This video shows how a power supply is supposed to respond when you push it past the power limits. The Gigabyte PSU explodes, but this EVGA 750 GT SuperNova probably won't.

This video answers a commonly requested topic from our GBT speedrun: "Can you show a power supply that works properly?" Well, here it is. This is how a power supply's OPP is supposed to work. And again, as a reminder, we believe there is clearly more wrong with Gigabyte's power supply than just OPP -- that just happens to be an easy way to demonstrate one of its many design flaws. We could run these all day on the 750 GT, but given that there's no clear end in sight when something works properly, we cut it off at about 30 minutes.
