CORSAIR napájací zdroj - 850W RMe séria RM850e 24-pin ATX čierny

The CORSAIR RM850e 850 W is a fully modular ATX power supply designed for modern desktop PCs. It delivers 850 watts of continuous power, includes a native 12V-2x6 (PCIe 5.1) GPU connector, and is ATX 3.1 certified with Cybenetics Gold efficiency for reliable, energy-efficient operation. The unit has a compact 140 mm length, a 120 mm fan for active cooling, a 24-pin ATX motherboard connector and a black finish that fits most builds.

Advantages

The RM850e combines fully modular cabling for neat builds with native PCIe 5.1 12V-2x6 GPU support, enabling compatibility with current and next‑gen graphics cards. ATX 3.1 certification and 80 PLUS Gold / Cybenetics Gold efficiency provide stable power delivery with up to around 90% efficiency, lower noise and cooler temperatures. A compact 140 mm housing and a 120 mm rifle-bearing fan reduce space requirements and keep acoustic output low. Industrial-grade components, including resonant LLC topology with DC-DC conversion and 105°C rated capacitors, ensure long-term reliability and consistent electrical performance.

Suitable for

• High-performance gaming PCs using modern GPUs
• Workstations requiring stable 850 W power delivery
• Compact ATX cases where shorter PSU length is needed
• Systems that benefit from fully modular cabling for improved airflow and cable management
