Gigabyte UD850GM Overview
Bring reliable power to PCIe 5.0 graphics cards and more with the UD850GM PG5 850W 80 PLUS Gold Modular Power Supply in white from Gigabyte. Featuring a single +12V rail and utilizing the Intel ATX12V 3.0 specification, this 850W power supply features a 16-pin PCIe connector for up to 600W of power to PCIe 5.0 graphics cards. Four 8-pin PCIe, eight SATA, and three 4-pin connectors are also present, along with a floppy connector for legacy drives. The modular and compact design allows for easy building and optimal airflow and heat dissipation, while a 120mm smart hydraulic bearing cooling fan ensures reliable cooling.
PCIe 5.0 GPU Support
Use the 16-pin PCIe cable to connect to PCIe 5.0 graphics cards and deliver up to 600W of power.
Intel ATX 3.0 Standard
The UD850GM PG5 utilizes the Intel ATX 3.0 standard for up to 200% power excursion support and allowing it to sustain three times the GPU power excursions and twice the total power excursions of previous iterations. Fully compatible with Intel's Power Supply Design Guide (PSDG), the ATX 3.0 standard reaches 70% low load efficiency and complies with required power supply timing standards.
Ultra Durable by Design
Gigabyte's Ultra Durable label denotes quality materials and design, including robust capacitors, enhanced thermal offloading, a 120mm smart hydraulic bearing fan, and six circuit protection designs for stable long-term power.
Robust Capacitors
Robust capacitors ensure efficient and reliable performance.
Enhanced Thermal Offloading
Optimized airflow is achieved via a heatsink that is 200% larger than standard thermal designs, and heat dissipation is increased by more than 10% for a prolonged lifespan of components.
120mm Smart Hydraulic Bearing Fan
The fan speed is adjusted according to the automatic power detection and stops when the system is idle or under less than 20% load, ensuring stable operation for a longer lifespan.
Built-In Protection
Built-in protections ensure stable operation and keep you safe from over-current, over-temperature, over-voltage, over-power, under-power, and short-circuit scenarios.
Fully Modular Design
Install the cables you need and stash the ones you don't the modular design reduces clutter for increased airflow and improved thermal offloading. Plus, the flat black cable design enables easy routing and a clean build.
80 PLUS Gold Certified
80 PLUS Gold certified ensures up to 90% efficiency at 50% load. Higher efficiency means less power waste, heat, and fan noise.
Compact Design
Measuring just 5.5" on its longest side, the UD850GM PG 5 easily installs to a wide range of computer cases.
