Giving you ample connectivity options, thermal enhancements, and electrical protections, this power supply backs your high-end components so you can game with piece of mind.

The UD1000GM PG5 operates on the Intel ATX12V standard, delivering 1000W of power via single +12V rail, making this ideal for a wide range of gaming focused components. Use only the cables you need with the modular design, saving space within your case. Flat, low-profile cables make wire management and organization easier, allowing you to easily snake wires through any potentially tight areas. High-quality Japanese capacitors balance and drive power to your components while ensuring up to 90% efficiency at typical load, designating this PSU with an 80 PLUS Gold certification.

80 PLUS Gold Certified

Designed to produce up to 90% efficiency at typical loads, the UD1000GM PG5 is 80 PLUS Gold certified, ensuring a typical electrical load is properly managed.

16-Pin PCIe Gen 5.0 Graphics Card Connector

The UD1000GM PG5 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.

Thermal Conditioning

Keeping the internals safe during heavy loads is an enlarged heatsink and a 120mm smart hydraulic bearing fan, working together to provide you with a long-lasting system. If the current load is less than 20%, the fan stops, adding to the lifespan of the fan.


Designed for stability, Gigabyte added protection designs such as OCP, OTP, OVP, OPP, UVP, and SCP, ensuring proper operation of your system.

Compact Design

Gigabyte reduced the length of the power supply so it can be easily installed in any chassis without space constrictions.
