Virtalähde Cooler Master X Silent Edge Platinum 1100 W 24-pin ATX musta

Power supply unit Cooler Master X Silent Edge Platinum 1100 W is a fanless ATX PSU designed for quiet desktop systems. It delivers 1100 W total power with up to 94% efficiency and 80 PLUS Platinum certification. Built with a heat pipe, private aluminum thermal mold, and industrial IC components, the unit supports 200–240 V 50/60 Hz input and uses a 24-pin ATX motherboard connector. The black housing includes modular cabling with multiple SATA cable lengths and a reinforced 90° 12V-2×6 connector compatible with ATX 3.1 for reliable GPU power delivery.

Advantages

The fanless design eliminates moving parts and dust intake, providing near-silent operation suitable for noise-sensitive environments. Proprietary heat dissipation features — including an aluminum thermal mold and heat pipe thermal technology — maintain uniform temperature across components to improve efficiency and extend lifespan. An Active Bridge Rectifier with Infineon CoolMOS increases power conversion efficiency by about 2% compared with traditional diodes, reducing power loss. Modular cabling reduces clutter and the ATX 3.1–compatible 90° 12V-2×6 connector supports up to 600 W to the GPU for stable, durable connections.

Suitable for

• Silent or noise-sensitive desktop systems
• High-performance gaming rigs requiring stable GPU power
• Workstations and home offices where reliability and thermal control are important

How to use

Install the Cooler Master X Silent Edge Platinum into a compatible ATX chassis following the motherboard and PSU manufacturer instructions. Connect the 24-pin ATX cable to the motherboard and attach required PCIe, SATA and peripheral cables using the modular connectors. Ensure the reinforced 90° 12V-2×6 connector is properly seated when connecting high-power GPUs. Use appropriate input voltage (200–240 V) and verify that system grounding and case airflow meet safety guidelines even for fanless operation.

Recommendations

For optimal longevity and performance, allow adequate case ventilation despite the fanless design, avoid placing the unit in fully enclosed or poorly ventilated spaces, and ensure dust accumulation is checked periodically since passive cooling relies on free airflow.
