# 4GB DDR2-800MHz dual channel SDRAM (4x1024)
# 1GB NVIDIA GeForce 9800GT, 2 DVI, HDMI adapter
# 750GB 7200 rpm SATA 3Gb/s hard drive
# LAN port on system board (10/100/1000Base-T), no wireless LAN
# LightScribe 16X max. DVD+/-R/RW SuperMulti drive

edit:
Get a quality PSU from Corsair, PC Power & Cooling, Antec or OCZ. A quality 450W+ (ie 450VX) is enough to power a single 9800GT.

tomahawk you should have at least 650 watt for your rig to be on safe side. Inadequate PSU in the most overlooked potential problem maker in new system builds. I have used both a 750 PSU ($130) and a 860 PSU ($240) both from PC Power & Cooling. I run the about the same options as you do except in the 750PSU rig, I have a 4870VGA and in the 860 Watt a 4870x2. No power problems whatsoever. Eliminate a number of potential problems and dig deeper to have adequate power.

@OP: The #of watts is irrelevant. What matters is the +12 amps and the build quality. Like I said before you can run a 9800GT on a Corsair 450VX. Please post EXACT PSU model.

It has the enough amps but what is the brand? I recommend yo get a quality PSU from the manufactures I recommended above. My personal favourite is Corsair or PP&C.
