Power Requirment Question...

[hellshavocxxx]

Hello Everyone,
I'm currently building a new computer and I need some help determining what kind of power supply will be enough to run my setup. I have built computers before but this will be my first SLI rig. So this is what I have so far:
Motherboard: ASUS Crossfire IV
CPU: AMD Phenom II X6 1090T
RAM: OCZ Gold 16GB (4 x 4GB) 240-Pin DDR3 1600
Video Cards: 3x EVGA Hydro Copper 480 GTX
HDD: 2x Seagate Barracuda XT 2tb 7200 6gb\s SATA III
Crucial SSD C300 256GB SATA III
I also plan on overclocking the CPU to 4Gz+ and overclocking the RAM a bit too.
Also installed is a liquid cooled system powered by a Swiftech MCP655 12 VDC Pump witch uses between 24 and 30 watts.

Anyone know how much power I will need to run this set up at full capacity?
Thanks in advance for any help / advice!

Based on this:

750W is out, and I wouldn't bother trying to get by with 850W either. A 1,000W psu would probably not run at more than 750-800 max, and I'd be comfortable with that.

Better put in an air conditioner

Sounds like you're building a space heater!

I'll second the suggestion of AC... If the machine is in a small room, it will raise the temp of the room quickly when running full tilt.
