You should specify what graphics cards you are planning on running, as 1GB of memory can be found on the low end cards as well as the high end ones. But right off the bat, I'd say at least a good 750W if you are running CF with some higher end cards, and also want a bit of headroom for overclocking. Something like a Corsair HX750/AX750, Antec TPN 750 etc.

Med range graphics card.

Gigabyte GV-R575OC-1GI Radeon HD 5750 1GB

So at least 750w?

With a HD 5750, you'll be fine with a 620W PSU.

 

[JoeBob]

Yeah, the TDP of a HD5750 is only 86W, so you don't need anything really beefy for even two of them.

A decent 500W PSU would be plenty for that machine. This Antec PSU comes in at $35 after a mail-in rebate and would be perfect for the job, so long as you aren't picky about having something that's modular or that has higher efficiency: http://www.newegg.com/Product/Product.aspx?Item=N82E16817371030&Tpk=neo eco 520w

I've always found the eXtreme power supply calculator pretty useful to determine watts, but quality is important just as much

The manual for the graphics card says I need a minimum of 600w if running two in crossfire. Is this just Gigabyte covering themselves?

for $50 plus shipping i would consider that bfg ex1000 refurb.way overkill for your specs but what a great price and plenty of juice for most any future upgrade.

I would not really go on their info, people's advice here and online power supply calculators can give you much more accurante info

it is them just covering themselves and taking in account overated/sub par PSU's i think

Yeah, pretty much.
