Will 850w be enough or do I need bigger?

Looking at adding a full we loop to my sig and then maybe doing another 290... Looking at the outervision psu call it says I'll need a 1200w as it's going to draw 1048w from the wall with my desired overclocks...

Fair enough my CX750M is reaching its max (as with the 5820k overclocked it kept cutting off and restarting but this may of been a Windows issue as it didn't stop straight away after resetting overclocks but did eventually) but surely better efficiency and an 850w would be enough? Or does X99 consume loads of power compared to AM3+...

Spec me some good PSU's that will do, been looking at a 850 G2 but unsure if it will be enough

With 290x crossfire heavily overclocked and a 4790k also heavily overclocked i used to peak about 800 watts from the wall. So i had a bit to spare with the efficiency taking into consideration im only pulling 720 watts from the PSU at most. Your CPU might pull another 100 watts more than mine but the GPUs probably less as they were running at +150mv.

In short if ya go mad on the overclocks ya might be running on the limit.

Have you thought about just selling the GPU and grabbing a newer one instead of getting a bigger PSU, or are you using a freesync monitor so you feel your better off with the cheap upgrade to keep you going until Vega?

Thanks for the replies and the info, I am not running free sync currently and have looked at a new card but cannot justify the cost of what I would call an upgrade frankly
