Speedrun Gigabyte Power Supply Explosion: Biggest Failure Yet (GP-P750GM)
50,301Gigabyte kept claiming that media testing was over "extended time periods," so we decided to speedrun the explosion of one of its GP-P750GM PSUs to prove a point.
Sponsor: Buy Corsair's 5000D Airflow Case on Amazon (https://geni.us/cnVP60)
For context, here's how the PSU is supposed to work: https://www.youtube.com/watch?v=2SleaZ68ZO0
THERE ARE ZERO CUTS IN THIS VIDEO BEFORE THE PSU FAILS. This is a single-take, one-shot speedrun to challenge Gigabyte's statements that third-party media testing was over "extended" periods of time, as Gigabyte tried to paint testing in the light of being ridiculous. The problem remains the same: Aris of Hardware Busters (Cybenetics) thinks that the MOSFETs are mistimed, and we agree. They're also not particularly good quality, and tend to go boom and hit runaway thermal scenarios (if not design faults first). OPP trips or not, we believe the Gigabyte GP-P750GM is poorly designed. The GP-P850GM has also had similar failures in our testing.
