PSU Crysis help!!!!

[oz73942]

I just bought the http://www.newegg.com/Product/Product.aspx?Item=N82E16817139005, But now that i recieved it think i should have gone with the 750 watt model. I plan on running 5870's crossfired, an i-7 920, two harddrives and two cd roms. Did i make the wrong choice with the 650?!?! Thank for all the help!!!!

A 600 watt psu with 4x 6 pin connectors is reccomended for the 5870 in crossfire, other than having to use power adapters, the TX650 should be fine.
