## Long description

The GIGABYTE UD850GM PG5W 850 W is a compact ATX power supply designed for desktop PCs that require stable, efficient power delivery. It supports PCIe Gen 5.0 graphics cards via a native 16-pin (+12VHPWR) connector with a cable capable of delivering up to 450 W to the GPU, and complies with the Intel ATX 3.0 (PSDG) power supply standard for transient power excursions and timing. The unit is 80 PLUS Gold certified and integrates high-quality Japanese capacitors, an enlarged heatsink and a 120 mm smart hydraulic bearing fan to balance cooling, noise and longevity.
Advantages
The power supply offers up to 850 W total output with a +12V rail able to deliver the unit's full rated power. Its native 16-pin PCIe Gen 5.0 connector supports high-power modern graphics cards, while ATX 3.0 compliance ensures support for power excursions and required timing specifications. The 80 PLUS Gold certification provides around 90% efficiency at optimal loads, reducing wasted energy and heat. The fully modular flat-cable design reduces clutter and improves case airflow. Built with Japanese main capacitors, an enlarged heatsink and a smart 120 mm HYB fan, the UD850GM PG5W focuses on durability and stable thermal performance.
