Power supply required for Sli GTX 670 FTW

post #1 of 3
Thread Starter 
Right now I have Power and Cooling Silencer MK III 600W Modular in my build.
Was curious as to what would be the lowest safe watt Power supply would be required to handle two GTX 670 ftw's?

If you're using them in an IB/SB system then it should be ok (but you are on the edge here). You might wanna go up to 700w or if you own a SB-E system.

46A on +12v rail which means 552 watts. I would say its just enough for GTX 670 SLI. I wouldn't advise heavy overclocking. If you stick to stock speeds you should do fine.

But it might be better to spend on a new PSU.After spending 800 bucks on GTX 670s its better if you get a 750W PSU. here is Corsair CX750 psu for 81 bucks after promo code PSU106 (offer ends 10/6 ). 62A on +12v rail. thats very good.
