Dead PSU, New choice sufficient??

[lagerter]

My son needs a new PSU. He has a DFI 865PE-TAG, 250g HD, 120g HD, DVDRW, CDRW, 2x512DDR (not sure what else you need to know)... not a heavy gamer, mostly will be doing video and web design.
I've tried reading up on it but haven't gotten very far with understanding rails, volts etc...
Here's what we are considering:

Antec TRUEPOWERII TPII-550 ATX12V 550W

Antec NEOPOWER 480 ATX 480W
http://www.newegg.com/Product/Product.asp?Item=N82E16817103924

FSP Group (Fortron Source) AX500-A 500W
http://www.newegg.com/Product/Product.asp?Item=N82E16817104934

Any other comments, suggestions, criticisms (easy on the latter ) would be greatly appreciated! If anyone has one for sale, we would be interested, also.

Thanks!!!

Any of those will do, but you may find at least the Fortron cheaper at eWiz or Actbuy

Thanks O. Wolf! Never dealt with either of those 2 companies but I'll check them out.

Neither have I actually - I'm from Canada

Heard fairly good things about them though.
