I'm sorry I never made a video :P but I make it a habit to test the psu on any pc I build. The TT PSU's are generally pretty decent actually but they do seem to be weak on the 3.3v stability, the voltage will stay in spec but fluctuate wildly across the entire range. I retired a TT toughpower 750 of my own for this reason, I watched the 3.3v on my multimeter while someone else played games or I ran 3d benches and after a while the 3.3v would start to go nuts and the pc would lock-up. As I said I test psu's on any machine I build so I've gotten to see characteristics of many and a fluctuating 3.3v seems to be common but doesn't neccesarily cause problems in all machines.

Your PSU has 4 rails, move things around a bit to lean on the rails equally and see if it helps. I would still test your psu's volts under load and idle conditions, it's quick, easy and may just save you some time.
