I'm building a new PC, and its been awhile. I need to know if the power supply I have selected is sufficient for my build. I don't have the knowledge of psu's that I do in other areas. Any help is appreciated. Here is a link to it: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
This is the system:
Intel Core 2 Quad Q6600 (SLACR)
Corsair XMS DDR2 800 2gbx1gb
EVGA 8800 GTS 640mg
WD Raptor 150gb 10,000 rpm
Zalman CNPS9500 CPU Fan/Heatsink
Cooler Master Cosmos Case
*XION Supernova XON-600F14R-201 ATX12V 600W PSU*
The only other things I would swap out are the video card & cpu cooler.
8800GT is cheaper & faster. If you can wait a bit, the new 8800GTS 512MB should be out next week. It's delayed. Supposed to be out this week. It'll be somewhat faster than 8800GT. But the new reviews show the 8800GT takes the crown in terms of price/performance.
If you overclock, the Zalman will be loud at full blast. If you don't, it's whisper quiet. If you o/c, get a quieter cpu cooler like U120E, Geminii, Typhoon, Infinity, Ninja, Tuniq, etc.
I'd ditch OCZ that Maziar recommended and especially the Xion for something of better quality. SeaSonic, Corsair, Silverstone, PC Power and Cooling, and some Antec models would be the ones to look at. Something around 450-550W should be a good choice when it comes from a quality manufacturer.
What I'd suggest is the Antex TruePower Trio I got, it's 650W and certified at SLIZone.com to run two 8800GTS' at once. So you'll be well safe and sound, without too much overkill on the price and power.
