GIGABYTE UD850GM PG5 80+ Gold Fully Modular ATX 3.0 Power Supply

The Gigabyte UD850GM PG5 is an 850-watt fully modular ATX 3.0 power supply built for high-performance desktop systems, including those running PCIe Gen 5.0 graphics cards. Carrying an 80 PLUS Gold certification, it delivers up to 90% efficiency at typical load, meaning less energy is wasted as heat and your electricity costs stay lower during extended sessions. One of the standout features is the native 16-pin (12+4 pin) PCIe 5.0 cable, which can deliver up to 600 W directly to a compatible GPU — eliminating the need for adapter cables and reducing potential failure points at the connector. The fully modular cable system means you only attach the cables your build actually requires, keeping the interior tidy, improving airflow, and making future upgrades easier. Cooling is handled by a 120 mm hydraulic bearing (HYB) fan that adjusts speed automatically based on system load. Under low or idle conditions (below approximately 20% load), the fan can stop entirely, keeping noise levels minimal during light workloads. The enhanced heatsink design — significantly enlarged versus a standard thermal solution — helps dissipate heat more effectively, supporting the rated Mean Time Between Failures (MTBF) of over 100,000 hours. Reliability is reinforced by Japanese-made primary capacitors and a comprehensive protection suite covering over-voltage (OVP), over-power (OPP), short-circuit (SCP), under-voltage (UVP), over-current (OCP), and over-temperature (OTP) conditions. A 5-year warranty (subject to regional terms) further underlines Gigabyte's confidence in the build quality. The compact 150 × 140 × 86 mm body fits standard ATX cases while leaving room for clean cable routing. Active PFC (>0.9 typical) ensures compatibility with universal input voltages from 100 V to 240 V at 50–60 Hz, making this PSU suitable across different regional power grids.
