Newbie Power Supply Question

[mtschirret]

All:

I want to purchase a 7950GT PCI Express card, which carries a requirement of a 350W PCI Express compliant system power supply (with 12V current rating of 22A or more)

The PSU I'm looking at is this one:

My question is: The output is rated at +3.3V@23A, +5V@17A, +12V1@17A, +12V2@17A, +12V3@17A, -12V@0.8A, +5VSB@2.5A

Because the +12V1, +12V2, and +12V3 are all under 22A, does that mean it won't work? I'm only looking for a 450W PSU or higher, and can't seem to find any less than $200. I'm not a power user, but have a Core 2Duo E6400, (2) 250GB SATA drives running in RAID 0, 1GB RAM, (2) DVD EIDE drives, and the GPU.

Thank You!

The antec would probably work fine. 22A seems like a pretty lofty number to my a baseline requirement. I'm running a 7900GTO on my Antec Trupower II 430 which is rated at 17a on the +12V rail, it's been running fine (and well overclocked) for a while now, it also lists a 22a suggest rating. However, most people say that amperage on the +12v rail is the most important thing. That in mind, given the stated amperage requirement, maybe on of these Enermax PSUs would work for you (Enermax is pretty well regarded in the PSU market)
