Need advice on PSU

post #1 of 4
Thread Starter 
Hi all,

I am currently using GTX560 Ti SLI and wanted to move on to GTX 780 and maybe having it SLI too in the future. My CPU is intel i7 3930K and have 4*8 Gb of memory and 4HDD and 2SSD. I have Corsair H100 cooling system in my rig with 4 fans and a normal LG disk drive. Currently I have a corsair AX850 in my rig and it is highly possible that I will overclock my graphic cards so I am wondering will 850W be enough for me to use?

Thanks,
Donald

Its more then enough power

Your power draw from the wall would be under 600 watts

You should be fine using an AX850 with a 3930K + 2x 780s.
