so 1200W from the wall is not at all cutting it close on a 1200W PSU (just an example)
this is a very often overlooked fact when people are shopping for PSU's.
Im a bit of a newbie on how psu's work but generally have some sort of idea on how much capacity is required. My thoughts are that the system will draw above way above 1200w close to 1.5kw all overclocked running vantage or some benchmark.

That is what I thought. how long can a HCP 1200 handle that kind of load for?
I have watched the video, those are 580s not 480s, however it's crazy that it handles those wattage but I don't think it will last very long. I don't think it can't handle those wattage for a long period of time.
A good 1500w or 1350w should do the trick.
