Description: Fully Modular ATX Power Supply RM850x SHIFT (EU) Side Connectors: The patented PSU panel features modular, compact Type-5 side connectors, making cable connection and management significantly easier. Native 12V-2X6 GPU Power Cable: Power modern graphics cards, such as NVIDIA GeForce RTX 50 series, with the included 12V-2x6 cable featuring a dual-color connector for visual confirmation of a secure GPU-side connection, ensuring easy and hassle-free power delivery. Cybenetics Gold Certification: Stable power with up to 89% total efficiency, backed by Cybenetics Gold certification for lower energy consumption, quieter operation, and reduced operating temperature. ATX 3.1 Certification and PCIe 5.1 Compatibility: The RMx SHIFT series meets the latest power and connectivity standards, ensuring efficient and reliable performance. The PSU design is based on LLC topology with DC-DC converters and industrial-grade Japanese capacitors rated for 105°C operation. Fully Modular Type-5 Connectors: CORSAIR Type-5 cables take up less space, and combined with the modular design, make cable management easier. Included PVC Cable Kit: Ultra-flexible cable sets simplify cable management, and included low-profile cable combs keep cables organized, providing a clean look and easier installation. Manual Fan Speed Control: Optimize PSU airflow or case cooling by disabling Zero RPM mode and adjusting the quiet profile via the fan control dial to increase fan speed and airflow. 140mm Fan with Dynamic Oil Bearing: The dynamic oil bearing fan with a magnetic hub reduces noise, while Zero RPM mode completely eliminates fan noise at low and medium loads. | Power supply: 850 W | Fan: 14 cm | PFC: None | MOLEX power connectors: 0 | Floppy power connectors: 0 | SATA power connectors: 9 | Number of connectors PATA: 4 | Number of power supply connector 4-pin 12V: 0 | 8-pin 12V power connectors: 0 | Number of power supply connector 4+4-pin 12V: 2 | PCI-E 6-pin power connectors: 0 | Number of power supply connectors PCI-E 6 +2 pin: 2 | PCI-E 8-pin power connectors: 0 | Number of power connectors PCI-E 16-pin Gen 5: 0 | Number of power connectors 12VHPWR: 0 | Number of USB 10p connectors: 0 | MB power connector: 20 + 4 pin | ATX version: 3.1 | Modular power supply: Yes | Form Factor: ATX | Certificates 80+: 80 PLUS Gold | Dimensions: 160 x 150 x 86 mm | Weight: 2.89

How to use

Install the RM850x in a compatible ATX case and connect the 24-pin ATX cable to the motherboard. Use the fully modular Type-5 connectors to attach only the cables required for your build, including the native 12V-2x6 GPU cable for supported graphics cards. Route the included debossed-PVC cables with the low-profile combs for a neat layout. Adjust the fan behavior with the manual fan speed control knob when additional cooling or airflow is required; otherwise allow Zero RPM Mode to operate for near-silent performance at light loads.

Recommendations

For optimal reliability, ensure adequate case ventilation and use the manual fan override only when sustained higher airflow is needed. Verify GPU compatibility with the native 12V-2x6 connector and follow manufacturer instructions when connecting power cables.
