First time pc buyer. psu help!

Hello everyone.

I have an Antec 620w psu (http://www.newegg.com/Product/Product.aspx?Item=N82E16817371031) and was wondering if it will be enough or if I should upgrade to a 750 (or possibly 850??) Here's my specs

Mobo: ASUS M4A79T (http://www.newegg.com/Product/Product.aspx?Item=N82E16813131363)

Processor: AMD Phenom II X4 955 (http://www.newegg.com/Product/Product.aspx?Item=N82E16819103674)

Graphics Card: Radeon HD 5670 1GB (http://www.newegg.com/Product/Product.aspx?Item=N82E16814103104)

RAM: OCZ AMD Black Edition 4GB (2 of these) (http://www.newegg.com/Product/Product.aspx?Item=N82E16820227496)

I'm using one 1TB Internal SATA HDD, 1TB External HDD, Zalman 9700 Heatsink, Antec 1200 case.

lol, as you can tell I don't really know a lot when it comes to pc building. I am not building this myself, (I tried before and fried EVERYTHING) I'm just buying the parts seeing that it's cheaper this way.

Thank You to anyone who can help me!!!


also! my other question is if I want to upgrade my card to a 5850 (or higher) in the future, would the 620w still work?

Once again, Thanks!!!

I'd say 750 to just be on the safe side, especially if you upgrade to the 5850.

That Antec you have should be plenty powerful enough to power that system.

Look at the third system in my sig; it has a 9800GTX+ for a vid card and 4 gigs of ram (2X2G), plus it's running a MCP355 waterpump, all running on a Corsair VX550 psu. So you should be good to go with that Antec, which is rated for 70 watts more.
