I don't know if I would have suggested a lower-end PSU that is both only 80 Plus (compared to Corsair's 80+ Silver) and a drop of 50 watt drop off. Plus a $50 modular power supply? NO, I do NOT trust that.
The up from 7850 to 7870 also I'm not so sure was entirely necessary, cutting quality on PSU only to put in a GPU that requires more wattage? Yeah, not a good idea.
To expand on the power supply, for only $50, they seriously had to have cut corners on quality of the components, I really would stick with the nice Corsair one you were originally looking at, as it is I do not trust OCZ really anyways, but we still can come back to only $50 for a PSU that is both at least semi-modular and 80+? That smells extremely fishy and generic, nothing I'd want to power my rig with.

Also Drunkenvalley just found this and sent me to it, this is all levels of bad quality:

Basically some big issues I see there:
504 watts on the +12v, except, there's two +12v rails, so that means even more bad. 25A on each, a QUALITY power supply will have a single +12v rail, not two.
