KHACHIMO ATX Power Supply 48V 300W 80 PLUS Gold

SKU CH-P8W7-7JM6F

An ATX unit delivering 48 V at 300 W with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby support

  • TypeATX
  • Faster wake-from-sleep with Modern Standby support
  • 80 PLUS Gold efficiency cuts power use and heat
  • Fan stays off at low loads for silent running
  • Resonant LLC topology with DC-to-DC delivers clean, stable power
  • 48 V 300 W ATX output for compatible systems

Target system compatibility

This 48 V ATX power supply delivers 300 W and carries 80 PLUS Gold certification. It is built for systems that require a 48 V input and benefit from high-efficiency operation, low-load stability and quiet running.

Setup requirements

Verify that your hardware accepts a 48 V ATX input and that the total system draw stays within the 300 W rating. Ensure the chassis has room for a standard ATX unit and that the motherboard supports Modern Standby to use the fast wake and low-load efficiency features.

Upgrade context

The unit replaces older 48 V supplies that lack Gold efficiency, Zero RPM fan mode or resonant LLC topology with DC-to-DC conversion. The jump is worthwhile when you need quieter operation at low loads, reduced coil whine and support for deeper sleep states.

Perguntas sobre este artigo

Does the unit ship with cables and mounting screws or must they be purchased separately?

The power supply comes as the unit only; standard ATX power cables and case mounting screws are not included and must be sourced separately.

Should I choose the 48 V 300 W model or a different voltage version for a TDK-Lambda SWS300A replacement?

The 48 V 300 W unit matches the SWS300A-48 specification exactly; select this version when your equipment requires a 48 V output at up to 300 W.

What does the 80 PLUS Gold rating mean for everyday efficiency and noise?

80 PLUS Gold certifies high efficiency at typical loads, reducing power draw and heat so the Zero RPM fan mode can stay off longer during quiet operation.
