Gold efficiency and quiet operation at 40 °C

80 PLUS Gold certification confirms up to 91 % efficiency during typical loads, reducing waste heat and electricity draw. A 120 mm rifle-bearing fan with grooved blades runs at an A- Cybenetics noise rating, keeping acoustics low even under sustained demand. The main capacitor is rated for 105 °C, and the unit maintains full output at 40 °C ambient temperature. Platinum Cybenetics efficiency rating applies to this 850 W model.

Fully modular cables simplify cable management

Every cable detaches from the unit, so only the required leads stay inside the chassis. The single 12+4-pin cable connects directly to PCIe 5.1 graphics cards without adapters, eliminating extra junctions that can affect signal quality. Japanese 105 °C main capacitors improve long-term reliability under high thermal stress. No additional software or accessories are bundled.
