I'm enterering into foldIng in a few weeks. I'll be getting two GTS450s and I'm just wondering what wattage psu I should get.
The rig will be a low end 775 dual core, 2gb of ram and an hdd. The CPU won't be overclocked or folded on.

I want to get a low wattage psu to save money, I was thinking that a 450w should be able to manage but I need some other opinions.

Quality 650W unit will do it.

450W is too low for two GPUs. Maaaybe 550W.

650w is a bit much..... I would err on the side of caution and try to get optimal efficency so I would get a 500w unit

You are looking at around 100w per overclocked GTS450: http://www.xbitlabs.com/articles/vid...0_4.html#sect0

220w on a i7 980x test system so a quality 450w should be enough: http://www.tomshardware.com/reviews/...0,2734-13.html

So, Quality 550W unit can do it?
