500W ATX Power Supply for Modern Standby Systems

The KHACHIMO M1S-3501V is a 500W ATX power supply built for modern desktop builds. It carries 80 PLUS Gold certification for high efficiency across typical loads. A resonant LLC topology with DC-to-DC conversion delivers clean, consistent power to components. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency.

Suitable for Efficient Quiet Builds Not

This unit suits builders who want efficient, quiet operation in a standard ATX chassis. The Zero RPM fan mode stops the fan completely at low and medium loads for near-silent running. The topology reduces coil whine and supports deeper sleep states. Systems requiring multiple high-end graphics cards or sustained loads well beyond 500W should look at higher-capacity units.

80 PLUS Gold Efficiency Decides Fit

The single specification that decides fit is the 80 PLUS Gold efficiency rating. It guarantees high efficiency operation for lower power consumption, less noise, and cooler temperatures under typical loads. If your build demands that efficiency tier for lower electricity costs or thermal headroom, this supply meets it. If a lower efficiency rating is acceptable, other options exist.
