Gigabyte UD750GM 750 W Review - No Lightning This Time

Photos & Cables »



After reviewing all other Gigabyte UD models, it's time for the UD750GM to get on the test bench. Bad memories from when I last reviewed a Gigabyte 750 W unit (P750GM) still haunt me, but a long time has passed since, and MEIC has improved the platform. For only ten dollars more, you can get a Corsair RM750x (2021 model) or Corsair RM750, so the UD750GM has to do a lot right to convince me it is a good choice for the money. Like the other UD PSUs, I plan to give it an extra-hard time to figure out whether it works correctly under all conditions, and I will compare its performance to the "legendary" P750GM.

Members of the UD line use improved P-GM platforms, with the 1000 W unit the first to boast ATX v3.0 compatibility primarily because of its 12+4 pin PCIe connector. However, in my new transient tests, it failed to meet all requirement of the specification. The UD750GM is not ATX v3.0 compatible, so it won't have to deal with those additional tests. At some point, however, Gigabyte will have to upgrade the 750 W and 850 W UD units to make them future-proof. We are in a transitory period right now. Most manufacturers are already working hard on upgraded PSUs with the 12VHPWR connector, which will be the standard for upcoming GPUs. Some board partners might insist on the 6+2 pin connectors for a bit longer, but everyone will eventually have to adopt 12VHPWR, so you better have a PSU that has one or you will have to rely on adapters, which is a bad idea for high-power applications.
