yes bro. Make sure your PSU is of good quality, not the generic ones. I don't know if the generic ones have a 6pin PCIe connector. You need a PCIe connector for that GPU.

The 7790 consumes around 160 to 170watts. The rest of your rig will consume about 200watts. That's a good headroom for your PSU (assuming it's a good quality).

Don't mean to be argumentative or cause a dust up but I think the 7790 is spec out at about 85W, yet ASUS says their card needs 150W? Not sure what gives here, I don't see any major power change on this ASUS card that would need that much more power. AMD and a write up here at Tom's says 85W on the 7790 with a 450W PS needed.

I have ran across this before at the ASUS site on card power draw, not sure why.
