GIGABYTE UD850GM 850W Ultra Durable 80+ Gold Full Modular Power Supply

The GIGABYTE UD850GM is a high-quality, 850-watt power supply designed for desktop PCs, offering a potent combination of reliability, efficiency, and compact engineering. Built around GIGABYTE’s “Ultra Durable” philosophy, it incorporates premium Japanese capacitors, an enhanced thermal structure featuring a heatsink enlarged by 200%, and a 120 mm smart hydraulic bearing (HYB) fan that intelligently adjusts airflow and halts when the load drops below 20%, thereby extending its operational lifespan and minimizing noise. This fully modular PSU streamlines cable management by allowing users to connect only the cables they need, improving internal airflow and reducing clutter. As an 80 PLUS Gold-certified unit, the UD850GM delivers approximately 90% efficiency at 50% load, resulting in lower heat production and quieter cooling. It employs a single +12 V rail to provide clean, stable power—ideal for gaming rigs and overclocked systems—with support for Intel’s ATX12V v2.31 specifications. Despite its robust internal build, the PSU remains impressively compact at approximately 140–150 mm in length, fitting a broad range of PC cases. In terms of safety, the UD850GM offers comprehensive protection: OVP, OPP, OCP, UVP, SCP, and OTP. It also features active Power Factor Correction (PFC), over 100,000 hours MTBF, a Power Good signal delay of 100–150 ms, and hold-up time exceeding 16 ms. Connectivity is generous and versatile—this PSU includes a 20+4-pin ATX main cable, two 4+4 EPS CPU power connectors, four PCIe 6+2 connectors, eight SATA power plugs, multiple Molex connectors, and even a floppy power line—all via flat, modular cables to simplify routing. Overall, it’s a well-balanced choice offering efficiency, durability, and space-saving design for both mid-range and high-performance PC builds.

Features of GIGABYTE UD850GM 850W Ultra Durable 80+ Gold Full Modular Power Supply

• Ultra Durable Build: Incorporates premium Japanese main capacitors, an enhanced thermal design with a heatsink enlarged by approximately 200%, and a 120 mm smart hydraulic bearing (HYB) fan that adjusts fan speed based on load and stops entirely during idle or low-load conditions—offering improved cooling efficiency and longer longevity.
• Comprehensive Protection Suite: Equipped with six layers of circuit protection: OVP (Over-Voltage), OPP (Over-Power), SCP (Short-Circuit), UVP (Under-Voltage), OCP (Over-Current), and OTP (Over-Temperature). These ensure system stability and safety under varying conditions.
• 80 PLUS Gold Efficiency: Gold certification ensures around 90% efficiency at 50% load, resulting in reduced heat generation, lower power waste, and quieter operation.
• Fully Modular Design: Features black, flat modular cables so you can use only what's needed, aiding in cleaner builds and improved airflow.
• Single +12V Rail: Offers robust, stable power delivery with a single +12V rail, ideal for overclocking and ensuring compatibility with demanding hardware.
• Compact Form Factor: Measuring just around 140 mm in length, its compact size makes it easy to fit into most PC cases—even those with limited internal space.
