  • TypeATX
  • Fast wake-from-sleep with Modern Standby support
  • 80 PLUS Gold efficiency cuts power draw and heat
  • Zero RPM fan mode keeps system silent at low loads
  • Resonant LLC topology delivers clean power and reduces coil whine
  • DC-to-DC conversion enables deeper, more efficient sleep states

300W ATX Power Supply

The KHACHIMO AX100/AX150I is a 300W ATX power supply built for modern desktop systems. It carries 80 PLUS Gold certification for high efficiency and lower power consumption. Modern Standby compatibility enables extremely fast wake-from-sleep times. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine.

Compatibility Check

Verify that your chassis accepts a standard ATX form factor unit before ordering. Confirm the motherboard requires a 24-pin main connector and the necessary CPU or GPU auxiliary connectors. Ensure the 300W rated output matches the total power draw of your installed components. Check that the physical dimensions suit your case interior.

Upgrade From Lower Efficiency Units

This unit replaces older power supplies lacking 80 PLUS Gold efficiency or Modern Standby support. The jump is worthwhile when you need near-silent operation from the Zero RPM fan mode at low and medium loads. It also suits builds that demand cleaner power delivery and reduced coil whine for quieter daily use.

  • 80 PLUS Gold efficiency cuts power draw and heat
  • Zero RPM fan mode keeps system silent at low loads

Questions about this item

What comes in the box with the KHACHIMO AX100/AX150I 300W ATX power supply and what must be purchased separately?

The unit ships with the power supply itself. Standard ATX power cables for motherboard, CPU, drives and graphics cards are attached or included. A mains power cord is typically required separately if not already owned.

Which model variant should I choose between the AX100 and AX150I versions?

The AX100 and AX150I share the same 300W ATX platform, 80 PLUS Gold efficiency, Zero RPM fan mode and LLC resonant topology. Choose based on the exact part number your system or chassis specifies.

What does the 300W rating mean for actual system building?

The 300W rating is the maximum continuous DC output the supply can deliver across all rails combined. It supports modern standby sleep states and maintains Gold-level efficiency at typical loads, reducing heat and fan noise.
