Ok so I just decided on a new a new build now all I need to know is the PSU to buy. Here are the computer specs:

Current Computer

CPU: Pentium 4 2.8GHz (Northwood)
Motherboard: (468) Asus P4R800-VM
Graphic Card: Ati Radeon 9600 256(agp)
Ram: 512(2x256) ddr Pc3200 400
HDD:120 gb

New Computer

CPU: Intel® Core™2 Quad Processor Q8400
Motherboard: Gigabyte EP43-UD3L (later on might buy one with SLI)
Graphic Card: GIGABYTE GEFORCE 9800GT 1024 PCX 2.0 HDMI
Ram: KINGSTON DDR2 4GB PC1066 CL5 HYPERX (2X2G)
HDD: Seagate Barracuda 7200.12 500GB 16MB

What I'm going to use the computer for

Im big on multitasking,(downloading something,converting audio and video,surfing the web,messenger,watching tons of movies(big movie fan),gaming and well the computer I have right now is nowhere near what I need and I mean not even close.

Other information

I also have a multicard reader, plan on buying another hard drive (another 500gb maybe more), planning on getting an HD moniter (I watch a lot of movies and series) and I'm going to get a Bluray burner.

The general rule of thumb is a high quality 500 to 550 watt power supply can easily handle a computer system with a single video. Corsair, PC Power & Cooling, and Seasonic all have reputations for high quality psu's that are stable and reliable.

Antec Earthwatts 500W or Truepower New 550W for a little more headroom. If you're sure about wanting SLI later, get an Earthwatts 650 or Truepower New 650 (or 750 of either) which will be able to run two cards later.

I don't really like the Corsair 450VX. It's just not that much better than the 400 watt.

400CX - 30 amp 12 volt rail
450VX - 33 amp 12 volt rail
550VX - 41 amp 12 volt rail.

If you want to stick with Corsair, and you decide the 400 is too small, you may as well jump to the 550.

just get corsair 650W or better, and keep it for like, 5-6 years.
