Power usage

Hi
My new computer will be:

Motherboard: ASUS P5K-E/WIFI-AP
CPU: Intel Q6600 CORE 2 QUAD 2.4GHz BOX
CPU Cooler: Thermalright Ultra-120 EXTREME
Graphicscard: ASUS EN8800GTX HTDP 768M
Memory: OCZ DDR2 PC2-6400 PLATINUM 2GB KIT

Power: Cooltek 600W Real Plug Power

What you do think, how much is this power usage? My current PC eats 170W in stress

Should do. As long as that's a stable psu.

Edit: Just looked it up, it should be able to handle it, dunno for how long, that just depends on the company.

It looks like a stable PSU, judging by the review I just looked at.
