PS for Dimension 4600

I have a Dell Dimension 4600 that is about 3 years old.
It needs a PS and I was wondering what I can use in the place of a Dell part.
I have been told there are some others out there cheaper that will work on it.
Not sure of the specs you need so here is some

HARD DRIVE, 40GB, I, 7.2K, 80G/P, SEAGATE-ALPINE
CARD (CIRCUIT), GRAPHICS, 64MB, NV18, DIMENSION
DUAL IN-LINE MEMORY MODULE, 256, 333M, 32X64, 8K, 184
PROCESSOR, 80532, 2.4G, 512K, 533, SOCKET N, DECISION ONE


Thanks for any info.

 

Bump. Any ideas out there?

Thank you ASUS. The Dell brand is over my head and I cant figure out which one of the replacements go to a Dell. I feel like a complete idiot lol.
