Product details

The Corsair RM850x Shift power supply delivers 850 watts of reliable power with ATX 3.1 compatibility and 80 Plus Gold certification for high energy efficiency. This fully modular power supply features a unique side-mounted connector panel that simplifies cable management during installation. With a depth of 140 mm, the unit fits into standard ATX cases and provides ample power for high-performance gaming systems and workstations. The 135 mm fluid dynamic bearing fan ensures quiet operation with a zero RPM fan mode at low to medium loads. Japanese 105°C capacitors offer enhanced durability and long-term reliability. The power supply supports modern graphics cards with multiple PCIe 5.0 12VHPWR connectors and provides comprehensive protection against overvoltage, undervoltage, overcurrent, and short circuits. Fully modular cables allow for custom configurations and reduce cable clutter. Compatible with Intel and AMD platforms, this unit maintains stable power delivery even during transient load spikes up to 235 percent of the rated power. The 80 Plus Gold certification ensures up to 90 percent efficiency at typical loads, reducing energy consumption and heat generation. The magnetic bearing fan design contributes to extended lifespan and consistent cooling performance. All cables use a high-quality, sleeved construction for improved aesthetics and durability. The power supply meets international safety standards and includes a comprehensive set of connectors for modern components, including multiple SATA, peripheral, and CPU power connectors.
