IMHO, 1100 watts is pushing it and too low, leaving you no room at all when considering the overall average 80% load.

Agreed. That PSU has 1080W on the 12v rail, it leaves you with very little wiggle room, but it is doable (not recommended).

You want a 1300 watt PSU minimum.

FWIW, I have 3 r9 290's on an EVGA 1000w PSU, and my killowatt meter says 999-1030W at the wall. Given at 100% usage, the psu is 87% efficient, that means the 3 cards + mobo+proc +1stick of ram = 870W or so. If the 290x is similar, you will be fine.

if you go with a sempron, and undervolt GPUs, and use SSD, and power supply is gold+ rated, it could be OK, but it depends
