KHACHIMO 18-75V 5V 15A ATX Power Supply

SKU CH-VXYB-N1D0Q

ATX power supply delivering 15 A at 5 V from an 18-75 V input with 80 PLUS Gold efficiency, zero-RPM fan mode and resonant LLC topology

  • TypeATX
  • Modern Standby support for near-instant wake from sleep
  • 80 PLUS Gold efficiency cuts power draw and heat
  • Zero RPM fan mode stops the fan at low loads
  • Resonant LLC with DC-to-DC delivers clean power and less coil whine
  • Wide 18-75 V input range suits industrial and embedded systems

Wide-Input ATX Power Supply

This KHACHIMO unit accepts a 18-75V DC input and delivers a regulated 5V rail rated at 15A, making it suitable for industrial PCs, embedded systems, or mobile platforms where standard mains power is unavailable. It uses an ATX form factor and carries an 80 PLUS Gold efficiency rating for reduced waste heat and lower operating costs.

Standard ATX Mounting with Zero-RPM Mode

The supply fits a conventional ATX cut-out and uses the usual mounting screws, so installation follows normal chassis layouts. Its Zero RPM fan mode stops the fan completely at low and medium loads, eliminating noise until higher thermal demand requires active cooling.

18-75V DC Input Range

The defining specification is the wide 18-75V DC input window; the unit will not operate from AC mains or from voltages outside this range. Builders needing a standard ATX supply for wall power should choose a conventional AC-input model instead.

Questions about this item

How can I confirm the power supply is delivering stable 5 V output after installation?

Measure the 5 V rail with a multimeter under load; it should read close to 5 V and the unit’s 80 PLUS Gold rating indicates high efficiency across typical loads.

What comes in the box and do I need to buy any cables separately?

The box contains the ATX power supply unit only; any additional power cables or adapters required for your build must be purchased separately.

Which capacity should I choose for a system that draws up to 75 W on the 5 V rail?

This model provides 15 A at 5 V (75 W), matching the 18–75 V input range; select it if your 5 V load stays within 75 W.
