Gigabyte UD1000GM PG5 1000 W Review - The First PCIe 5.0 PSU

Teardown & Components »


The box is small because of the PSU's compact dimensions. At the face, mention is made of the PCIe Gen 5 compatibility, but Gigabyte forgot to replace the ATX v2.31 mention on the back with ATX v3.0. The unit is listed as ATX v3.0 compatible on the product web page.

Foam spacers surround the PSU, providing good protection.

The bundle only includes the necessary bits and bobs: a user manual, fixing bolts, the modular cables, and the AC power cord.

At the face of the PSU is the power switch and AC receptacle. There is no switch to toggle the semi-passive operation on/off.

The power specifications label is on the bottom of the PSU, which it covers nearly entirely.

Including the 12VHPWR socket, the modular board has nine sockets.

At only 140 mm long, this PSU is compact.

Both EPS connectors are on the same cable, so utilizing them fully won't be possible. Each EPS connector should be on its own dedicated cable. Moreover, it would be nice to see three PCIe cables instead of two.

There is no need for an FDD adapter, and the 4-pin Molex connectors should at least be 150 mm apart.

The AC power cord.
