I have two Powercolor Radeon 7770's that I am going to crossfire. My power supply is a Raidmax RX630Z 630 watt. Im running i7 3770S, 2TB Seagate 7200 RPM, 120GB SSD. I need to know if my power supply is big enough to handle the crossfire? This build is all about low power, low voltage, high efficiency, high performance. which is why the smaller power supply is in place.

630watts is enough except that Raidmax PSU is at the bottom of the barrel quality wise and can not be trusted to deliver its promised power. I suggest replacing it with a quality unit, example http://204.14.213.185/Product/Product.aspx?Item=N82E168...

I would probably say it would work. I've had plenty of cheap PSU's do the job. If it doesn't, buy a high efficiency PSU, like silver or gold, and make sure it packs the power, and is a reputable brand, because you can trust them so much more.

you would probably find something like a low 500 watt seasonic or other top quality psu will do that
