ATX Power Supply for Modern Standby Systems

The KHACHIMO unit is a 500W ATX power supply designed for PCs that use Modern Standby. It delivers 12V and 24V outputs and carries 80 PLUS Gold certification. The platform suits builders who want efficient power conversion and fast wake-from-sleep response in a standard form factor.

Resonant LLC Topology with DC-to-DC Conversion

The internal resonant LLC topology paired with DC-to-DC conversion supplies clean, consistent power and reduces coil whine. This design also enables more energy-efficient sleep states, which benefits daily use by keeping the system quieter and more responsive during low-power intervals.

Zero RPM Fan Mode for Near-Silent Operation

At low and medium loads the cooling fan stops completely, providing near-silent operation. Combined with 80 PLUS Gold efficiency, the unit runs cooler and draws less power during typical workloads. Buyers who need active cooling at very light loads should note the fan remains off until higher demand.

Questions about this item

What does the 80 PLUS Gold rating mean for the 500W unit's efficiency?

The 80 PLUS Gold certification confirms high-efficiency operation across typical loads, reducing power draw, heat output, and fan noise compared to lower-rated supplies.

What physical space and mounting does the ATX form factor require?

The ATX form factor fits standard ATX cases using four rear mounting screws; ensure your chassis has an ATX PSU bay and clearance for the unit's depth.

How is the power supply installed and which step is often missed?

Mount the unit with four screws, connect the 24-pin ATX and CPU power cables to the motherboard, then attach GPU and drive cables; the step often missed is plugging in the CPU 4+4-pin connector near the socket.
