I'd like to know if the Sesonic X750 can power 2 GTX 480's in Sli. I just bought the psu so if not this sli venture will have to be put on hold because I'm not buying another psu in the near future. Specs are:

Core i5 2500k
Asus P8Z68-V Pro
Corsair H100
16gb Corsair Vengeance DDR3 @1600
Seasonic X750
Liteon DVD-RW
ASUS VS248H-P Black 24" 2ms HDMI LED Backlight monitors X 2
Logitech G-15 keyboard
Razer Boomslang CE
TP-Link wireless USB 2.0 adapter
Samsung Spinpoint 1tb HDD

it can probably do it because its an excellent PSU and you can push it above 750w but it's one of those scenarios where just because you can do it doesn't mean you should. you would really be pushing that PSU. sell your GTX480 for a GTX580 or GTX590 if you really want more single card performance (or SLI less power hungry cards).

You said you just bought the psu , when and where , if you can return it for a larger one then you should if you really want to do SLI.

I have been looking at the GTX 580 to replace the GTX 480 but might wait a while seeing as the 480 is new too and maybe I can find a deal good deal on a 580. The 590 is unrealistically priced for me at the moment. Time to start saving I guess.

If you want to objectively, accurately and scientifically determine what PSU power is required for your Vid card and PC in both watts and 12v rail amps., the forum Utility link below will show you how easy it is to calculate this information and objectively determine which PSUs are quality built, reliable PSUs that can meet your needs. Be advised that the available 12v rail amps. is just as important as the total PSU wattage. You need both to be correct.
