Frequently Asked Questions
Singular Expert Insight
The white Rebel P20 850W is an affordable, good-looking choice for a clean single-GPU build: it brings ATX 3.1, a 12V-2x6 cable, 80+ Gold efficiency and Zero RPM silence in a compact 140 mm body, at a price well below premium-brand units. 850 W suits most modern single-GPU systems; if you run a flagship card or want more headroom, step up to the 1000 W or 1200 W models. The main trade-off is a shorter 2-year warranty. Compare wattages across our PC power supplies, or pair it with a new graphics card for a complete build.
Buyer’s Guide
Buy it if
You want an affordable, quiet 850 W unit with ATX 3.1, a 12V-2x6 cable and 80+ Gold efficiency in a clean white finish for a single-GPU build.
Skip it if
You prefer a black PSU, run a flagship 400 W-plus GPU (choose the 1000 W or 1200 W model), or need a longer warranty.
Also consider
The 1000 W Sharkoon Rebel P20 White for more headroom, or the black Rebel P20 850W for non-themed builds.
