My 3 yr old PSU from Antec, I think called an a SmartPower, anyway its only 380 watts, and the 12v is only 16a, which I think is pretty small. Anyway most likely its too small, how much power do i need for this:

Intel c2duo 6750
MSI P35 Neo2-FR LGA 775 Intel P35 ATX Intel Motherboard
Crucial Ballistix Tracer 1GB ddr2
8800gt of some sort
2 hds, 1 burner, a few fans

My guess is about 450, but Im aiming for 500, but what Im also aiming for around $60 or less only if quality is still good.

Whats better?

I wouldnt give the APTIEVA the time of day, but the thermaltake and seasonic would be a good budget PSU for that rig.

you have enough power with your old one

I would go with the Seasonic since it's 80% efficient. Also, get more RAM. Having only 1GB will bottleneck your system.

Thanks a lot guys. I'm new to the forum and my 1st post "would have been" a request asking why won't my old (5yrs) Antec 300W PS work with my AM2 CPU and ECS MB. I figured that the PS wasn't hefty enough and the PS calculator verified it. The PS listed above sound great too. I think I'll be ordering 2 of the Seasonic 500W Ps later today.

Wouldn't it be great if the MB manufacturers would publish the pwr requirements of their products?

With the system in my sig 350 watts, but don't forget about Amps. Theres no PSU out there that has 350W with at least 30 amps on the 12 volt rails and thats just for my 8800GTX.

If you're suggesting the motherboard manufacturer's publish the power requirements for their different boards, that's virtually impossible. The motherboard draws relatively little power on it's own. The video card and processor in the system are usually the two highest drawing components in a high-end system, and the "top of the line" changes on a fairly frequent basis. As an FYI, the video card and processor manufacturer's usually publish some sort of information on how much power their products draw, but you'd have to do some research to find it.

I'd go with that Seasonic if I were you - I'd also pop in a 2nd GB of RAM as suggested above.

You really don't need a 550W Corsair, the 450W will be more than enough.

He really doesn't need a 550W PSU now, but what about in the future? If he were to get a 550W PSU now he may not need to upgrade again in a few years like he is having to do now.
