GIGABYTE GP-UD750GM PG5 V2 ICE 750W 80 Plus Gold ATX 3.1 PSU
The GIGABYTE GP-UD750GM PG5 V2 ICE 750W is a fully modular ATX 3.1 power supply designed for builders who need reliable, next-generation GPU compatibility without compromising on silence or stability. It suits system builders pairing a high-end PCIe Gen 5.1 graphics card — including GeForce RTX 50 Series — with a mid-to-high-end platform, and those who want a quiet, self-regulating fan that only spins up when needed.
Why this product
ATX 3.1 and PCIe Gen 5.1 ready
It includes a native 16-pin cable capable of delivering up to 450W, making it compatible with the latest high-power GPUs such as the GeForce RTX 50 Series without adapters.
80 PLUS Gold certified efficiency
It achieves 90% efficiency at typical load, with 70% efficiency retained even at low loads — reducing wasted heat and keeping electricity consumption in check.
Smart fan stays silent at low loads
The 120mm hydraulic bearing fan adjusts speed automatically based on load, remaining completely passive below 20% load for near-silent operation during light tasks or idle states.
100% Japanese capacitors throughout
Every capacitor is sourced from Japanese manufacturers, which the vendor states supports long-term reliability and stable power delivery across the unit's lifespan.
Six-layer protection suite built in
It integrates OVP, OPP, SCP, UVP, OCP and OTP protections, guarding connected components against overvoltage, overcurrent, short circuits and thermal faults.
Fully modular, all-white embossed cables
Every cable is detachable, so unused connectors stay out of the case entirely. The embossed all-white cable set is designed to suit white or light-themed builds.

- Compatible with Intel ATX 12V v3.1 motherboards and cases — fits the standard ATX form factor at 150 × 140 × 86 mm.
- Works with PCIe Gen 5.1 graphics cards including the GeForce RTX 50 Series via the native 16-pin (12+4) connector supplying up to 450W.
- Accepts full-range AC input from 100–240V at 60–50 Hz, making it suitable for use in most countries worldwide.
- Provides 8 SATA connectors and 4 PCIe 6+2 pin connectors, covering most mid-range to high-end multi-drive and multi-GPU configurations.
- Only one 16-pin PCIe connector is included; builders needing more than one high-power GPU connection will need additional adapters or a higher-tier unit.
- Supports up to 3× GPU power excursions and 2× system power excursions as per ATX 3.1 spec — confirm your GPU's peak excursion demands before pairing with a card rated above 450W sustained.
Best for
- High-end single-GPU builds — the native 16-pin cable and 750W output are well matched to PCIe Gen 5.1 cards drawing up to 450W on the GPU rail.
- Quiet, low-noise builds — the fan stays off below 20% load, so the unit runs silently during everyday desktop use or light gaming.
- White or light-themed cases — the all-white embossed modular cables are designed to complement bright builds without the need for cable sleeving.
- Compact ATX cases — at 140mm depth it is shorter than many 750W units, suiting cases with tighter PSU clearance.
- Builders prioritising longevity — 100% Japanese capacitors, a hydraulic bearing fan and an MTBF rating above 100,000 hours indicate the vendor's durability focus.
Trade-offs
- Dual high-power GPU configurations — only one 16-pin connector is provided, limiting native support to a single PCIe Gen 5.1 card.
- Very high-wattage systems above 750W sustained — the output capacity is fixed at 750W; heavily overclocked platforms or multi-GPU rigs needing more headroom should look at higher-wattage units.
- Builds requiring non-ATX form factors — it is an ATX 12V v3.1 unit and will not physically fit SFX, SFX-L or TFX chassis.
- Legacy peripheral-heavy setups needing many Molex connectors — only three 4-pin peripheral connectors and one floppy connector are provided on a single cable chain.
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.
