The Epower, as one would expect given that it's twice the price. Price/Performance wise, I'd still prefer the XClio I linked to earlier. More than sufficient for a 7600GS/GT, well priced, and reliable.So I've been searching for the PSUs and I chose following two
LOGISYS Computer PS575XBK ATX12V 575W Power Supply 100-120V/ 200-240V cUL, FCC, CB, CE, CSA - Retail

or
ePOWER ZU-550W ATX12V Version 2.0 / EPS12V 550W Power Supply 115/230 V UL, CE, FCC, TUV - Retail
http://www.newegg.com/Product/Product.aspx?Item=N82E16817101021
Can someone suggest me which one is better?

ePower is Topower's retail branch. They used to be very good, but the more recent units have been exhibiting poor voltage regulation. Still better than a lot of the junk out there, though.
....the choices are due to the fact that I can't spend more than $70 on PSUs....
Solytech OEM - Basically highend Deer. I'd avoid.
A very solid unit, one of the best for its price.
Ultra is discontinuing the X-Finity lineup. As a result, these units can often be found at great prices. Definitely solid units with a flashy exterior, if that's what you're after.
Retail Raidmax's are a lot better than the OEM units that often give them a bad name. Even so, I'd pass. There's better for the money.
I'd be spending my $70 on an Enhance ENP-5150GH. A rock solid, high efficiency unit.but don't be angry at me
Older or newer?
Topower makes all Tagan units as well as some units for a host of other companies, including BFG, Mushkin, Hipro, older OCZ, Spire, Vantec, Scythe and others. The voltage regulation problem has been a commonality between all of their newer midrange units.
Please note the updated "good" and "ffooooo bar" lists.
Got a deal on some Antecs about 2 week ago, bought 15 EA 500 for 49.99 each, there only 17A on the 1&2 12V and alittle low on the 5.5 but I think they retail 85 to 90 bucks. Used 3 so far and all good, I would not use them for a big SLI and X harddrives setup but they seem to do pretty good with a general setup. Im running a Enermax Noisetaker 600w in mine right now, had so many case fans was tring to find alittle less noisier P/S. Kinda freaked me out about 3 days after I had it, I went to boot up and (nothing)
! unpluged it hit the power button a few times, plugged it back up and its been fine ever since
Nothing like working overtime on psu comparison revsions.
Good:
Antec(except Smart Power models) - Astec - AOpen - Channel Well - Coolermaster - Enermax(except Liberty models)
- Enlight - Fortron Source (Sparkle) - HEC - OCZ Technology - PC Power & Cooling - PowerMan
- Seasonic - SilverStone - Sunbeam - Tagan(older models) - TTGI/SuperFlower - Vantec - Zippy / Emacs - Verax - XCLIO - Zalman
- Corsair
Bad:
Allied - Antec Smart Power models seem to lack(recommend True Power or NeoHE) - Aspire - CoolMax - DEER - Enermax Liberty models - ePower - EYE-T
- KingStar - L&C - Linkworld - Logisys - PowerMagic - PowerUp - Powmax - Q-Tec - Raidmax - Skyhawk - Star
- Turbolink - Ultra - ThermalTake(complaints heard some good some ???) - Rosewill - SilenX ??? ToPower(newer models)
The one that fits onto the "good" list as well as being a good work horse supply here can be seen at http://www.antec.com/us/productDetails.php?ProdID=22480 That includes running three hard drives along with two burners, video capturing/editing, multimedia, and even gaming including an occasional oc.
Not all Hipro. Anything Hipro with a TOP prefix in the name is Topower. As for Mushkins, the highend units are based on a different platform, the midrange units don't do so well: http://www.jonnyguru.com/review_details.php?id=31
Yeah, they don't fail to often at least. To give you an idea of what I mean, take a look at this review of a BFG 650W. It's got the same guts as the ePower 650W.As fas as ePower its been about 3 months since I install one. I guess I have installed about 12 of them and none DOA and only one has come back, pretty good streak
Nice find. There's no OCP on either rail, so you shouldn't run into any power distribution problems. It's essentially a single rail unit, as is pretty much anything built by Seasonic. I wouldn't worry so much about the 5V rail either. Given how little it's being used these days, I can't see it being the limiting factor unless you're using it on an old Socket A system, or one with a whole lot of hard drives.
Coolermaster are one of those companies whose PSUs are made by a whole host of different manufacturers. The Extreme Power 430W units are Hipro built, not too bad for the money. The lower end Real Powers are Acbel and don't perform too badly. The Extrem Power 600W is a rebadged Seventeam 500W unit. Solid up to 500W, but that's all. The newer Real Powers of 850W and above are Enhance built, and perform very well. Which units have you had trouble with?
I tried to do something like that a while back, and it became unmanageable. I still intend to make something a little more comprehensive, but don't have the time at the moment. Perhaps leave anything 'middle ground' off and restrict it to known good and known bad (and even when doing so it's not really fair to bundle some of those Antecs, Enermaxes, Ultras, Thermaltakes, SilenX, Topower, etc... with the likes of Powmax, Deer, L&C, etc.... There are very significant quality differences there).
