750 W Gold ATX 3.0 power supply

The GIGABYTE GP-UD750GM delivers 750 W through an 80 PLUS Gold design that meets Intel ATX 3.0 timing and excursion requirements. A 120 mm hydraulic bearing fan with smart control keeps temperatures low while staying quiet. Fully modular cabling lets you connect only the CPU, PCIe, SATA and peripheral leads your build needs. Japanese main capacitors and six protection circuits back long-term stability.

Native 16-pin PCIe 5.0 cable for modern GPUs

A native 16-pin connector ships in the box and feeds up to 450 W to a PCIe 5.0 graphics card without adapters. The unit sustains 3x GPU power excursions and 2x total power excursions as defined by the ATX 3.0 guide. Builders moving from older fixed-cable or lower-rated units gain cleaner routing and headroom for transient spikes. Systems that do not use a 16-pin GPU will not use this specific cable.

750 W ceiling with Gold efficiency headroom

Continuous output tops out at 750 W, so configurations drawing more under sustained load will need a higher-capacity model. Gold efficiency reaches 70 % at low loads, reducing waste heat in idle or light-use scenarios. The compact 8.360 x 10.360 x 4.880 cm form factor fits most ATX cases, but builders with very small chassis should verify clearance against their case specifications.

Questions about this item

What case clearance do the 8.360 x 10.360 x 4.880 dimensions of the GP-UD750GM require?

The unit measures 8.360 by 10.360 by 4.880 centimetres, so verify your chassis lists at least that much depth, width and height for an ATX power supply before ordering.

How do I connect the native 16-pin cable for a PCIe 5.0 graphics card, and what mistake should I avoid?

Plug the supplied 16-pin cable directly into the PSU's 16-pin socket and the graphics card; do not use an adapter or daisy-chain a second PCIe cable, because the native cable is rated for 450 watts to the GPU.

When should I expect to clean or replace the 120 mm hydraulic bearing fan?

The 120 mm HYB fan runs under Smart Fan Control; clean dust from its intake every six to twelve months and replace the fan only if bearing noise appears after several years of continuous use.
