Sharkoon Rebel P20 1200W Power Supply

1200W80+ GoldCybenetics PlatinumFully Modular

The Sharkoon Rebel P20 1200W is a fully modular ATX power supply built for high-end gaming PCs running a flagship graphics card and a many-core CPU. Supplied under part number 4044951040643, 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. A compact 140 mm body helps it fit a wide range of cases. Typically in stock with fast delivery across Cyprus.

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.

Best For

✓High-end gaming PCs with flagship GPUs
✓Content-creation and rendering workstations
✓PCIe 5.1 / 12V-2x6 graphics card builds
✓Quiet builds (Zero RPM 120 mm fan)
✓Multi-core CPU + high-power GPU systems
✓Compact cases needing a short PSU

Key Features

 
ATX 3.1 · PCIe 5.1 · 12V-2x6
ATX 3.1 and PCIe 5.1 ready with a 12V-2x6 (12+4 pin) connector that powers the latest graphics cards directly, plus 8-pin PCIe cables for older cards.
 
80+ Gold · Cybenetics Platinum
Certified 80 PLUS Gold with a higher Cybenetics Platinum efficiency rating (around 89% at 230V), so it wastes less energy as heat and runs cooler.
 
Fully Modular Design
Attach only the cables you need for a tidy build with better airflow — every cable, including the 24-pin, detaches.
 
120mm Fan · Zero RPM Mode
A quiet 120 mm fan with semi-passive Zero RPM operation stays off at low and medium loads for near-silent running.

Frequently Asked Questions

Does the Rebel P20 1200W 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 1200W enough for my build?
For virtually all single-GPU systems, yes — 1200 W comfortably powers a flagship graphics card alongside a many-core CPU, with generous headroom for overclocking and future upgrades.
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.
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 Rebel P20 1200W is an affordable way to get serious power and headroom: 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 1200 W units. It is ideal for a flagship single-GPU build or an overclocked system that wants spare capacity. Most single-GPU gamers will not use the full 1200 W and could save with the 1000 W model. 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 1200 W unit with ATX 3.1, a 12V-2x6 cable and Cybenetics Platinum efficiency for a flagship single-GPU or overclocked build.
Skip it if
Your build is a single mid-range GPU (a 850–1000 W unit fits better and costs less), or you need a longer manufacturer warranty.
Also consider
The 1000 W Sharkoon Rebel P20 for most single-GPU builds, or a premium-brand 1200 W unit if a longer warranty matters most.
