Bottom Line

After a period of complaints and thanks in part to several reviews that clearly showed the problems with its\ P750GM and P850GM PSUs, Gigabyte was forced to acknowledge the problem and do something about it. So the company asked MEIC to make some changes in the PCB and adjust the over power and over current protection features, to offer adequate protection levels.

The revised sample we tested lacked the explosive attitude of the older model we tried a year ago. The major issue now is that you cannot tell the difference between the previous production batch and the new, with the updated protection features and the changes in the PCB. Gigabyte should use a version scheme to help buyers identify the new PSUs, but it didn't do that because it would kill all remaining stock.

Regardless of that issue, Gigabyte's P750GM cannot meet the performance of other similar spec products, including the Corsair RM750x, the EVGA SuperNOVA 750 G6, and the Cooler Master V750 Gold V2, the latter of which is the performance king in this category. Given that there is no easy way to distinguish the older units which had reliability issues from the new ones, we wouldn't suggest you purchase one unless you are 100% sure that it belongs to the latest production batch and you find it at a low price.
