## Summary description

The GIGABYTE GP-UD850GM PG5 is an 850W ATX power supply unit with a 20+4 pin connector. It features an active cooling system with a 12 cm fan and is 80 PLUS Gold certified, ensuring high efficiency. The power supply is designed for PCs and has a compact size with dimensions of 150mm width, 140mm depth, and 85mm height. It supports a wide AC input voltage range of 100-240V and comes with SATA power cables of varying lengths.

## Long description

The GIGABYTE GP-UD850GM PG5 is an 850W ATX power supply in black with a 20+4 pin motherboard connector and a compact 140 mm depth. It is 80 PLUS Gold certified and includes a native 16-pin +12VHPWR cable to support PCIe Gen 5.0 graphics cards, delivering up to 600 W to the GPU while providing a total +12V output of 850 W.
Advantages
The unit uses high-quality Japanese main capacitors and an enlarged heatsink design that improves heat dissipation by over 10%. A 120 mm smart hydraulic bearing (HYB) fan manages cooling with automatic speed control and fan stop under low load. Fully modular flat black cables reduce clutter and improve chassis airflow. The power supply integrates multiple protections (OCP, OTP, OVP, OPP, UVP, SCP) and meets international safety certifications. 80 PLUS Gold efficiency ensures about 90% efficiency at 50% load, reducing wasted power, heat and fan noise.
Suitable for
High-performance gaming PCs with PCIe Gen 5.0 graphics cards
Compact ATX builds requiring a short 140 mm power supply
Systems needing stable 850 W total +12V output
Builds where modular cables and improved airflow are desired
Key specifications
Total power: 850 W
Efficiency: 80 PLUS Gold (≈90% at 50% load)
Motherboard connector: 20+4 pin ATX
PCIe power: native 16-pin (+12VHPWR) supplying up to 600 W to GPU
Fan: 120 mm smart hydraulic bearing (HYB)
Dimensions (approx.): 150 mm (W) x 140 mm (D) x 85 mm (H)
Color: Black
AC input range: 100–240 V
How to use
Install the PSU in a compatible ATX chassis, connect the 20+4 pin ATX cable to the motherboard and use only the modular cables required for your components to reduce clutter. Connect the supplied native 16-pin +12VHPWR cable to a compatible PCIe Gen 5.0 graphics card when high GPU power is needed, ensuring connectors are fully seated. Verify AC input and system grounding before powering on and follow chassis manufacturer guidance for orientation and airflow.
Usage recommendations
Use the fully modular cables to keep cable runs short and unobstructed; allow sufficient case airflow around the enlarged heatsink and maintain at least 20% system load for the fan to remain idle when appropriate. Ensure your GPU and other components do not exceed the combined +12V output limits and consult component manuals for connector compatibility.
