I've tried 3 different power supply calculators and I've been recommended everything from 300 watts to 800 watts. Hopefully you guys can help. Below is a list of the hardware I plan to use

(No Overclocking)
EVGA 512-P3-N801-AR GeForce 8800 GT 512MB (only one - no sli)
Intel Core 2 Quad Q6600 Kentsfield 2.4GHz
OCZ Reaper HPC Edition 4GB (2 x 2GB)
Seagate Barracuda 7200.10 ST3250410AS 250GB 7200 RPM SATA (2x)
ASUS Silent Knight AL 92mm
ASUS P5Q Pro
DVD-RW Drive (1x)

I was thinking 800? just to be on the safe side. The last thing I want is get a PS that doesn't have a juice and have a part fry
 
A good quality 450W PSU is all that you need for that system. I recommend this PSU:
Corsair 450VX 450W PSU - $70

450? thats surprisingly lower than I thought. Is there anyway to test your voltages once you get it all hooked up to make sure everything is getting enough power?

The system you've spec'd doesn't come near 450watts at load.

Voltages won't tell you if you're getting enough power, it'll just let you know your PSU is operating within spec.
 
You could use a multimeter. However, that really isn't particularly necessary. Your system probably won't exceed about 250W of total power usage, which is well within the capabilities of the VX450.
 
450W is more than sufficient. Even a quality 300W would work just fine.

It's MORE than enough... I'm running a 485watter with quite a bit more load, though I'm probably cutting it a bit close.
