The Sharkoon Rebel P20 1000W in white is a fully modular ATX power supply built for high-end gaming PCs and white-themed builds running a modern graphics card and a many-core CPU. Supplied under part number 4044951042425, it is ATX 3.1 and PCIe 5.1 ready with a 12V-2x6 connector for the latest GPUs, and its 80 PLUS Gold rating plus Cybenetics Platinum certification deliver excellent efficiency with low heat.

Before you buy — fit & compatibility
This is a standard ATX-format, fully modular unit with a space-saving 140 mm depth that fits most mid-tower and many compact cases. The 12V-2x6 cable powers modern ATX 3.1 / PCIe 5.1 graphics cards directly; older cards use the included 8-pin PCIe cables. The white finish suits light-themed showcase builds.

Frequently Asked Questions

Does the Rebel P20 1000W work with the latest GeForce RTX cards?
Yes. It is ATX 3.1 and PCIe 5.1 ready with a 12V-2x6 (12+4 pin) connector — the current power cable for modern high-end GPUs — so you can connect one directly without adapters.
Is 1000W enough for my build?
For the vast majority of single-GPU systems, yes — 1000 W comfortably powers a high-end graphics card alongside a many-core CPU, with headroom for storage, cooling and moderate overclocking.
Is the Rebel P20 fully modular?
Yes. Every cable detaches, including the 24-pin, so you only install the cables your build needs for cleaner cable management and better airflow — ideal in a white showcase build.
What does Zero RPM mode do?
Zero RPM mode keeps the 120 mm fan switched off during low and medium loads, making the power supply effectively silent for everyday use; the fan only spins up under heavier load.
Singular Expert Insight
The white Rebel P20 1000W is an affordable way to bring serious power into a clean, light-themed build: it brings ATX 3.1, a 12V-2x6 cable, Cybenetics Platinum efficiency and Zero RPM silence in a compact 140 mm body, at a price well below premium-brand units. 1000 W is the sweet spot for a high-end single-GPU build; step up to the 1200 W model if you run a flagship 500 W-plus card. 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 high-end build.

Buyer’s Guide

Buy it if
You want an affordable, quiet 1000 W unit with ATX 3.1, a 12V-2x6 cable and Cybenetics Platinum efficiency in a clean white finish for a high-end build.
Skip it if
You prefer a black PSU, run a flagship 500 W-plus GPU (choose the 1200 W model), or need a longer manufacturer warranty.
Also consider
The 1200 W Sharkoon Rebel P20 White for more headroom, or the black Rebel P20 1000W for non-themed builds.
