Extra 300W enough for overlclocking?

PSU : Corsair AX860W

860W is overkill if you ask me. High quality 600W is even a lot of overhead room.

Current build is of 556W

are you really sure about that? that just seems a little...low... i thought 600w is just cutting it close for total power consumption

but, i could be wrong, what do i know?

Yo are not wrong.He suggested very a low wattage.

Nope. Computer's take up a lot less then people think. Skip to 2:10

600 will be just fine. Look at OC3D's 980 SLI video.

well ok, if you say so, I was just a bit dubious when krzyimprt said that 600w is even a lot of overhead room.

People over-estimate what PSU's they really need in terms of wattage. Jayztwocents did a video of this awhile back and I suggest you watch all of it. He has a highly overclocked build here.
