I'm starting a new build and want to know if the power supply will be adequate. I am using an ASUS 990FX board, 16GB of PC1866 ram, and a FX8350. I want to be able to crossfire 7970's or similar. It will have a bluray drive and a DVD writer and probably 3 7200 hard drives. I have the following power supply. Will this be adequate? I also have a BFG 1200 watt power supply that is in another computer. It is 4 years old but has not seen heavy use.
