680w PSU for $25 :pfff: 

that PSU does one thing well, act as a paperweight. if you even pushed it past 300w, you would get a spark show. i would never purchase anything off geeks.com, most of their crap is refurbished sold as new. even if the items where new, they are still junk. a solid 650w PSU will start at $80 out the door (ocz ZS, antec EW or rosewill hive) with better units costing even more. what kind of performance would you expect from a no-name $25 680w unit? see the link to find out

To be honest, I ordered a lot of things from them, including that PSU I just posted new about 3 years ago, the thing is still going strong running 6770's and an old Phenom quad 3.8ghz. I do agree its cheap, Sometimes I like to take a gamble. Only thing when I look at when I buy off band PSU's is the amps on the 12v rail, if its decent then I might just get it. Personally I will choose Corsair or OCZ or any of the good 1s.

Btw that link doesn't prove anything, You gonna have failures with any PSU. Corsair is more reliable I do agree.

it actually proves a lot. with a quality PSU, its safety circuitry will kick in and shut down the PSU when problems arise. a quality PSU will also deliver 100% of its rated power. with a cheap PSU, you get a spark show at under 100% load and it lacks any safety circuitry allowing it to take out other PC hardware as the PSU goes.

NONONONONONONONONONONONONONONO!!!!!
(sorry moderators)

I was GIVEN one of those PSU's, and let me say I've had my share of Thermaltake TR2's and Dynex power supplies, and this thing is in a tier of its own. It is quite simply the worst power supply I have ever seen. Even compared to my Dynex, it weighs half as much, is physically smaller, and just feels like it has poor quality.

I know asthetics is no way to judge, but the power supply also has half the connectors of my Dynex 520W. That alone is a signal of a bad power supply. It has 1-six pin, while even the Dynex has 2.

It is quite simply, the most miserable power supply ever made. Right now, literally, it is being used as a paperweight I think, unless I stored it in the Dell Dimension 1100 that is sitting in a closet somewhere. I forgot where it is.

DO NOT BUY!

I have been trying to figure out how to get rid of it. I thought of cutting off all the wires and opening it up and displaying it, maybe a cool display piece. I dunno. Just dont buy it. It is awful. I would expect it to deliver about maybe a little under 400W of its rated power. It has 2 12V rails at 20A each, which is absolutely miserable for a 680W. My Antec High Current Gamer 620W puts out 48A on the 12V rail.

Read this. Apparently the 12V2 rail isnt even connected to the power supply!
