Another will this psu be enough...

[mattsnow]

My new system is:

Intel Q6600 G0 (maybe some overclocking)
Gigabyte EP45-UD3R
8GB 1066 Kingston DDR-2
BFG 8800 GTX

2 hard drives, a samsung dvd / rw, and some case fans.

The PSU: Corsair 450 vx

This has one 12v rail that supplies 33A, I think this should just be enough for the system but I'm not sure.

hmmmm... just to play it safe: 550w? Here's a variant at that level from Corsair: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139004

Well Yes...that 450W is suffice for your setup...But like r_manic said, get the 550W to be safe...

Actually, you have some, but not a lot of, reserve power.

Q6600 OC'd 10 amps @12 volts (my Q6600 OC'd to 3.6 GHz - 9.5 amps, measured
8800GTX: 11 amps at 12 volts
MB: 5 amps @ 5 volts, negligible 12 volts (my GA-EP35 - 3.5 amps ,measured)
RAM: 12 amps @ 3.3 volts max (my RAM 2GB, 3 amps, measured)
Drives: less than 4 amps @ 12 volts, 3 amps @ 5 volts
Fans: 1 amp @12 volts

I estimate that a 450 watt Corsair would run at around 85% load. 450 watt PSU will do. 550 watt better. I would use a 650 watt PSU for a similar system. Oh, wait. I am.

I try to operate my computer power supplies at 50 - 65% load (military electronics background.

thanks guys, in an ideal world I would play it safe and have more room for expansion but I only get £20 a week from paper round + jobs and I already have this 450 vx so I'm going to use that.

on a side note I think I'm going to go for an 8800 gts and not gtx, does this have any more / less power consumption?

The 8800GTS consumes less than the 8800GTX. You should be OK, but don't overclock the CPU because that puts more pressure on the power supply.

You'd be better off getting a 550W Corsair like many members said, its better safe than sorry lol.
