ATX 3.0 power delivery

This fully modular ATX 3.0 power supply provides 850 W of continuous output with 80 Plus Gold efficiency. It includes a native 16-pin PCIe Gen 5.0 cable for modern graphics cards and uses dual ball-bearing fan technology for extended lifespan. The compact 150 mm depth fits most standard cases.

Suited for single-GPU builds.

Builders assembling a system with one high-end GPU and a modern CPU will find the two CPU 4+4-pin connectors and single 16-pin connector convenient. Systems that require two or more 16-pin connections, or more than three 8-pin PCIe cables, should look at a higher-wattage unit with additional native connectors.

Native 16-pin PCIe Gen 5.0 connector included

The bundled 16-pin cable plugs directly into PCIe Gen 5.0 graphics cards without adapters, satisfying the ATX 3.0 power-excursion requirements. If your graphics card uses only traditional 8-pin inputs, the package also supplies a 16-pin-to-dual-8-pin cable and a separate 1-to-1 8-pin cable.
