KHACHIMO 650W ATX Power Supply YM-2651J PSR650B-12D1

650W ATX PSU with Gold Efficiency

This KHACHIMO power supply delivers 650W of continuous power in a standard ATX form factor. It carries 80 PLUS Gold certification, indicating high efficiency across typical loads. The unit supports Modern Standby for rapid wake-from-sleep transitions and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion ensures clean, consistent power delivery.

Suited for Efficient Mid-Range Builds

Ideal for system builders who prioritise low noise and energy efficiency in a mid-range desktop. The zero RPM fan mode keeps the unit silent during light workloads, benefiting home office or media centre environments. Builders requiring higher wattage for multi-GPU configurations or extreme overclocking should consider higher-capacity alternatives. Those needing modular cabling for compact cases should verify cable management requirements.

Integrates into Standard ATX Systems

Fits standard ATX chassis and provides the necessary connectors for modern motherboards, graphics cards and storage devices. DC-to-DC conversion minimises ripple on minor rails, supporting stable operation of sensitive components. Modern Standby compatibility frees the system to enter deeper sleep states without compatibility issues. High Gold-rated efficiency reduces waste heat, easing the burden on case airflow.
