[yellosnowman]

which Coolermaster PSU is it?
I would recommend just getting a new PSU like Antec Earthwatts or corsair VX450
they are good quality and i think it might be enough for crossfire

P.S you should put the rest of your system specs up

If it's the Coolermaster Extreme Power Plus 390W you're talking about, it will be enough, if you don't overclock and limit the system to 1 HDD, 1 DVD-RW and a 65W CPU.

The recommended power usage for the 4770 is 450w. 390w might still be enough as 'gulli' said provided you have one hdd and a low wattage c.p.u., Its still pushing it..
