Previously using the Ultra-Xfinity 600 watt to power the gtx-260, well wrong idea as I started getting bsod and screen freeze in games. Called eVGA tech support who immediately recommends the Corsair like this one or comparable. I ordered this psu thru and the unit came a few days later. The installation went so smooth. This psu which has 140mm fan is much more quiet than the Ultra by a wide margin. As of yet no more bsod or freezes alike. I think my rig now has what it needs: POWER and much more power in reserve.

Excellent PSU

by smooney3 on 12/27/2008

I got this monster to power my upgrade from an 8800GT to a GTX260 (probably another for SLI in a month or so). It definitely has the juice to power that and much more. A single rail is definitely the way to go and with 60A, it should be able to handle whatever I can throw at it. It also looks pretty good in the case. I like the bottom mounted PSU in my case(NZXT Tempest), except that on this one it means that the sticker on the side is upside down. You can barely see it though, so no big deal. The neat little fake velvet bag that it came in, while completely useless, is a nice touch and makes you feel like you're getting a quality product. And speaking of which, this thing has some excellent build quality. It feels, looks, and performs nice and solid. Be sure you have plenty of room to stash the extra cables. They're a bit long (not a bad thing) and there are a lot of them (also not a bad thing). If you mount it on the bottom it also blows air into the case, rather than out, but I don't see that being a problem in my case. This is my first Corsair product. Judging from the quality of this PSU, I think I'll probably be a loyal Corsair customer from here on out.

Solid power supply

on 1/2/2009

I bought this to power my GTX 260 after I found out my old 500W couldn't handle it. It's a very good power supply, the rails are steady even after I overclocked my processor and GPU. Best of all, it has a nice five year warranty.
