My System Specs

Default MSI N560GTX-Ti Hawk
What size of PSU would be needed to do a SLI set-up using 2
MSI N560GTX-Ti Hawk video cards ?




Would a Corsair 80-plus Gold AX750 work ?

Or

Would the bigger brother the AX850 be better ?

750 is fine, probably the sweet spot.

Two of these (well not rly HAWKs but I think the twin frozr ii is what u ment) power draw as high as 710 from the wall when benching/folding for entire system. Now keep in mind PSU is not gold certified so its probably using somewhere around 670W.

So a single rail 750W psu will be enough to power such a setup...however I personally would chose to go with an 850W psu since i don't like stressing the PSU too much (they can get hot/loud/unreliable when functioning near their limits) so pay a little extra for the headroom!

i figure around 300 watts on the 12v for the pair,in normal gaming mode.
in more stressfull applications, you could add another 100 watts to be sure.

I have two Twin Frozr II 560Ti in sLI using a XFX 850 watts Black edition 71a 80+ silver...those PSUs are good, but also competitively priced....it's a Seasonic-built unit...

The wattage might be a little overkill, but I also have a lot of fans, and overclocking my CPU...I figure I have a little bit of extra...never hurts...
