Description
The GIGABYTE UD750GM PG5 V2 is a high-performance 750W power supply unit (PSU) engineered for the next generation of PC hardware. By adhering to the Intel ATX 3.1 and PCIe Gen 5.1 specifications, it natively supports high-power graphics cards via a dedicated 12V-2x6 connector. This 80 PLUS Gold certified unit prioritizes durability through its "Ultra Durable" design philosophy, utilizing premium internal components to maintain stable voltage delivery under heavy gaming or workstation loads.
This product is for:
- PC Builders: Those constructing mid-to-high-end systems who require a compact PSU that fits easily into smaller ATX cases without sacrificing power.
- NVIDIA RTX 40-Series Users: Gamers using modern GPUs that require the 16-pin PCIe 5.1 power connector for direct, adapter-free connectivity.
- Enthusiasts Seeking Longevity: Users who value the 10-year warranty and 100% Japanese electrolytic capacitors for a decade of reliable service.
- Silent System Seekers: Individuals who appreciate the 120mm Hydraulic Bearing (HYB) fan that adjusts speed based on power detection for quieter operation.
- Clean Build Aesthetics: Builders who prefer fully modular, black flat cables to minimize clutter and improve airflow within the chassis.

Operating the UD750GM PG5 V2 reveals a focus on thermal efficiency and noise reduction. The 120mm HYB fan utilizes a smart control system that keeps RPMs low during idle or light tasks, only ramping up when the system demands significant power. The 140mm depth is a significant advantage for cable management, providing extra clearance in the PSU shroud for stowing excess lengths of the flat, flexible cables. This compact footprint does not compromise performance, as the single +12V rail design ensures consistent power delivery to overclocked CPUs and high-TDP graphics cards.
Compared to standard ATX 2.0 or 3.0 power supplies, the UD750GM PG5 V2 is specifically optimized for the transient power spikes common in modern GPUs, meeting the stricter ATX 3.1 voltage regulation standards. While many 750W Gold units use a mix of components, GIGABYTE’s commitment to 100% Japanese capacitors distinguishes it from entry-level Gold PSUs that may use lower-tier alternatives. Its 140mm length also makes it more versatile than larger 160mm or 180mm high-wattage units, fitting into nearly any standard ATX case on the market.
Q&A:
- Does this PSU support the NVIDIA RTX 4090 or 4080? Yes, it includes a native PCIe Gen 5.1 16-pin (12V-2x6) cable capable of delivering the necessary power without external adapters.
- What is the benefit of ATX 3.1 over ATX 3.0? ATX 3.1 introduces the refined 12V-2x6 connector which offers better physical engagement and safety compared to the original 12VHPWR design.
- Is the fan always spinning? The 120mm HYB fan features intelligent power detection; it adjusts speed based on the load, remaining very quiet during low-power usage.
- Can I use my old modular cables with this unit? No, it is highly recommended to only use the included black flat cables to ensure pinout compatibility and prevent hardware damage.
- What does the "Ultra Durable" branding mean? It signifies the use of high-quality materials, such as Japanese capacitors and an enhanced thermal solution, to extend the product's lifespan.
