Support PCIe Gen 5.0 graphics card
The UD850GM PCIE 5.0 has a 16-pin connector and comes with a high-quality native 16-pin cable that allows you to use the PSU with a PCIe Gen 5.0 graphics card. This cable can support up to 600 watts of power to the graphics card.

ULTRA DURABLE
Inherit the product design spirit of GIGABYTE Ultra Durable, thus introducing a variety of high-quality materials and designs. Ultra Durable combines high-quality main Japanese capacitors, enhanced thermal solution, 120mm smart hydraulic bearing (HYB) fan, and six circuit protection designs. It provides consumers with a high-quality and stable power supply, and can be used for a long time.

HIGH QUALITY JAPANESE CAPACITORS
The main capacitors use high quality Japanese capacitors to produce the efficient performance and ensure the longer reliability.

ENHANCED THERMAL SOLUTION
Compared with the standard thermal solution, we have enlarged the heatsink by about 200% or more, and optimized the airflow. The heat dissipation performance is increased by more than 10%, thus prolonging the service life of the components.

120MM SMART HYDRAULIC BEARING (HYB) FAN
The fan speed is adjusted according to the automatic power detection and stops when the system is idle or under low load (less than 20% load). The hydraulic bearing fan provides longer and more stable life time.

PROTECTION
In order to make sure the entire computer system to operate stably under any conditions, we not only added protection designs such as OCP, OTP, OVP, OPP, UVP and SCP, but also ensured the stable operation of your system through the safety certification of various countries.

FULLY MODULAR DESIGN
All the black flat cables are modular design. Installing only the cables you need to reduce clutter, to increase the airflow and to improve the chassis thermal performance.

80 PLUS GOLD CERTIFIED
80 Plus Gold certified ensures to deliver 90% efficiency at 50% load. The better power efficiency leads to less power waste, less heat and less fan noise.

PLENTIFUL POWER SUPPLY
The +12VHPWR and the +12V can provide a total of 850W power output. The +12VHPWR can provide up to 600W for the latest PCIe Gen 5.0 graphics card.

COMPACT DESIGN
With the help of engineers' excellent design capabilities and heat dissipation technology on various hardware products, and the use of higher quality materials, GIGABYTE has reduced the length of the power supply to an amazing 140 mm, so it can be easily installed in any chassis without space constraints.
