PSU for multi-gpu

If I wanted to have two 980ti, what size PSU will I need?

I've been looking at 850 psu, would the be enough?

Thanks,
Cris

Thanks guys, I Already have an old antec Quattro 850 semi mod from my previous build 6 years ago.

You think I would be ok with it, or is it advisable to go for a clean start?

Pairing them with which CPU?

Will you be OC'ing the CPU?

Will be OC'ing the GPU's using a custom bios?

It will be a mAtx build on a corsair 240, with either the 5820k or 5930k.
My understanding is that 5930k will be better for multi gpu.

I don't think I will be OCing anything

Free performance and all

lol forgot for a second I am in the "overclockers" forum. Very rude indeed

The thruth I no very little about it, what PSU should I get if I was going to OC?

Play it safe. Clean start and better PSU. 6 years is a long time. Especially if it's out of warranty, and the PSU company will then not cover any damages to the rest of the hardware if the worst were to happen.

Another vote for the G2.

Thanks for your feedback, I think you are right. Will keep my old PSU as a backup, and will get the G2 as you suggest.

What the biggest one you could get? Is there a drawback for getting an over the top PSU?
