Gigabyte UD850GM PG5 850W Power Supply

The Gigabyte UD850GM PG5 delivers 850W of reliable power with ATX 3.0 compliance and full PCIe Gen 5.0 graphics card support. Engineered with high-quality Japanese capacitors and a fully modular cable system, this 80 PLUS Gold certified PSU provides the efficiency and stability required for high-performance gaming and professional workstations.

PCIe Gen 5.0 Ready with Native 16-Pin Cable

Built for next-generation graphics cards, the UD850GM PG5 includes a high-quality native 16-pin connector capable of delivering up to 600W directly to PCIe Gen 5.0 GPUs. This ensures your system is ready for the latest graphics technology without requiring adapters or compromises.

Ultra Durable Construction

Following Gigabyte's Ultra Durable design philosophy, this power supply incorporates premium Japanese capacitors for enhanced reliability and longevity. The enlarged heatsink—approximately 200% larger than standard designs—combined with optimized airflow increases heat dissipation performance by over 10%, extending component lifespan significantly.

Smart Thermal Management

The 120mm Smart Hydraulic Bearing (HYB) fan automatically adjusts speed based on power load detection. Under idle or low load conditions (below 20% load), the fan stops completely for silent operation. This intelligent cooling solution provides stable performance while minimizing noise during everyday computing tasks.

Comprehensive Protection Systems

Six circuit protection designs safeguard your entire system: Over Current Protection (OCP), Over Voltage Protection (OVP), Under Voltage Protection (UVP), Over Temperature Protection (OTP), Over Power Protection (OPP), and Short Circuit Protection (SCP). These safety features ensure stable operation under all conditions.

Fully Modular Cable Design

All flat black cables feature modular connections, allowing you to install only the cables your system requires. This reduces cable clutter, improves airflow within your chassis, and enhances overall thermal performance. The clean cable management contributes to both aesthetics and functionality.

80 PLUS Gold Efficiency

With 80 PLUS Gold certification, the UD850GM PG5 delivers 90% efficiency at 50% load. Superior power efficiency translates to reduced power consumption, lower heat generation, and quieter fan operation—saving energy costs while maintaining peak performance.

Compact 140mm Design

Despite its robust 850W output, Gigabyte's engineering expertise has reduced the PSU length to just 140mm. This compact form factor ensures compatibility with virtually any PC chassis, including smaller cases with space constraints, without sacrificing power delivery or cooling performance.
