Power supply Sharkoon Rebel P15 650 — 650W, 1x 12‑pin High Power GPU connector, 2x PCIe, modular cables

The Sharkoon Rebel P15 650 is a 650W ATX power supply designed for desktop PCs that require stable power delivery and flexible cable management. It provides a single 12-pin High Power GPU connector alongside two standard PCIe connectors to support current graphics cards that use a dedicated high‑power feed, while modular cables reduce clutter and make system assembly and maintenance easier.

Advantages

The unit delivers 650 watts of continuous power suitable for mid- to high-range single GPU systems, with a dedicated 12‑pin High Power GPU connector to accommodate modern graphics cards without adapters. Modular cabling simplifies installation and improves airflow by allowing only required cables to be connected. The design emphasizes compatibility with ATX cases and common motherboard power layouts, offering stable voltages and connector variety for a broad range of components.

Suitable for

• Gaming desktops with a single high‑power graphics card
• Content creation workstations that require consistent GPU power
• System builders seeking modular cabling for clean cable routing
• ATX chassis with standard power and cooling configurations

Key specifications

• Output power: 650 W continuous
• GPU connectors: 1x 12‑pin High Power GPU connector, 2x standard PCIe connectors
• Form factor: ATX power supply
• Cable type: modular cables for main and peripheral connections
• Cooling: internal fan for thermal management (fan size and speed depend on load)
• Protection features: multiple standard electrical protections for safe operation

How to use

Install the power supply into an ATX-compatible case, secure it with the case screws, and connect the main 24‑pin motherboard power cable and CPU power cable as required by your motherboard. Use the 12‑pin High Power GPU connector to power compatible graphics cards directly; additional PCIe connectors are available for GPUs or other PCIe devices that require separate feeds. Attach only the modular cables you need to improve airflow and avoid obstructing fans or other components. Ensure all connections are fully seated before powering on the system.

Recommendations

For optimal performance, verify that your graphics card supports a native 12‑pin High Power connector and follow the GPU manufacturer’s installation guidelines. Maintain adequate case airflow and avoid running the supply continuously at or near its maximum rated power to extend component lifespan.
