KHACHIMO 48V 80W ATX Power Supply

SKU CH-MJ0T-653RF

ATX power supply delivering 48 V at 80 W with 80 PLUS Gold efficiency, zero-RPM fan mode and resonant LLC topology for quiet, efficient operation

  • TypeATX
  • Faster wake-from-sleep with Modern Standby support
  • Lower power draw and cooler running via 80 PLUS Gold efficiency
  • Near-silent operation at low loads with Zero RPM fan mode
  • Clean, stable power delivery from resonant LLC topology with DC-to-DC conversion
  • Reduced coil whine for quieter overall system noise

Efficient ATX Power for Modern Systems

This 80W ATX power supply delivers 48V output with 80 PLUS Gold certification, ensuring high efficiency and lower power consumption. It is suited for compact builds or replacement units where a 48V rail is required and energy-efficient sleep states are valued.

Gold-Rated Efficiency with Silent Low-Load Operation

The resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine. At low and medium loads the Zero RPM fan mode stops the cooling fan entirely, enabling near-silent operation and cooler temperatures during typical use.

Modern Standby Support for Fast Wake Times

Modern Standby compatibility allows extremely fast wake-from-sleep performance and improved low-load efficiency. The ATX form factor fits standard mounting points, while the 80W capacity targets systems with modest power requirements rather than high-end multi-GPU configurations.

Questions sur cet article

How do I install this 48V 80W ATX power supply and what is the common mistake?

Mount the unit in the case using standard ATX screw holes, connect the 24-pin motherboard cable and any required 48V output leads, then secure all cables; the step often missed is verifying the 48V rail polarity before powering on.

What maintenance or replacement will this power supply need over time?

The 80 PLUS Gold certified unit uses a Zero RPM fan that stays off at low loads; dust the intake vents annually and expect the fan bearings to be the first wear item after several years of continuous operation.

Which limit appears first when this 48V 80W supply runs under sustained load?

The 80-watt total output ceiling is reached before thermal limits; once combined draw hits 80 W the protection circuit shuts the unit down to prevent overload.
