The Gigabyte is a decent and reliable PSU. Given the bad history of the P750GM, we pushed it a lot, more than usual, to check if there were any problems, but the PSU did OK, surviving all of our tests. The MEIC platform that it uses offers high efficiency, and it has great soldering quality. Still, we would like better filtering caps on the secondary side and a higher quality fan, which doesn't use a hydrodynamic bearing, as Gigabyte states, but a rifle bearing. The compact dimensions and the correctly set protection features are two more assets of this product.
The competition is tough in the mid to high-capacity PSU categories, so Gigabyte has to do better to stand out from the crowd. The UD750GM is not a bad product, far from it, but the competition is intense, and it doesn't offer something notable besides a reasonable price (which at the time of the review was $80). If you can get a
Corsair RM750x or an
EVGA 750 G6 for $10 to $20 more, it's worth spending the extra money. If the price difference is higher, you should consider the UD750GM.
