Today, we will be taking a look at the Gigabyte UD850GM PG5 power supply. This power supply is Gigabyte’s latest addition to their UltraDurable series, and supports latest ATX 3.0 and PCIe 5.0 standards, and features the new 12VHPWR 16-pin power connector to support all the latest next-gen graphics card, such as Nvidia’s high-end GeForce RTX 40-series.

The UD850GM PG5 is a fully modular power supply that comes with flat power cables, and it’s certified 80 Plus Gold, giving you an extremely high power efficiency.

It also features a powerful +12V single rail at 70.8A giving you a maximum total output of 850W, which is more than enough for most users and gamers out there.

It uses 100% Japanese capacitors for superb reliability and stability, and comes with six circuit protection designs. It also features an enhanced cooling solution using a silent 120mm fan with a smart hydraulic bearing.

At only 140mm in length, the UD850GM PG5 is one of the most compact modular power supply on the market, and it should more than be suitable to most system builders out there.

We are eager to achieve the harmony between technology and sustainability. With the faith, we transformed the roof of Headquarters into a sustainable eco-roof with more than 400 species of plants and animals inhabited in order to reach the balance between work, life and leisure. In 2017, in response to the international Trillion Tree Campaign, we launched “Make Earth Green Again” and called on the society to plant trees. We also developed and applied the world’s first pure rice husk eco-package, which not only became a sustainability milestone in technology industry, but also won international awards such as iF, Red Dot and Good Design. As a gardener of technology and sustainability, we believe that every action is a seed of anticipation and will thrive into a better future.

We’ll be testing the PSU on our test rig which is comprised of an Intel Core i9-13900K, an Asus Strix Z790 motherboard, 32GB of Patriot Viper RGB DDR5-6200 ram, Lexar NM800 Pro 2TB SSD, and a GeForce RTX 3090 graphics card. The total power consumption should be well over 700W+
