What psu size will I need for a 7850??

A quality 550watt would be plenty for that!

okay, will a 500 or do i need the room if i want to oc

You would probably be fine with a quality 500watts but since they are in the same price range I would go for a 550 for extra headroom. Just pay attention to how many amps they have available on the +12volt rail!

okay what about this cheap 600 watt- http://www.newegg.com/Product/Product.aspx?Item=N82E16817139028

That is a pretty nice looking PSU. It's got a single 12v rail, which is hard to find at that price range, which puts out 40A (480Watts).

I would expect it to be a pretty high quality unit, I've heard corsair PSUs recommended a lot as well.

The 12V output should be sufficient to overclock both your card and CPU.

Yes a great budget PSU!
