Would 550W be enough power for this build though? I know the 390 is power hungry.
Oh it's plenty!
The only problem with this page is, they didn't show the details like they did on this page:
As you can see, the R9 290X only pulled 4W more by itself, so let's use those details instead and pretend that they are for the R9 390. Here we go:
With one R9 390 under full load in their system, their PSU pulled 396W from the wall outlet. If I assume that their PSU was 90% efficient while pulling 396W from the wall, then that would mean that their computer pulled 356W out of the PSU. If I add about 150W for overclocking the 6600K, then that makes the computer pulling 506W out of the PSU. Your power consumption while gaming though would be lower, riding about 450-475W which would be easy for Cooler Master V550.
There would be nothing wrong with getting a 650-850W PSU though, except you'd be spending more money. Well, there's the 750W EVGA B2, which is a surprisingly good unit:
It's $59.99 after NCIX's $30 mail-in rebate!
Now that I have posted my reply, I will read the ~30 replies or so just to see if there's anything that I missed.
