I agree with Grin, Antec makes some great power supplies. I have two of them.
I would find the Antec you want and shop around.
Try Pricewatch.com but be careful of what you are getting.
Companies I trust are Newegg.com, ZipZoomFly.com, and Chiefvalue.com.
I would go to pricewatch and enter the Antec information. See if you can get a better deal, sometimes Newegg gives free shipping with mention of Pricewatch (Rare).
ZipZoomFly has free 2 day Fedex supersaver.
Remember to compare prices with shipping, sometimes Newegg beats everyone with shipping.
