Upgrading Psu

[Beachum]

I have recently purchased an r9 280x and I'm looking to buy a 750w power supply to go along with it, however I am not completely sure what to look for in a good Psu besides the 80+ bronze/gold ratings or what not. I have an Haf 912 case, and my budget is up to $150 since i believe that is more than enough.

Are you planning on crossfire'ing 280X's? If not, a 550W would be more than enough for a 280X. If you are or want the option, go for a 750+.

CX500M / CX600M for $49.99 after rebates, both are 80+ bronze.

EVGA SuperNOVA 750W for $59.99 after rebates, also a 80+ bronze.

For something on the 80+ silver/gold/plat range.

Corsair HX750M for $89.99 after rebates, 80+ gold

Seasonic G 550W for $85.99, 80+ gold

Silverstone Strider 600W for $85.98 after rebates, 80+ silver

EVGA SuperNOVA 750W for $99.99, 80+ gold

i dont plan on crossfire, however i dont see the point of spending money for an extra 50w may as well get the 750w for any future upgrades. The 80+ gold Corsair looks pretty nice and will probably be the one i choose thanks.

The Corsair HX is $40 off it's normal price, so thats a pretty damn good deal at the moment and comes with a 7-year warranty to boot.

Just as a small additional point, adding a decent bit "more" PSU than you think you'll need often works out well in a couple of ways. Firstly for efficiency the ratings are usually based on a highly loaded but not fully stressed PSU so as you get closer to the full rating, efficiency can drop off a bit. Secondly, noise. There's usually a fairly considerably "ramp" in fan noise once you cross the 50/60% load mark on even fairly quiet PSU's.

If you have the cash spare, get something a bit bigger (as you seem to be intending).
