Before you buy — fit & compatibility
This is a standard ATX-format, fully modular unit with a compact 140 mm casing that fits nearly any modern case. The included 12V-2x6 cable powers modern PCIe 5.1 graphics cards directly; older cards use the supplied 8-pin PCIe cables. Zero RPM mode keeps the fan off at low and medium loads for near-silent operation.

Frequently Asked Questions
Singular Expert Insight
The white RM850e is the clean-build pick for a high-end single-GPU system: the latest ATX 3.1 standard, a 12V-2x6 cable, Zero RPM silence and a 7-year warranty in a colour that disappears into a white case. Compared with the black RM850e it is identical bar the finish, so pick whichever suits your build; step up to the 1000 W RM1000e if you run a flagship 450 W-plus GPU. Compare wattages across our PC power supplies, or pair it with a new graphics card for a complete white build.
Buyer’s Guide
Buy it if
You want a quiet, fully modular 850 W unit with ATX 3.1 and a 12V-2x6 cable in a clean white finish for a high-end or themed build.
Skip it if
You prefer a black PSU, or you run a flagship 450 W-plus GPU and want the extra headroom of a 1000 W unit.
Also consider
The black Corsair RM850e for non-themed builds, or the 1000 W RM1000e if you need more wattage for a higher-end GPU.
