Power supply advice

I am in the process of replacing a Raidmax pile of junk PSU that burnt out on me after only a few hours of "service". Anyway I found three PSU's that I am considering buying for my case, could you suggest one over the other, or if there is a better choice for me to make, could you point me in the right direction. I would like to spend at the most $75.00 to $80.00.

The PSU's I'm looking @

ENERMAX Noisetaker EG495P-VE SFMA ATX 485W Power Supply

COOLER MASTER Real Power RS-450-ACLY ATX12V 450W Power Supply

ENERMAX Liberty ELT400AWT ATX12V 400W Power Supply

My system specs are:

Intel P4 3.2ghz CPU
1 GB Kingston PC3200 DDR ( 2 512 mb DDR's )
MSI 875p Neo-FISR main board
MSI GeForce 6600 agp video card ( 256 mb )
1 80 GB Western Digital HD ( 7200 rpm )
1 DVD R/W
1 CDR/W
2 120mm led fans
1 80 mm fan


Thanks for your help!
