Enermax Liberty 500W

[megatron]

I don't think the Liberty 620W can drive my system.:

Intell 955EE dual core processor
2x x1900xtx crossfire
4 x 512mb of OCZDDR2
1xdvdrw
1x300G harddrive
1xfloppy

So far I can run one card at a time but when I add both for crossfire, system will not boot...just turns on with no display.

I have the master in the BLUE and slave in the 2nd slot according to instructions and plugged in the extra molex connector on the motherboard and prescribed my Asus.

Oh yeah, motherboard in the Asus P5WD2E-Delux, bios 0403. I'll try again but it doesn't look good.

I got it to work!

So the Enermax 660 CAN run Intell 955EE with two x1900's folks

I have been building up a system based around an AMD Opteron 170 dual core processor. The current spec is in my signature, but I will be adding a Netcell Revolution 64 RAID card and three more Maxtor Diamond MAX 10 250 GB SATA HD's to it soon.

Anyway, I had what I thought was an excellent PSU (Vantec Stealth 470 W) for what I was running (but knew I needed more soon). Unfortunately, my system's OC stability was all over the map. One day I noticed that all my rails were underperforming at 2700 MHz stress test with dual Prime 95. The 12 V rail was the worst offender at 11.62V.

I went PSU shopping, and seriously considered three PSu's: The PC Power & Cooling 850W, the OCZ Powerstream 600W, and the new Silverstone Zeus 750W.

The PC Power & Cooling PSU's look great, and appear to be very well made. Certainly, the reviewers seem to like them. But to me, they seemed a bit overpriced, would have been a pain in the butt to order in, and lacked the modular cable design that I found so appealling.

The OCZ Powerstream 600W PSU looked promising, and most people I knew who had them were very happy. But I was put off by the glowing fans, and the lack of a modular cable design.

The new Silverstone Zeus 750 W PSU's specifications were very appealing. While it didn't have the modular cable system either, its extra power was very persuasive. If the Silverstone's release hadn't been put back until April, I would have likely ordered it, as I liked having another 130 W of power in reserve.

Ultimately, I purchased the new Enermax Liberty 600 W PSU (for $185.99 Canadian) and this is what I got:

My Mushkin Redline XP4000 1 GB modules suddenly became more overclockable (going from 255 to 262 MHz).

The length of time that my system was able to run a "stable" dual Prime 95 was suddenly increased. I am currently Dual Priming at 2650 MHz for nearly 13 hrs (going full 24 hrs). While I have run a higher overclock before, it almost always failed within first 2-3 hrs of dual Prime 95.

Once I get better cooling for my cpu, I believe I will be Dual Prime 95 stable @ 2750-2800 MHz range, and I am sure the new PSU will have something to do with getting me there.

According to Smart Guardian, my current voltages are:

CPU=1.29V (1.325 V in BIOS) ATX+12.0V=12.29V
LDT Bus=1.28V (1.30 V in BIOS) ATX +5.0V=5.06V
Chipset=1.53V ATX +3.3V=3.34V
DRAM=2.76V (2.77 in BIOS) VSB +5.0V=5.06V
VBAT +3.0V=3.08V

In the end, I gained a lot from the PSU upgrade, but the most important thing for me was piece of mind. I feel confident the new PSU will meet the needs of my system as it grows and evolves.

And if I ever DO feel the need for more power, my Silverstone Temjin T07 case has room in it for a 2nd PSU just like this one

I had a major failure in my system last week. It ruined two hard drives and my new power supply, with the reliability of the rest of my system now being uncertain. My new Enermax Liberty PSU seems to have been the culprit, although it could have been triggered by a power surge due to heavy fog and freezing temperatures.

Based on this experience, I would say going with one of these Liberty PSU's is a bit dicy, and would no longer recommend it. I am not condemning it yet, but certainly I had a bad experience

what happened exactly?

[Think]

Yeah, what happened?

WIth all the built in safety measures placed in this unit, it must of been a major shock to the system of some sort.:

Protected by OCP, OVP, UVP, OLP, SCP, OTP.

[kberguy1]

System seemed to work fine, until it got shut off. On reboot, I was having unexplained delays (4-5 x normal boot time). Finally, I went to reboot, and "disk failure" message + tiny curl of smoke appeared. Needless to say, I shut off immediately.

Was doing nothing that should have caused things to fail prematurely, Vcore only 1.333, etc. I never put more that 1.40 V through CPU, running wimpy video card right now, so no strain on anything.

Cannot explain failure, but...

the technician who worked on system said that it was the 4th Liberty PSU that he has seen cause problems, and that all seem to be over volting

I now have new OCZ Powerstream 600W PSU, and hope the reliability these products are know for will remain untarnished.

[Fhqwhgads6680]

Well... I just ordered my 500w liberty...I had only heard good things about these till I saw the latter part of this thread. I've used Enermax psu's for years and I have loved all of them so far. I will post my findings when it comes it but I hope I don't have the problems you had kberguy

[Think]

I thought I had powersupply issues with the unit as well but not because of the product but becuase of the system. So far so good, been running bench marks after bench marks with vcore, vdimm overclocked....both ATI's overclocked as well.

2x x1900xt crossfire
waterpump, 4 120mm fans
3 harddrives
2G of ram
intel 955EE overclocked to 4.6

I'm really making this powersupply work hard and I'm sure it's still not enough for my system but it's working..and working hard.

What i would like is a program to monitor how many amps are being drawn out while I run a 3d program. This way I can tell you for sure if the unit is work to it's rated potential

Any ideas on a program?

If u mean total amperage on the 115/230V, a program could only guess... I suggest the hard way (not the adjective hard).

Well I know that both GPUS are drawing out 20amps, the CPU about 10AMPS. I presume that the 75G x 2 Raptors shouldn't draw out more then 2amp at most, fans and pump are 2.5 amps, the cd...not even worth mentioning, the ram = 4 x 512DDR = not sure on that at all nor the motherboard itself.

Well I'm not sure exactly which program you would use to monitor pws fluctuations. How would you determine if instablility is coming from the powersupply unless it smokes and catches fire

12.15 and 5.13 volts are the 12v and 5v rails of my 500w liberty. Running 2 sataII HD, 1 DVD, x800 16pipes 550/550, opteron 2.7Ghz 1.6vcore (ad read from a digital multi-meter).

2.7 1.6v? ouch. My 170 does that on stock vcore

I did have it at 3Ghz with 1.625v but the fan was too noisy. I want complete silence. When I sort my eheim 1250 (gpu cooling only) out by suspending it, its going to be wicked quiet.

You may have 25% more performance but you spent 2x as much.

[nismoGT-R]

could someone tell me if it fits the P180 with a sli-dr expert?

[Starscream]

just got a 500watt liberty .

but to say stuff of value:
i saw a german webshop that sold seperate cables from Enermax for the liberty.

they cost some 4.90 (euros ofc)
3 difrent cables
1 has 2 SATA and 2 Molex (like the ones that come witht he PSU i gues)
1 has 3 Molex
1 has 3 SATA.

and cause of this link i think there are even more you can get.
http://www.enermax.com.tw/english/pr...il.asp?PrID=51


could be nice for the people that only got SATA HDs and could sue a cable with only SATA connectors.

[xerogenesis]

got one of these for free. like the sleeving job on the cables and the format of the modular connections , eventually traded it in for an antec truepower 550W EPS12V

[Entity_Razer]

Dual xeon rig running on it and I REALLY can't complain about these liberty's (500w) I've had mine for a good while now (half a year almost I reckon if not more...)

I OC my 9800XT to the max, my Xeons to the max and I have the 3HDD's and a DVD burner running along with a joystick in the USB port at any time

Thing works like a charm... but offcourse I wouldn't reccomend overloading the rig or running it on the edge of what it can handle.

BTW with all the protections on this thing I do wonder what caused the problems :s
this thing is more secure then fort knox

[megatron]

I have the P180 and an Epox 9NPAJ SLI

It fits fine:



I believe the stock cooler went a bit "pete tong", and became noisy so I removed the fan, stuck a tiny heatsink in the middle and directed a low voltage 80mm fan at it. Like some of the DFIs the chipset if right under the graphics card making it difficult to fit after market coolers.

Liberty 620W run good with my second SLI setup.... recomended

Good to know hausner, it seems Enermax has got a consistent success with the Libery Line.

Just a reminder, the Liberty 500 is at 99.99 right now at Newegg and a great deal.

got mine a while ago for 69 euro.

do think it was mislabeld as now it again costs 89 euro.
but anyway i saved 20 euro onit

[lross78550]

ive had some problems with enermax in the past either being doa or dying withing weeks of install but i have a liberty 620 and i must say im really impressed im running an fx-57 way overclocked 2 7900gtx's in sli a exos-2 water cooling system which pulls power from the main power supply and 2 wd 146gb raptors as well as a 200gb wd at regular 7200rpm. and the usual 2 dvd burners and normal bells and wistles and its been rock solid stable. the only thing im not running is a 300w light bulb known as a overclocked p4 prescot.

You're right...the only reason its still relatively expensive is because of te 22A dual rails.

im getting a liberty 620w for my setup, my antec 350 smartblue just cant handle it anymore, its damn hot and noisy, since I have a great load on it (prescott 3.6 + 3 hdds + 6800gt)
