Problem with OCZ GameXtreme 600W

[Rucanor [X]]

Ok...Swapped out a Cooler Master 430W with an OCZ GameXtreme 600W...Everything powers on (MB lights up, hard drives kick on...the whole shebang) but nothing happens....Removed all my Ram, disconnected the 250mm door case fan (although i think deductive reasoning says it cant be a power issue if i had less wattage before and it all ran) powered up....nothing...no screen, no beeps...

Its a power supply...How could it not work?

System is MSI K9A2 Platinum board, AMD 4800+, Thermaltake Armor 8003, 1 Raptor drive, 1 160 Gb Seagate drive, 1 500 Gb Maxtor drive - all sata

Help?

Try turning on the mobo by using the screwdriver trick (short the two pins on the mobo for the power switch by touching the tip of a screwdriver to them). Also MSI mobos have been known to not like certain types of PSUs (Neo2-FR has issues with cooler master real power series). Try booting up with just bare minimum, ram, proc and video card to see if you can get it to post. Also try a cmos reset.
