5 out of 5 eggsGood Enough

Pros: Replaced an old C***USA 350W PSU. Works like a charm

Cons: None

Other Thoughts: What can you say about a PSU that works? It's very quiet and does its job. Wish my employees were like this....

2 out of 5 eggsDidnt live up to expectations

Pros: Not too sure

Cons: Wasn't able to power my x1950gt without freezing or locking up. I know it was the PSU because when I used a stronger one, the problems went away.

Other Thoughts: Newegg, what can I say other than they're the best - dont even think about shopping anywhere else.

1 out of 5 eggsI've heard good things just not in my case

Pros: I've heard only positive things about this product and even though mine never worked I still recommend it.

Cons: ..It not working kinda is a con :)

Other Thoughts: If you want a sure thing I wouldn't suggest it, but for the money its the best.

5 out of 5 eggs

Pros: Quiet, reliable. More than enough plugs for anything. Inexpensive. For what it is, it's a very good buy.

Cons: A big tangle of wires from this thing, pick up a couple of zip ties to keep things from going everywhere. Also, it really doesn't allow for much more powerful expansion.

Other Thoughts: Powers a cheap build computer for my mother, which was a no frills build. If your computer has a bit of ooph, I'd suggest something a little beefier, but if it's baseline components to surf the web and read email, this will surely power it.

5 out of 5 eggsA great find

Pros: The big unexpected plus as I see it is that this supply seems quiet to me. It has the best specs of any 400W supply I looked at and appears to back it up, I tend to trust specs on supplies made for OEMs, they don't go for the retail marketing glitz.

Cons: As other have mentioned the power cables are not long, in larger cases you'll need Y cables. I think the money saved here could buy many of those (: Also, note that the 2nd 12V supply rail is dedicated to the 12V ATX 4 pin connector, which seems perfect for my application; one rail drives the processor, the other the drives and video. No PCIE connector for video.

Other Thoughts: Thanks to other reviews for convincing me this was worth trying.
This supply is running a E4300 @3Ghz with 8800GTS video just fine, no sweat. Thanks to Newegg for carrying great stuff !

Pros: nada

Cons: DOA

Other Thoughts: Newegg is great with RMA's. Don't be afraid to order from them. I've been with them for years now. Built many systems.

5 out of 5 eggsEver overclock a psu?

Pros: Exceeds 400 watt specs! Tested on Futurmark 06 benchmark and STALKER game for several hours. Maintained past spec loads of 400 watts, handled 450 easily and even peaked to 492 watts without shutting off on gaming. Stays fairly cool. Under my extreme loads the psu only stayed warm. Stable Stable Stable. This psu is not meant to run a machine like mine. I'm seriously going to make this an OEM PSU for personal builds. Just look at the system I tested it on!
Watt meter used was Seasonic Power Angel. This psu WILL deliver more than 400 continous Watts. Newegg is Amazing! They deserve to make good money. Never had a bad experience with then.

Cons: Negligable...Only because I'm overclocking, 3dmark06 was the only test that could shut this psu down and only 15% of the time. This psu is SICK! I can not believe that a 400 watt psu could handle my system and maintain nominal loads for 465 watts for a nice hour of gaming/benching. I had no problem at all running my Opty 170/SLI stock. It will power it w/o any issues.

Other Thoughts: PSU was tested on my same system, using 2 differnet processors:

AMD 3200 Oc'd to 2.6 ghz
Opteron 170 dual core at 2980 mhz
DFI Lanparty UltraD (SLI mod)
2 x Evga 7900GT's (both volt modded to 1.55v (725/800)
2 x Maxtor Sata drives in RAID
CPU + both GPU's watercooled while psu supplying pump power.
Scythe Icute VFD fan controller manipulating 3 YL fans on radiator.
1 x large 120x38mm Sanyo Denki Exhaust fan

I bought this as a replacement psu for a friends emachine and matched it with a Biostar T-force 6100 mb from here (open box). I wanted to see if this psu could truely handle extreme loads. My system normally pull 400-500 watts while gaming on my Enermax Liberty 500 (bought from here too!). This psu is rated 400 watts max and initally I had trouble with my mid overclocks around 2.6ghz but I think it was a bios setting. I finally was able to get all 2 games tested stable at my maximum system overclock 2.9ghz, opty 170, and sli 7900gt's vmodded to run 720+. Amazing PSU!

4 out of 5 eggsGreat PSU w/ a couple shortcomings

Pros: Stable, Quiet, Quality. 2 Separate 12V rails! This is my go-to PSU for builds.

Cons: Cables are shorter than some other PSU's in this class. Won't be a problem unless you have a case with a non-standard layout. A little skimpy with the amount of connectors.

Other Thoughts: Powers: Athlon X2 3800, 7600GT, 320GB WD HDD, DFI UltraII M2 with room to spare. I built in an Antec P180B and had to get extenders for the 20+4 and 4-pin ATX power blocks. Just so you know if you're using a case with the PSU mounted at the bottom.

5 out of 5 eggsGreat, satisfied me

Pros: Powers all my parts with plenty to spare.

Cons: Not enough 4-pins. Not really a con...

Other Thoughts: If you don't have a power hungry graphics card this PSU is the way to go!
