Difference between these PSUs/suggestions?

I'm going to be running a system with the following:

Intel Core 2 Quad Q6600 Kentsfield
Radeon 4850
2 sticks ram, 1 HD, 1 CD/DVD rom
This motherboard (I think it's compatible )

I've always used Antec for power supplies and had no problems at all, so I was looking at Antec Basiq 500W and Antec Earthwatts 430W. Will these do the job, and if so, which would you suggest? Or what power supplies of some other brand would you suggest (I'm not completely set on Antec, but I do like them)?

Noise doesn't matter to me as I'm in the same room as 2 other loud computers anyhow. My main concerns are:
1) Will it make my computer run?
2) Is it inexpensive (50 dollars or less; this is a budget computer/dissecting my old computer for parts deal)

I've tried reading up on all the fancy details of PSUs with amps and rails and whatnot, but apparently I'm too retarded and don't understand it all (and/or too lazy to take the time to learn it all ), so any help would be appreciated.

Also, what are some other good brands to look into?

Thanks!

500w @ 30amps minimum for 4850, especially with a quad.
EA500 @ 34amps

The Basic500 has 35amps but it is not of the same quality, or 80%+

From what I've heard , they are shipping the Delta unit's now. That being the case, a person could save $25 by going here

Antec switch oems on the EA 430 and 500, from Seasonic to Delta.
I haven't personally purchased from them but have a friend who did, he say's the transaction went smoothly.

There's something very wrong here, first I can't edit post then "my" gets changed to "me" and can't be editted either
