Seems a GTX 770 uses at most 200 W, so the two cards will be 400 W, leaving 250 W for the rest of the system. It should be fine. Looking at a review of the PSU, it's also fine being run at 100 %, so there's no problem.

It most definitely would be fine, I have an HX650 (your PSU is better) that used to run a X-fire 7950 and a 3770k that uses more power than that setup and it ran fine.

A couple of overvolted Classified or Lightning 770s?, then no, not enough. I mean overvolted by being able to go over 1.2125v.

Any other regular 770s in sli with a 4670k, the x650 will handle it no problem.

seasonic X has no problems delivering its rated power at a continuous basis as well as occasional peak demands that exceed its rated power. it's one of the best PSU's on the market that you can possibly buy.

not sure why people buy the best and still question its ability to do its job biggrin.gif it's the whole point of buying the best in the 1st place biggrin.gif
