This latest iteration is perfect for builders and gamers seeking a dependable power foundation for their systems, including those featuring the newest graphics cards and processors.

It features a native 12V-2x6 GPU power connector, capable of supplying up to 450W to your high-end graphics card without the need for adapters. This forward-thinking design guarantees full compatibility and performance, ready for the likes of NVIDIA's RTX 50 Series and beyond. With a Cybenetics Gold certification, this power supply demonstrates exceptional efficiency, which translates into reduced energy consumption, cooler operating temperatures within your system, and an overall quieter computing experience.

Its low-noise profile is enhanced by a 120mm rifle bearing fan with a precisely calibrated fan curve, ensuring minimal fan noise even under load. For true silence during light tasks, the RM850e (2025) also supports Zero RPM Fan Mode, completely ceasing fan operation when cooling isn't actively needed. Constructed with industrial-grade, 105°C-rated capacitors and employing a robust resonant LLC topology with DC-DC conversion, the RM850e provides consistent, reliable power and electrical performance.

Its fully modular cabling system allows for an impeccably clean and organised build, as you connect only the cables your system truly requires, improving internal airflow and overall aesthetics. The remarkably compact 140mm long casing ensures an easy fit into any modern enthusiast PC case, offering ample room for cable management. Additionally, this unit fully supports Modern Standby, enabling fast wake-from-sleep times and improved efficiency at low power states.
