Is a 400w PSU enough for...

AMD Athlon II x3 445 Rana @ 3.1GHZ
ATI Radeon HD 5670 1gb

Here's the PSU:
Newegg.com - Antec NEO ECO 400C 400W Continuous Power ATX12V 2.3 / EPS12V 80 PLUS Certified Active PFC Power Supply

Would you reccomend a different one? Try to be around 40-60$ on it though...
Thanks.

Should technically be fine.
This is better for only $10 more, though.

Alright, thanks... I added that OCZ to my cart :) Just want to make sure everything is good for ~$500 before my mom orders it for me for Christmas.
