GIGABYTE GP-UD750GM PG5 V2 750W Gold Modular PSU ATX 3.1
The GIGABYTE GP-UD750GM PG5 V2 750W Gold Modular PSU ATX 3.1 is a fully modular power supply built for enthusiast builders who want next-generation GPU support and clean cable management in a compact chassis. It delivers 750W through a single +12V rail with 80 Plus Gold efficiency, and its native 16-pin connector supports PCIe Gen 5.1 graphics cards drawing up to 450W — including the GeForce RTX 50 Series.
Why this product
ATX 3.1 with native 16-pin PCIe Gen 5.1 cable
The included 12+4 pin cable delivers up to 450W to the latest high-power GPUs, with support for 3× GPU and 2× system power excursions as required by the ATX 3.1 specification.
80 Plus Gold: 90% efficiency at typical load
Gold certification means less energy is lost as heat, keeping the system cooler and reducing fan noise under everyday workloads.
Compact 140mm depth fits tight cases
At just 140mm deep, it is compatible with space-constrained mid-tower and compact ATX chassis that cannot accommodate standard-length units.
Single +12V rail for stability and overclocking
All output power routes through one +12V rail, simplifying cable selection and delivering consistent power delivery suited to overclocked hardware.
Semi-passive fan stays silent under light loads
The fan remains off when the system is idle or below 20% load, and the hydraulic bearing design extends operational lifespan during sustained use.
Six protection circuits for hardware safety
Over-voltage, over-power, short-circuit, under-voltage, over-current and over-temperature protections are all integrated to guard connected components.

- Compatible with Intel ATX 12V v3.1 form factor motherboards and cases.
- Supports PCIe Gen 5.1 graphics cards via native 16-pin (12+4 pin) connector, delivering up to 450W — including GeForce RTX 50 Series GPUs.
- Full-range AC input (100–240V) makes it compatible with mains power in most countries.
- Fits chassis with a minimum PSU clearance depth of 140mm.
- Provides two CPU/EPS 4+4 pin connectors, supporting dual-CPU or HEDT boards, but total system draw must remain within 750W.
- Not suitable for systems whose total power draw exceeds 750W combined across GPU, CPU and all other components.
Best for
- High-end single-GPU builds — the 750W output and native 16-pin cable cover current-generation flagship GPUs, including RTX 50 Series cards, without an adapter.
- Compact or mid-tower builds — the 140mm depth fits cases that reject standard-length PSUs, without sacrificing wattage.
- Quiet, efficiency-focused systems — the semi-passive fan and 90% Gold efficiency suit home-office or media-centre machines where noise and running costs matter.
- Overclocking builds — a single +12V rail with active PFC above 0.9 provides stable, clean power delivery under variable CPU and GPU loads.
- Builders who value clean cable routing — full modular cabling with embossed all-black cables means unused cables are left out entirely.
Trade-offs
- Dual-GPU or multi-GPU workstation builds — only four PCIe 6+2 pin connectors and one 16-pin connector are provided; total system power is capped at 750W.
- Systems requiring more than 8 SATA or 3 peripheral connectors — connector count is fixed by the cable set included.
- Chassis deeper than 140mm PSU bay not an issue, but those shallower than 140mm — the unit's depth means it will not physically fit cases with less than 140mm of PSU clearance.
- Buyers prioritising higher efficiency tiers — this unit is rated Gold (90% at typical load); Platinum or Titanium units achieve higher efficiency at light and full loads.
80 Plus Gold certified ensures to deliver 90% efficiency at 50% load. The better power efficiency leads to less power waste, less heat and less fan noise. The single +12V rail delivers optimal power output, stability, and compatibility for hardware, offering the easiest installation of power cables and the ideal design for overclocking.
Leveraging our expertise in heat dissipation and material selection, the power supply is slimmed down to just 140mm, maximizing performance while ensuring compatibility with even the most space-constrained chassis.
Ready for next-gen power demands, this ATX 3.1 compliant PSU handles up to 3× GPU and 2× system power excursions with 70% efficiency at low loads. The high-performance native 16-pin cable delivers up to 450W for PCIe Gen 5.1 graphics cards, such as the GeForce RTX™ 50 Series and beyond.
Carrying the Ultra Durable design DNA, this power supply packs high-quality components and smart design features for rock-solid stability and lasting performance. High-quality Japanese capacitors are used throughout, ensuring efficient performance and long-lasting reliability. Fan speed adjusts automatically based on power load, staying silent when the system is idle or under 20 percent load. The hydraulic bearing fan ensures a longer, more stable lifespan for sustained performance.
Multiple protection features are integrated to ensure stable operation under any condition.
