I'm using a Sapphire Radeon HD 4890 and I'm looking at adding another one for CrossFire to squeeze out what I can from this system for another year. I'm also using a Phenom II X3 720 2.8Ghz overclocked to 3.4Ghz on stock cooling. Two hard drives and three case fans are installed.
Can my PSU handle these in CrossFire? I'm not very good with PSUs so if anyone could tell me before I go ahead and buy the second 4890 I'd really appreciate it. Not even sure if it has the power connectors available or not.
