About the item:

  • PCIe 5.0 / 12VHPWR native support — includes a native 16-pin (12VHPWR) cable capable of delivering up to 600 W for modern graphics cards.

  • ATX 3.x / ATX 3.0 compatibility with power excursions — handles transient spikes per the Intel ATX 3.0 standard, ensuring stable output during load surges.

  • 80 Plus Gold efficiency — achieves ≥90% efficiency at typical loads, reducing wasted power, heat, and fan noise.

  • Fully modular cable design with compact form factor — only needed cables are used, improving airflow and flexibility; PSU dimensions are kept reasonable for easier integration.

  • High-quality components & protection suite — uses Japanese capacitors, enhanced heatsink area, a 120 mm smart hydraulic (HYB) fan with fan-stop behavior under low load, and multiple protections (OVP, OPP, SCP, UVP, OCP, OTP).

Supporting the latest PCIe 5.0 / 12VHPWR standard and compliant with ATX 3.x / ATX 3.0 transient requirements, it provides a robust foundation for gaming rigs, creator systems, and high-end workstations.

With a fully modular design, 80 Plus Gold certification, and advanced protections, the UD850GM offers both flexibility and reliability.

Its compact footprint and smart cooling system make it suitable for builds where space, airflow, and performance stability are all critical.
