Help picking a power supply

[nxcess]

I need some assistance on picking out the right power supply to run this setup. So far, these are the components I will be using for this build.

1. DFI BloodIron P35-T2RL LGA 775 Intel P35 ATX Intel Motherboard
2. Intel Core 2 Duo E8400 Wolfdale 3.0GHz LGA 775 65W
3. G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800
4. EVGA 512-P3-N871-AR GeForce 9800 GTX(G92) 512MB
5. Western Digital Raptor X WD1500AHFD 150GB
6. Western Digital Caviar SE16 WD6400AAKS 640GB

As of right now, this is all I have picked out. I don't want to go any further until I've chosen a good power supply. Thanks

well I was lead to the corsair 620w modular... and with the limited space in my antec 900 case... I love it...

specs in sig...

A Corsair 520W modular is all you need. The 550W is cheaper, but not modular. Get Corsair PSUs from buy.com or zipzoomfly.com (or clubit.com).

I have another question. Would it be better to get a single rail psu with a lot of amperage on the 12V+ rail or a multiple rail psu with the amperage divided evenly across the 12V+ rail. Can you tell me about the Corsair 520W. I'm looking at the specs on the manufacturer site. If I'm interpreting what I'm reading correctly, It has 3 rails but the amperage varies on each rail depending on the load. Is this correct?

Read the PSU FAQ regarding multiple rails. Its only important when running an SLI/Crossfire system, IIRC. The Corsair 520W is actually a single rail, IIRC, so whatever needs power will get it. There's a good review on that PSU at jonnyguru.com. Check it out.
