Gigabyte GAMING 850GM PG5 850W ATX 3.1 80+ Gold Power Supply

The Gigabyte 850GM PG5 is a fully modular 850W unit aimed at modern gaming PCs. It is built to the ATX 3.1 standard with PCIe 5.1 compatibility and is designed to provide steady power for desktop systems and graphics cards with demanding power needs.

Power & efficiency

The unit supplies 850W with 80 PLUS Gold certification and is additionally rated Cybenetics ETA Platinum and LAMBDA A+. That mix of ratings points to efficient power conversion with less wasted heat, making it a fit for a gaming build or a capable desktop. It is worth confirming the unit's compatibility with your components before installation.

Cables & connectors

The design is fully modular and lets you attach only the cables you need for cleaner cable management inside the case. The unit includes a built-in 12V-2x6 connector for compatible graphics cards, alongside support for PCIe 8-pin connections for cards that do not use the newer connector.

Reliability & cooling

Cooling is handled by a 135mm Smart Fluid Dynamic Bearing fan for quiet airflow, combined with HybridCool Smart Fan Control that adjusts fan behaviour according to load and internal temperature. The protection set covers OVP, OPP, SCP, UVP, OCP, OTP, NLO and SIP, guarding against abnormal voltage, current, load and temperature.
