The CORSAIR RM850x SHIFT is an 850W fully modular ATX power supply for PC builders who want to power a modern gaming or workstation system. Its side-mounted cable connections can make it easier to reach and manage the PSU cables in a compatible case.

It supports the ATX 3.1 and PCIe 5.1 standards and includes a native 12V-2x6 GPU cable for powering compatible graphics cards. The compact Type-5 modular connectors sit along the side of the unit, while a fan speed control knob and Zero RPM mode let you adjust cooling behaviour. Cybenetics Gold certification, 105°C-rated Japanese electrolytic capacitors and a 10-year warranty round out the design.

Compatibility

Check that your case supports an ATX power supply and has at least 30mm of clearance between the PSU and side panel for the SHIFT connectors. Confirm that your components' power connectors are supported by the supplied cables before installation. Good to know: the side-mounted connections need room beside the PSU, so check case clearance before buying.
