Introduction

Gigabyte had huge problems with its PG-M line, and everything started with our review of the P750GM model. They released revised models after the plethora of complaints from users and reviewers worldwide, but there was no way to tell the difference between the old and new models. To avoid further bad press, Gigabyte re-introduced the newer units as part of the UD line. These use the revised P-GM platform with lower OCP and OPP triggering points, and some minor PCB changes. After the release of the ATX v3.0 specification, which included specifications for PCIe 5.0 PSU compatibility, Gigabyte was the first to release a PSU featuring a 12+4 pin connector, while also claiming ATX v3.0 compatibility because the connector alone doesn’t make a PSU ATX v3.0 compatible. As such, Gigabyte upgraded the UD1000GM model to the UD1000GM PG5.

The UD1000GM PG5 uses a fully modular cable design and has compact dimensions for the capacity. Because of the small case, it has to use a 120 mm fan combined with an aggressive fan-speed profile. As such, the PSU is rated Cybenetics Standard+ (35–40 dBA) for noise output—don’t expect it to be quiet. Moreover, the unit is rated 80 PLUS Gold and Cybenetics Platinum for efficiency. At the time of review, the price was $160, which is below competing offerings that lack the new PCIe connector.
