Big enought power supply?

I am looking at an Antec NeoPower 550 for $40 and I was wondering if it is a good deal for my setup. I am running a Codegen 350XA right now and I think my computer is lacking power. The Codegen is 350W with one rail with +12V @ 12A. Should I get the new power supply and is it worth it? My specs are as follows:

ABIT IP35-E Mobo
Core 2 Duo E6570 @ 2.66GHz w/ stock HS&Fan
2GB Corsair XMS2 DDR2-800
EVGA GeForce 7900GS KO
WD Corsair 250GB 7200RPM SATA HDD
WD Passport 320GB External Storage HDD
Pioneer DVD-RW DVR-109 Burner
Codegen 350XA 350W Power Supply

Thanks for any advice in advance.

  1. The 550w should be fine, as long as you don't upgrade to a high end video card, such as the 9800gt or 250. I use an old antec 350w with my e4500, and it works great.
  2. Ok thanks. What about if I decide to get a 8800GT? Do you think it would handle that with 3 rails at 18A?
  3. Antec has come out with several series of power supplies and they have changed psu manufacturers. You might be better off with an Antec Earthwatts 500 watt power supply. It is more efficient than the Neopower version. With two +12 volt rails rated at 17 amps each it can handle just about any single high end video card.
