SKU CH-MZPS-VEVK0

ATX power supply delivering 240 W with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby support

  • TypeATX
  • Faster wake-from-sleep with Modern Standby support

  • Silent low-load operation through Zero RPM fan mode
  • Clean, stable power delivery from resonant LLC with DC-to-DC conversion
  • Reduced coil whine for quieter overall system noise

240W ATX power supply for compact builds

The KHACHIMO SP807 delivers 240 watts of continuous power in a standard ATX form factor. It is suited to small-form-factor desktops, office workstations and low-power home servers that do not require auxiliary GPU connectors. The 80 PLUS Gold certification confirms high efficiency across typical load ranges. Builders needing more than 240W or dedicated graphics power should look elsewhere.

80 PLUS Gold efficiency with Zero RPM fan mode

At low and medium loads the cooling fan stops completely, providing near-silent operation for quiet environments. The Gold-rated design reduces waste heat, lowering overall system temperatures and power draw during everyday tasks. Resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight and minimises coil whine. Modern Standby compatibility enables extremely fast wake-from-sleep transitions.

Modern Standby support and quiet topology

Modern Standby compatibility allows the supply to enter and exit low-power sleep states quickly, improving responsiveness in supported operating systems. The resonant LLC and DC-to-DC architecture reduces electrical noise and supports deeper, more efficient sleep states. Zero RPM fan mode activates automatically without software configuration. No additional cables or adapters are mentioned in the specifications.

Questions about this item

How do I install the ATX power supply and what step do people often miss?

Mount the unit in the case using the four ATX screw holes, connect the 24-pin motherboard and CPU power cables, then verify the power switch on the rear is set to on before pressing the case button.

What maintenance will the 80 PLUS Gold unit need later?

Use compressed air to clear dust from the fan grill and intake vents every six to twelve months; the Zero RPM mode means the fan spins less, so dust builds up more slowly.

Which limit appears first during sustained high load on the 240W supply?

The 240 watt total output ceiling is reached before thermal limits, triggering over-power protection if the system draws more than the rated capacity.
