The Gigabyte GP-UD850GM is an 850W power supply unit designed for modern computer systems. It holds an 80 PLUS Gold certification, indicating up to 90% efficiency under typical loads, which helps reduce heat output and energy consumption. The unit employs Active Power Factor Correction (PFC) to ensure stable and consistent power delivery to all connected components. Its standard ATX form factor and 140mm depth provide broad compatibility with a majority of mid-tower and full-tower PC cases.
This PSU features a fully-modular design, allowing users to connect only the necessary cables for a cleaner build and improved airflow. All included cables are flat and finished in black, facilitating discreet routing within the chassis. A 120mm hydraulic bearing fan manages thermal performance with a focus on longevity. For component safety, the power supply is equipped with a full suite of protections, including Over Voltage, Over Power, Short Circuit, Under Voltage, Over Current, and Over Temperature Protection.
