Slim 240W ATX power supply for compact builds

The KHACHIMO Slim S01 delivers 240 watts in an ATX form factor, making it suitable for small-form-factor desktops and office systems that require a standard footprint with modest power needs. Its 80 PLUS Gold certification ensures high efficiency across typical loads.

240-watt limit shapes component choices

At 240 watts the unit can reliably run a modern low-power CPU and integrated graphics, but it cannot support a discrete graphics card or multiple high-draw peripherals. Builders must match the total system draw to this ceiling to avoid instability.

Replaces lower-efficiency SFX or flex-ATX units

This supply upgrades older compact PSUs that lack Modern Standby support, Gold-level efficiency or a zero-RPM fan mode. The jump is worthwhile when faster sleep wake, quieter idle operation and reduced heat output are priorities for the build.

Highlights

  • Faster wake-from-sleep with Modern Standby support
  • Lower power draw and heat via 80 PLUS Gold efficiency
  • Near-silent operation at typical loads with Zero RPM fan mode
  • Clean, stable power delivery using resonant LLC with DC-to-DC conversion
  • Reduced coil whine for quieter system performance

Questions about this item

What does the 240 W rating mean for my build?

It sets the maximum continuous power the unit can deliver to all components combined, so the total system draw should stay below that figure.

What does 80 PLUS Gold certification mean in daily use?

It guarantees high efficiency across typical loads, lowering electricity draw, heat output and fan noise compared with lower-rated units.

How does the ATX form factor affect compatibility?

The unit follows the standard ATX layout, so it fits regular ATX cases and connects to mainstream motherboards and peripherals.
