Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

We got our hands on an updated P750GM unit, which didn't explode during our extensive tests. While that's definitely a step up over the previous model, it's not enough, since its performance is not up to the competition's levels. This is not a unit for our best PSUs page. You'd be better off taking a look at the Corsair RM750x and the XPG Core Reactor Reactor with similar capacity. 

You could find many references online to problems about the Gigabyte P750/850 GM units. TechPowerUp's unit blew, and the same was the case for several units tested by the Gamers Nexus YouTube channel. All this fuss eventually forced Gigabyte to issue a statement and take back some of these units. According to Gigabyte, the problem was due to the over power protection high setting, which was lowered in the new models. Unfortunately, there is no way to distinguish the new production P750/850GM units from the original ones. But we are certainly curious to find out the differences between the old and new platforms.

    I don't know man. Once beaten, twice shy. Even with the fixes, this is not a PSU that I will use or recommend. To me, the worst part is how Gigabyte tried to shrug off responsibility for the explosive PSU that are potential fire hazard, and put off fixing the shortcomings of the PSU for almost a year.

    The explosive p-gm is discontinued. It has been replaced by the UD series which are "fixed" allegedly.
