It should do but if I were you I wouldn't go for one. Go for a 600-650w psu - 80+bronze minimum, because PSUs work at their best at 50% load while good quality lens maintain efficiency to 80-90%. Basically, your psu will use more of the power it draws from the wall. If you had to go with a 550w, make sure it is 80+ gold certified

A 550 is plenty and has headroom, there's no need for more, unless thinking XFire in the future and then a 6-650 isn't enough, no need to get more than what you need.

I'm not wanting to start an argument, but considering how power-hungry the r9 280x is, I would personally prefer a 600-650w psu. However it is not my build, so the poster may decide to do whatever he wants

Everyone has his own preference, I've worked with a number of 280Xs and you could run it on a strong 500 actually, hence the 550 recommendation, of a good 550 preferably w/ 30 or more AMPs on the 12 volt rail, which the selection has. No doubt there are those that might even want more, I myself don't see a need for suggesting far more than what is required, having the headroom his selction has will more than suffice
