i know people are going to quote the amd website but i know they are just covering their asses for all the terrible psus out there.

i have a SG05B silver stone case with a 300w fsp 80+ psu. i have a gtx 560 ti but i think i could swap it for an hd 7770

More about : 7770 300w psu

If you try it and it works you would be ok for a while .
In a few weeks the psu will probably start to fail. You didnt say what the cpu was. If it is only a twin core you might get away with it longer.
when you have money Go for a cx430, they are good and cheap.

Depending on what CPU you have, the GTX560Ti might even run fine in it. Generally though the 7770 should run fine.

Depending on what CPU you have and how much extra stuff you might have in there, it could be a tight squeeze. Not all FSP PSUs are created equal either... their Aurum series (80+ Gold) may be pretty good but their lower-end series (usually those only rated 80+/80+ Bronze) are often not so good so you might have long-term stability issues running it at ~200W.

Silverstone ST45SF $64.99
That would basically run most of todays GPU's.

Slightly cheaper on amazon and you can get free shipping.
