I wonder which of these PSU's I should get?

[TazExprez]

I am building a PC and wonder what PSU I should use. Here are the specs:
-X2 5050e
-Asus M3A78-EM
-2 sets of G.Skill 2x2GB (8GB total)
-WD 640GB Caviar Black HDD
-Samsung 22X SATA DVD Burner with LightScribe
*I might add another DVD burner in the future
*I might add the following video card in the future:
-ASUS EAH4350 SILENT/DI/512MD2 Radeon HD 4350 512MB

I looked through this forum and noticed that the power calculators are inaccurate. I am considering one of these PSUs:
-Antec EA380 380W
-Corsair CMPSU-400CX 400W
-CORSAIR CMPSU-450VX 450W
-SeaSonic S12 II SS-330GB 330W
-SeaSonic S12 II SS-380GB 380W
Are there any cheaper options, like $50.00 or less, or should I consider one of the above and which one? Also, is 80 Plus certification needed in order to save energy?

Thanks for all your help.

Sounds good to me. Free shipping, no rebates, quiet PSU. :thumbsup:

Thanks a lot for all of your help. I wonder if the Antec EA380 or any of the other PSUs have any issue with the case I just ordered. This is the case:
-SILVERSTONE Sugo SG01-BF

Thanks again.

The Corsair 400CX is $29.99 AR ($20) at Newegg today. Was $24.99 for a few minutes but Newegg jacked the price. A few buck or so cheaper after cashback through MS Livecash. Highly rated (both on Newegg ratings and with Anandtech's 300-430W supply roundup).

Given the price of the Corsair, it would be the best buy. Actually, it was $50 ($30 after rebate) just a few hours ago! And now it's $60.
