## Long description

The GIGABYTE GP-UD850GM PG5 850 W is an 850 W ATX power supply unit designed to deliver stable power for desktop PCs. It includes a native 16-pin +12VHPWR cable for compatibility with PCIe Gen 5.0 graphics cards (supports up to 600 W to the GPU), a 120 mm smart hydraulic bearing fan, and 80 PLUS Gold efficiency to reduce wasted power and heat. The unit features a fully modular black flat-cable design, multiple protection mechanisms, and a compact 140 mm length for flexible chassis installation.
Advantages
The PSU uses high-quality Japanese main capacitors and an enlarged heatsink for improved reliability and at least a 10% increase in heat dissipation versus standard solutions. A 120 mm HYB fan adjusts speed automatically and stops at low loads to lower noise and extend fan life. The modular flat cables reduce clutter and improve internal airflow while the 80 PLUS Gold certification ensures around 90% efficiency at typical loads. Multiple protections (OCP, OTP, OVP, OPP, UVP, SCP) and international safety certifications support stable system operation.
Suitable for
 Gaming PCs with PCIe Gen 5.0 graphics cards
 High-performance workstations requiring stable 850 W power delivery
 Small or mid-tower cases that need a compact 140 mm PSU
 Systems where modular cabling and improved airflow are preferred

How to use
Install the GP-UD850GM PG5 into a compatible ATX chassis using standard PSU mounting points. Connect the 20+4 pin ATX cable to the motherboard, attach CPU, SATA, Molex and PCIe connectors as required for your components, and use only the modular cables needed to minimize clutter. For PCIe Gen 5.0 graphics cards, plug the included native 16-pin +12VHPWR cable directly into the GPU. Ensure the AC input matches the local mains (100–240 V, 50–60 Hz) before powering the system.
Usage recommendations
To maintain performance and longevity, keep airflow around the PSU unobstructed, clean dust from the fan and vents periodically, and avoid continuous operation at maximum load. Use the modular cables provided to route cables neatly and verify that the GPU power draw does not exceed the 600 W supported by the +12VHPWR connector.
