I'm building a computer and have everything but the psu.

I have

amd phenom II 965BE (125 watt version not 140 watt)
biostar a880g+
8 gb gskill ripjaws 1333 ram
Rosewill REDBONE U3 Black SECC Steel USB 3.0, eSATA, 3x 120mm Fans Mid Tower Computer Case
Seagate Barracuda Green ST1500DL003 1.5TB 5900 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive
onboard graphics




how big a power supply would I need? I was thinking 350 watts?

Without a discrete GPU a 300watt PSU will be fine! But if you are planning to add on later a suggest 400-500watts since the price difference between 300 and 500watt quality products is not much!
Cheapest I would go http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026

Any 300W will be fine ..................if your'e about to buy a graphic card later then just buy a 450W

Go with any Corsair , Antec , Seasonic ,XFX .............
