SKU CH-VZ50-JA4J9

  • Product typeATX
  • Faster wake from sleep with Modern Standby support

  • Silent operation at typical loads via Zero RPM fan mode
  • Clean, stable power delivery using resonant LLC and DC-to-DC topology
  • Reduced coil whine for quieter system performance

250W ATX power supply for compact PCs

This new KHACHIMO BTX a4800c unit delivers 250 watts through a standard ATX form factor and carries 80 PLUS Gold certification for efficient power conversion. It is built for small-form-factor desktops and workstations that require reliable, low-noise energy delivery.

Ideal for office builds and quiet workstations

Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency, while the Zero RPM fan mode stops the fan entirely at light loads for near-silent operation. Builders needing higher wattage for discrete graphics cards or multi-drive arrays should look elsewhere.

250 watt rated output defines the use case

The resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine, but the fixed 250W ceiling means this supply only suits systems whose total draw stays within that limit.
