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

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.

I do not love the smell of burning mobos in the morning.

My $.02.

You want a 1300 watt PSU minimum.

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

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