The powerful and quiet CORSAIR RM850x SHIFT power supply delivers 850 W of stable output, side-mounted modular connectors for easy cabling, 80+ Gold / Cybenetics Gold certification, and full compatibility with ATX 3.1 and PCIe 5.1 standards. Thanks to the native 12V-2x6 cable, it easily powers modern graphics cards including NVIDIA GeForce RTX, while the quiet 140 mm FDB fan with Zero RPM mode ensures minimal noise.
Take cable management to the next level. The patented side panel with Type 5 modular connectors makes connecting and tidying cables significantly easier, especially in smaller cases. The PSU meets the latest ATX 3.1 and is PCIe 5.1 ready – an ideal choice for high-performance builds and future upgrades.
High efficiency confirmed by 80+ Gold and Cybenetics Gold means lower power draw, less heat, and quieter operation. The internal design with LLC and DC-DC topology and 105 °C Japanese capacitors guarantees reliability and stable voltages even under load. The 140 mm fan with FDB bearings runs virtually silently in Zero RPM mode at low and medium loads; speed can be adjusted manually for better airflow.
Key benefits:
- 850 W of stable output for modern gaming and workstation builds.
- Side-mounted modular connectors for faster, cleaner installation.
- Native 12V-2x6 cable for new GPUs (e.g., NVIDIA GeForce RTX).
- 80+ Gold / Cybenetics Gold – higher efficiency, lower noise and temperatures.
- ATX 3.1, PCIe 5.1 – ready for the latest standards.
- Fully modular Type 5 cabling + flexible PVC cables and low-profile combs included.
- Manually adjustable fan curve and Zero RPM mode for maximum silence.
