Gigabyte UD850GM PG5 850W 80 PLUS Gold Modular Power Supply (White)

The Gigabyte UD850GM PG5 850W is a fully modular power supply designed for modern high-performance desktop builds that demand clean, stable power delivery alongside forward-looking platform compatibility. Finished in white, it is a practical choice for builds using light-coloured cases or aesthetic-forward setups where cable management and colour coordination matter. The unit carries 80 Plus Gold certification, indicating it operates at 87–92% efficiency across typical load ranges, which translates to less heat generated inside your chassis and lower long-term electricity consumption compared to Bronze or Silver rated alternatives. One of its defining features is full support for the Intel ATX 3.0 specification and the PCIe Gen 5.0 native 12+4 pin connector. This means it can power current-generation graphics cards that ship with a 16-pin PCIe 5.0 power header without requiring bundled adapters, reducing potential points of failure and keeping internal cabling tidy. The single +12V rail topology simplifies power distribution to high-current components such as the CPU and GPU. As a fully modular design, every cable — including the 24-pin ATX motherboard cable — is detachable. Builders only route the cables their system actually requires, reducing airflow obstruction and making the interior easier to photograph or service. The five-year warranty reflects Gigabyte's confidence in the unit's component quality and long-term reliability.
