It's possible but very much in the danger zone.

Totally fine. The XFX PSU has 44 amps on the 12v rail, and the 280X only uses up to 42 amps under extreme load.

Or over clock, add fans, add drives, add USB devices, add anything... That's very border line.

That's a power hog of a card that uses up to 300w itself

It definitely does not. Stop spreading misinformation about PSUs. The 280X recommends 42a on the 12v rail, where as the XFX PSU has 44a, and the ampage on the other parts is fine for the CPU and motherboard.

Learn to do better research. It does.

that PSU is EASILY capable of supplying 300w to the GPU. Take a look at this review on JonnyGuru: http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=225 His REAL WORLD tests show that the power supply can supply a maximum of 528w on the 12v rail ALONE, and I'm not a mathematician, but 528 is a considerably more than 300, and leaves ample room for HDDs, and molex devices, which are the only other parts of the computer that use the 12v rail.

Sure it can do that, if it wasn't also supplying over 100w to an over clocked cpu plus all the other components. As I said originally, it's very border line. I didn't say it won't work, but it's a hell of a risk. Why tempt fate when you can spend a small amount more and be sure there's no problems?
