Product Description
The GIGABYTE UD850GM 850W Ultra Durable 80+ Gold Fully Modular Power Supply is a premium, compact powerhouse engineered to supply clean, high-amperage current to modern multi-core processors and transient-heavy performance graphics cards. Built on GIGABYTE’s signature Ultra Durable philosophy, this unit features 100% premium Japanese main capacitors and an enhanced thermal design featuring internal heatsinks expanded by over 200% to maximize operating longevity. Boasting an official 80 PLUS Gold certification, the architecture achieves up to 90% structural efficiency under typical system loads, cutting power bill losses, mitigating waste thermal radiation, and reducing continuous acoustic footprints across demanding configurations.
This unit incorporates a fully modular, low-profile flat black cable matrix, enabling system builders to run only the power tracks their specific configuration demands to minimize case clutter and promote uninhibited case airflow. Thermal extraction is managed by a 120mm Smart Hydraulic Bearing (HYB) fan which automatically downscales rotational parameters based on real-time power sensing, completely shutting down for silent operation when system load drops below 20%. Secured by a heavy-duty six-fold internal safety shielding array (OVP, OPP, SCP, UVP, OCP, OTP) and packed into a space-saving 140mm frame depth that easily fits compact mid-tower enclosures, this desktop asset arrives backed by an official 5-year limited brand warranty.
