Does the Corsair RM1000W PSU provide enough power to two xeon 2630v2 and a 280X?

I'm planning out a new build and I haven't done a dual cpu system before. My two concerns are whether this PSU will power everything and if it leaves room for upgrades/additions? if it doesn't, are there any other solutions within this price range that are reccomended?

my full parts list is here http://pcpartpicker.com/p/xpGmWZ

Thanks in advance!

It is an overkill. 2 such CPUs under max load draw between 80-100 watts (maybe). 280X uses approximately 250W under full load. Add 50W for your other components (mobo, addon cards, hard drives) and you get to 500W as the worst possible theoretical scenario, which will never happen in practice. Most likely it will be closer to 400W while playing both CPU and GPU intensive games (in games most of your cores will be unused anyway, and if you do a lot of CPU rendering, your GPU will be mostly unused - hard to stress both CPUs and GPU to the max at the same time).

Get RM650W model - not only it is far better suited for your needs, it is also a better model in terms of quality (better capacitors and made by Channel Well Technology).
