Power supply unit with 2 × 16-pin PCIe 5.0: Galax HOF GH1300 with up to 2,600 watts and two 12VHPWR

The Galax HOF GH1300 provides up to 2,600 watts of peak power (“peak”) and up to 1,200 watts alone via the two native 12VHPWR cables for the high-end graphics cards of the GeForce RTX series 4000 (“Nvidia Ada Lovelace”) available. The power supply is also 80Plus Platinum and fully ATX 3.0 certified.

2,600 watts for Ada Lovelace and overclocking

Galax, best known for its enthusiast graphics cards, has unveiled a new high-end category power supply through its official account on Chinese e-commerce platform Taobao. The Galax HOF GH1300 offers a rated power of 1,300 watts for OC systems with GeForce RTX 4090 (test).

Up to 2,600 watts for a maximum of 100 µs are guaranteed for the graphics card, because the ATX 3.0 standard stipulates that the power supply unit must deliver twice its actual rated power for 100 µs.

Galax advertises the HOF GH1300 in particular as an energy supplier for its own Galax GeForce RTX 4090 HOF enthusiast graphics card, which has two 16-pin connectors and a TDP of 666 watts, as well as the two even higher-bred overclocking derivatives OC Lab and OC Lab+. The graphics cards achieved up to 3.8 GHz GPU clock and 20 world records under liquid nitrogen (LN2).

But also the Founders Edition or custom designs GeForce RTX 4090 (test), the only have a 16-pin connector are suitable as energy consumers for the 140 × 150 × 86 mm (L × W × H) power supply unit.

Here, too, OC models with a very high TDP of up to 630 watts are offered. In practice, however, the extra power loss fizzles out and ruins the efficiency of the Ada graphics card.

The Galax HOF GH1300 is already offered in China exclusively via Taobao and costs the equivalent of 275 US dollars, as the Chinese website ITHome first reported.
