Quick question I am hoping someone with experience can help out. I have in my system now a single MSI N460GTX OC 1gb card. I just picked an additonal one up used from ebay for $100. I also just buoght three brand new monitors. My intention is to add the second card in SLI and run NV Surround with the three monitors.
Yes, a Corsair 620HX will handle those GPUs without a problem. http://www.guru3d.com/article/geforce-gtx-460-sli-revie... Guru3D found that a GTX 460 SLI system pulled 435 watts from the wall AT PEAK. They used Furmark, a program which is designed to push the GPU beyond reasonable limits. I doubt you'd see your entire system rise above 400w.
Well, there's your answer. I won't ramble on Cheers!
