it seems every qualified person (electrical eng. in line of work with psu, etc) raves about zippy and about a few of their psu's, the 850w one being one of them.

Maybe Oklahoma Wolf can shed some light on this.

PS:

Well there is something I also hear a lot, if it helps with your doubts:

Zippy tends to rate safe... it's hard to tell from the specs how good these things actually regulate.

There are ripple measurements of the 850W in here: http://www.jonnyguru.com/forums/showthread.php?t=88

Thank you for confirming that.
Do you by any chance know where can I buy the particular model in Europe?

[Oklahoma Wolf]

Not sure - you'd have to contact Zippy Europe to find out. There's one up for sale in the JG forums though if you don't mind getting the server model.

[Dumo]

Zippy info....Ask for Jessica....



Also http://stores.ebay.com/Madmouse-Discount-Computer-Parts

These guys selling Tyan server psu (pulled out from a system) which actually Zippy850W oem with Tyan brand (needs extension connector though)...For $180.

[Dumo]

I ran 8800GTX SLI oc'd to 670 core 1030 memory, X6800@4.4Ghz 1.75Vcore and almost all voltage maxed in bios. On benching load my Zippy 850W psu 12V line drop to 11.95V.
3 and 5V barely budge at all.

What are the differences of the gaming and server model?

Do you think that it's worth it to buy this one ?

[Oklahoma Wolf]

Gaming version has a black case, and I believe the fans are a bit tamer.

[Super Nade]

Cables are fully sleeved, Black case, quieter fans but similar/same innards as the PSL series. I sent Jon my unit and he reviewed it here:-

Some server models have two or more independently regulated 12V rails, while the gaming series are usually single 12V rail.

[LexDiamonds]

Just thought I'd add to this thread..

Like several others I decided the Silencer 750 was the best deal out there and I really liked the single 12v rail...

Unfortuantely I am having problems with TWO of them. Bought one from Newegg and long story short, it produces a very pronounced (and annoying) electrical whine under load. This only happens when a 3D load is applied (rthridbl and 3dm03 are the worst...there are practiaclly sound effects going on during 3dm03). Just running Orthos on C2D@3.85 its ok, but when I add the 8800 load into the mix its unbearable.

Contacted Newegg for RMA, ordered another one (I kept the original until next one arrived) Second one has same problem, if not worse.

I have tried everything from different wall outlets to disconnecting fans,pumps, etc. anything at all that might be generating EMI.

Called PCP&C and talked to tech. James who was very cool and understanding. He was familiar with 8800s, etc. He said they have sold 1000s and have had no reports of problems. The serial numbers on the two units I have are about 2500 apart so its hard to say this is just a fluke. He sugested I send it in to PCP&C to take a look at. I will most likely do that, but it has been frustrating so far.

On a positive note, the rails under load are rock steady and only the 12v rail budges by about .01v under load.

It looks like its the best psu out there right now for performance pc. It was posted on this forum somewhere that it held stable around 970w. And it doesn't cost $600 like the pc&c overpriced product. Its definitely a good investment as it will last for quite a while.

The G1 version is painted, quieter fan, sleeved cables and all the connectors you would possibly want.

Here is the G1 zippy page:

Don't know about Europe but you can buy it from Canada here:

Thnx for your info and links m8. I heard it is excellent at combined load too(3.3V and 5V and probably have more left for the 12V when compared even to SS 1KW which has 80A !!). Is this true? That is of major importance when running realistically a heavy system am I right?

[MrDeeds]

Hey MrDeeds, how did you get a black one, you just email them?

Sorry for the late response. I got my black silencer 750 direct by calling Pc P&C and speaking to someone in sales. It was the same price as other retailers at the time and I got it in a week.

Performance Pcs has started selling the black one also and they offer it fully sleeved for an extra $50(rapists).

I couldn't stand the copper one, it just wouldn't go well with an all black lian li.

[dave_graham]

fwiw, PC P&C does run out of the black ones constantly. i placed an order for several last week and they quoted me a week for receiving them AT THEIR FACTORY. just realize that they're definitely not always in stock.

[Super Nade]

I'm not sure why they started with the copper tones, it looks ghastly!
