I have a Rosewill RD400-2DB power supply (here's the specs: http://www.rosewill.com/products/781/productDetail.htm) and the Asus DirectCU GTX 460. The bottom line of the question is, I want to know if I could run this card off of this power supply. The rest of my system uses only about 125W. I know all the power fits (I have a Molex to 6-Pin for the missing 6-Pin from the PSU), and everything else is good (DVI on my monitor and the proper PCI-e 2.0). Just in case, here's the exact GPU: http://www.asus.com/Graphics_Cards/ENGTX460_DirectCU2DI1GD5/
If anyone can just give me a yes or no answer (and if no just give me a quick reason why), that'd be amazing.
Godspeed, Gentlefolk.
