Hi, I have a 850W SeasSonic PSU. Will it be enough to power 2x ATI R290x or 2x GTX 780? My desktop has a I7 4770k, a SSD and two HDD. Thanks.

Okay, but you will not be able to overclock the two graphics cards and the CPU all at once.

I know this post is old. but to make clear with the r9 290x you need at lest 1000W and with the 790 gtx you will need 800W but to overclock and have little more space I would do 1300W for the 290x and at lest 1000W for the 780 gtx
