GIGABYTE UD1000GM PG5 V2 1000W 80+ Gold PSU ATX 3.1
The GIGABYTE UD1000GM PG5 V2 1000W 80+ Gold PSU ATX 3.1 is a fully modular power supply built for enthusiast and workstation builders who need to run current and next-generation PCIe Gen 5.1 graphics cards without compromise. It meets the Intel ATX 3.1 specification and includes a native 16-pin cable capable of delivering up to 600W, making it a straightforward fit for GeForce RTX 50 Series cards and similar high-draw GPUs. The 10-year warranty and 100% Japanese capacitors are aimed at builders who want long-term reliability rather than a budget stopgap.
Why this product
ATX 3.1 and PCIe Gen 5.1 Ready
It meets the Intel ATX 3.1 specification and includes a native 16-pin connector delivering up to 600W, supporting GeForce RTX 50 Series cards and beyond without adapters.
80 PLUS Gold and Cybenetics Platinum Certified
It carries both 80 PLUS Gold and Cybenetics Platinum efficiency ratings, with 90% efficiency at typical load and 70% efficiency retained even at low loads.
Fully Modular Cable Design
Every cable is removable, so unused connectors stay out of the case entirely — improving airflow and simplifying the build process.
Comprehensive Eight-Protection Suite
It includes OVP, OPP, SCP, UVP, OCP, OTP, NLO and SIP protections to guard components against voltage, current and thermal faults.
100% Japanese Capacitors
All capacitors are Japanese-sourced, a specification associated with stable long-term performance under sustained load.
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 PSU.
- Output Capacity1000W
- Form FactorATX 12V v3.1 (ATX 3.1)
- 80 PLUS RatingGold
- Efficiency (Typical Load)90%
- Native 16-Pin CableYes — up to 600W
- Warranty10 years (subject to region)
- Dimensions150 × 140 × 86 mm
- MTBF>100,000 hours
- SKUGIG-729
- EAN4719331556150
- Compatible with ATX 3.1 and ATX 12V v3.1 motherboard form factors.
- Works with PCIe Gen 5.1 graphics cards including the GeForce RTX 50 Series via the included native 16-pin (12+4 pin) cable at up to 600W.
- Accepts full-range input voltage from 100–240 Vac, making it suitable for use in most countries worldwide.
- Includes dual 4+4 pin CPU/EPS connectors, compatible with high-end motherboards requiring two EPS power feeds.
- At 150 × 140 × 86 mm, it is described as compact, but verify your case's PSU bay depth before purchasing — a 140 mm depth is standard but not universal in small-form-factor cases.
- The 10-year warranty coverage is subject to region — confirm availability for your location before purchase.
Best for
- High-end GPU builds: The native 600W 16-pin connector and ATX 3.1 compliance make it well matched to RTX 50 Series and other PCIe Gen 5.1 cards that draw power in large transient spikes.
- Long-term ownership: The 10-year warranty and Japanese capacitors suit builders who do not plan to replace the PSU when they upgrade the GPU or CPU.
- Multi-GPU or high-peripheral builds: With 8 SATA, 4 PCIe 6+2 pin, and 3 peripheral connectors alongside the 16-pin, it handles a populated case without needing daisy-chain compromises.
- Efficiency-conscious builders: The Cybenetics Platinum rating and 70% efficiency at low loads keep electricity costs down even when the system is idling.
- Clean cable-management builds: Fully modular cabling means only the cables actually used are routed, keeping the interior tidy.
Trade-offs
- Budget-focused builders: A 1000W ATX 3.1 unit with a 10-year warranty and Japanese capacitors sits at the higher end of the market; lower-wattage or shorter-warranty options cost less.
- Builds needing more than four traditional PCIe connectors: It provides four 6+2 pin PCIe cables — multi-GPU configurations beyond that count would need a higher-connector PSU.
- Very compact or SFF cases: The 140 mm depth may exceed the PSU bay in true small-form-factor chassis designed for SFX or SFX-L units.
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.
