could be the PSU.... maybe. 600w and a 36A 12V rail might not be enought for it, especially if it isn't well constructed. I would think it would at least boot though, maybe I am wrong. If you had another PSU to test with it would be helpful, but I know that probably isn't in the cards.
Is the PSU new? what brand is it? any links to the item?

The PSU's label certainly looks sufficient, but what brand/model is it? The label could always be a lie, and knowing the brand and model will help.[/quote
