Can my PSU handle CrossFire?

I have a Seasonic S12 600W that I bought some 5 years ago. It was a great PSU at the time but I'm not very good with PSUs so not sure if it's still good today for running a CrossFire setup.

This is my PSU (remember it's the 600W version): http://www.seasonicusa.com/s12.htm

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.

Help me, please!

It would be pushing it with two HD4890 since the relatively weak +12 volt rail on that old a PSU.

Ok, well, that sucks. I guess I'll have to skip it altogether or just pray it'll work. :p

It is one of those might work might not work! It is a quality PSU and has two +12volt rails of 18amps each but only 2 x 6pin PCIe connectors.

Ahh I see. Doesn't the 4890 require 2 x 6pin in each video card? In that case I'd be missing two connectors.

Most the cards ship with molex to PCIe adapter/s!
