Thread Starter 
Will the corsair tx850m be enough to power 2x gtx 780

Thanks for your guys comment i was juat worried because i will be spending £1400 on upgrades and didnt want to have to get a new psu so 850w will be enough if its not then i will have to get a 100w or a 1200w soo after 1 guy said it will do for now what do you guys think?

Yes, it is suitable for SLI GTX 780s. Any quality PSU 760W or higher will be suitable.

It will get you by, but it will be running at 85 percent without any overclocks. Power supplies are most efficient at 50-60 percent loads, so if youre using up 600watts, I suggest a 1000-1200 w psu. It will run more efficient, doesn't cost a whole lot more and you can overclock without having to run at 90 percent capacity.

If you don't wanna spend any money, your 850 will carry you just fine.

There are so many holes in that logic i dont know where to begin so i will just say no to that post

850 watts is overkill even with two video cards hell a 650 watts could do it if there is no overclocks

A quality 850w unit is more than enough power gtx 780 SLI overclocked.

The difference between efficiency is rather insignificant, that the return cost of higher-efficiency from different loads will take years to get back if at all. Rather spending your money on a higher wattage unit, get a gold/platinum unit instead (due note that higher efficiency certification doesn't automatically equates to better quality), if efficiency is a concern. A 750w gold unit for example would be more efficient than a 1200w bronze unit.

Also, the only time it reach relatively close to 85% DC load (which will still going to be quite a bit lower) is when they are overclock and during Furmark+Prime95, while typical gaming load would be lower.

If you already bought it, the TX850m would be plenty.
