jayesondhi :
Can you please help me find the cheapest 600w psu that is compatible with this? on ebay.
I don't recommend the case/psu you picked out. It is not a brand case/psu, as brand parts are highly recommended especially for a psu, for reliability and stability. Also, this psu is missing 6 pin pcie connector, which means you would be needing additional converter cable to make it work = wasted money. IMO, a high rated brand psu with 500W is better than generic 650W one. Is there a reason you want a 600W psu specifically? If budget is your concern, stick with 500W brand, high rated unit rather then a cheap generic 600W.
You can choose from corsair, ocz, cooler master, xfx, etc. check out newegg.com for reviews and ratings to pick out a few choices, and try to find the same one on ebay for similar prices.
