Would love to buy one or more of these, but question regarding the PSU...
Is it a single 900w PSU that comes w/ the unit? if so, whats its 80+ rating?...is it a quality PSU?

I would assume, to make it USA 110v usable, all I gotta do is plug it up w/ a standard PC power cord right? (Im assuming the plug on the PSU for power is the same as any other, its the side of the cable that goes into the wall is the only thing thats different....)
