im about to build a new system but im not sure which corsair psu to choose between 620w, 750w or 850w
but most likely, this will be the parts for now and i'll be completing all the fans of the antec 902 case while planning to sli my gpu in the near future..
cpu intel i7-920, 2.66ghz
mobo asus P6T DELUXE
gpu GTX 260 sp 216
DDR3 Corsair dominator ,TR3X6G1600C8D,88820
hd 500gig SEAGATE 16MBcache ST3500418AS
dvdRW samsung sh-s223
CASE ANTEC 902
LCD SAMSUNG 23" (P2370G)
will a 620w psu work? or do i need more than that to supply the 2 gpu in the future considering a lot of fans installed in the antec case?
That would be pushing it. The 620HX only has two PCI-E power connectors, so you would need to use adapters. I certainly wouldn't use a 620W PSU to power that system with SLI GTX 260 GPU's. The way I see it, if Corsair thought it could power a system that required four PCI-E power connectors they would have given it four PCI-E power connectors.
