KHACHIMO 15.7V 4A ATX Power Supply 80 PLUS Gold Zero RPM SR92A720

ATX power supply for modern sleep states

This ATX unit targets builders who need a power source that supports Modern Standby for rapid wake times and improved low-load efficiency. The 80 PLUS Gold certification indicates high energy conversion that reduces waste heat and lowers overall consumption. It suits desktop systems where quiet operation and efficient idle behaviour are priorities.

Quiet operation with zero RPM mode

Resonant LLC topology paired with DC-to-DC conversion delivers clean, consistent output while minimising coil whine. The Zero RPM fan mode stops the cooling fan entirely at low and medium loads, enabling near-silent running during typical desktop tasks. This combination supports more energy efficient sleep states without audible distraction.

Limits of the 15.7 V 4 A design

The fixed 15.7 V output rated at 4 A restricts this unit to platforms designed for that specific voltage and current envelope. It cannot serve builds that require standard multi-rail ATX voltages or higher total wattage for discrete graphics cards. Buyers needing broader voltage rails or greater power headroom must select a different supply.
