KHACHIMO

KHACHIMO 15W ATX 80 PLUS Gold power supply

SKU CH-5RRX-XR5TW

A 15 W ATX unit with 80 PLUS Gold efficiency, Modern Standby support, zero-RPM fan mode and resonant LLC topology for clean, quiet power

  • TypeATX
  • Fast wake-from-sleep with Modern Standby support
  • High efficiency cuts power use and heat with 80 PLUS Gold
  • Near-silent operation via Zero RPM fan mode at low loads
  • Clean, stable power from resonant LLC topology with DC-to-DC
  • Reduced coil whine for quieter performance under load

ATX power supply for low-power builds

The KHACHIMO 15W ATX unit targets compact systems and embedded boards that draw very little power. It suits builders assembling thin clients, digital signage players or specialised appliances where a high-wattage supply would be oversized and inefficient. Modern Standby compatibility ensures rapid wake-from-sleep for always-ready operation.

80 PLUS Gold efficiency with Zero RPM fan

Rated 80 PLUS Gold, the supply delivers high efficiency across its load range, reducing consumption and heat output. A Zero RPM mode stops the fan completely at low and medium loads, providing near-silent running in typical idle or light-use scenarios. Resonant LLC topology with DC-to-DC conversion further lowers acoustic noise by minimising coil whine.

ATX form factor with resonant LLC topology

The standard ATX footprint allows direct mounting in compatible chassis without adapters. Resonant LLC and DC-to-DC circuitry supply clean, stable rails for sensitive components while supporting deeper sleep states. This combination suits space-constrained enclosures where thermal headroom and quiet operation are priorities.

Questions about this item

How do I install this 15 W ATX power supply and what step is often missed?

Mount the unit in the case with the four standard screws, connect the 24-pin ATX and any required peripheral cables, then verify the motherboard BIOS has Modern Standby enabled so the fast wake and low-load efficiency features actually activate.

What maintenance or replacement will this 80 PLUS Gold unit need over time?

The Zero RPM fan mode keeps the fan off at low and medium loads, reducing bearing wear; plan to clean dust from the intake grill once a year and replace the unit only if fan noise appears or voltages drift out of spec.

What limit appears first when this 15 W supply runs under sustained load?

The 15 W total power ceiling is reached before thermal or efficiency limits; continuous draw near that level will keep the fan spinning and prevents the Zero RPM mode from engaging.
