GIGABYTE UD1000GM PG5 V2 ICE 1000W PSU - ATX 3.1 PCIe 5.1
The GIGABYTE UD1000GM PG5 V2 ICE is a 1000W fully modular ATX 3.1 power supply built for builders who need a PSU that can meet the demanding power requirements of current and next-generation PCIe Gen 5.1 graphics cards, including the GeForce RTX 50 Series. It combines 80 PLUS Gold and Cybenetics Platinum efficiency ratings with a 10-year warranty and a comprehensive set of hardware protections, making it a strong anchor for a high-performance desktop build.
Why this product
Native 16-pin PCIe Gen 5.1 cable
A built-in 12+4 pin cable delivers up to 600W to a single GPU, meeting the full power budget of PCIe Gen 5.1 cards such as the GeForce RTX 50 Series without adapters.
ATX 3.1 compliant for multi-GPU excursions
Intel ATX 3.1 compliance means it can handle up to 3× GPU and 2× system power excursions, preventing shutdowns during sudden workload spikes common with modern discrete graphics.
80 PLUS Gold and Cybenetics Platinum rated
Achieves 90% efficiency at typical load and 70% efficiency at low loads, reducing waste heat and energy costs across the full usage range.
100% Japanese capacitors throughout
Every capacitor is sourced from Japanese manufacturers, which GIGABYTE specifies as the basis for stable voltage delivery and long-term reliability.
Silent at idle and light loads
The 120mm hydraulic bearing fan does not spin until the system exceeds 20% load, keeping the PSU completely silent during everyday desktop use.
10-year product warranty
GIGABYTE backs this unit with a 10-year warranty (subject to region), one of the longest coverage periods available on a consumer power supply.

- The 10-year warranty coverage is subject to regional availability; verify with your local GIGABYTE distributor before purchase.
- Not designed for SFX or TFX form-factor cases; the 140 mm depth exceeds SFX dimensions.
Best for
- High-end GPU builds: delivers up to 600W through a native PCIe Gen 5.1 connector and handles extreme power excursions, making it appropriate for RTX 50 Series and similarly demanding cards.
- Long-term ownership: the 10-year warranty and hydraulic bearing fan are both indicators of an extended service life, reducing replacement risk over a multi-year ownership period.
- Quiet workstations: the fan stays off below 20% load, so everyday desktop and office tasks run in complete silence.
- Energy-conscious builders: dual efficiency certifications (80 PLUS Gold and Cybenetics Platinum) confirm low power waste at both typical and light loads.
- Clean cable management builds: the fully modular design means unused cables are never installed, and all cables are all-black with an embossed finish.
Trade-offs
- Compact or small-form-factor systems: the 150 × 140 × 86 mm body will not fit SFX or TFX PSU bays.
- Very low power systems: at 1000W rated capacity, it is oversized and less cost-effective for builds drawing well under 500W continuously.
- Regions where the 10-year warranty is unavailable: warranty coverage is subject to region, so buyers should confirm local terms before purchasing.
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 600W 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.
