Default My power supply...

I have recently made the move to SLI with my GTS 320s since i got a low price for the second one, but i am slightly anxious over whether or not my power supply can handle two GTSs in SLI, since nvidia recomend 26A per GTS and mine provides only 22A per 12v rail, and i have 2 rails...which is shared by the fans, HDD and gfx cards....

I dont know if it will be a safe config to keep for long term use either...

do u think 44A total will be enough to power 2 GTS 320s, 2 SATA drives and the fans on my Antec 900? i dont plan on overclocking any time soon either.

I think i may have minimised the risk, though, since along with my card came a 6pin to molex adaptor for my card, where you connect 2 molexes up to the 6 pin adaptor for my GTS so half the GTS's power comes from one rail and half from the otehr rail for both my cards....will that help?

Hey DV, why not try the PSU calclator located here: Power Supply Calculator

May be worth getting two seperate calulations so: Power Supply Requirement Calculator :: Schrock Innovations :: free computer help power requirements calculator

700 watt can most def handle two 320's. My corsair 520hx or my antec 550true could handle two 320's.

PSU calculators are garbage

Most 700w PSU's should be able to handle it, unlessits a crap branded one like Apevia
