KHACHIMO

KHACHIMO 15W ATX Power Supply 80 PLUS Gold

SKU CH-QBVJ-87SET

A 15W ATX power supply with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby support

  • TypeATX
  • Modern Standby support for near-instant wake from sleep
  • 80 PLUS Gold efficiency cuts power draw and heat
  • Zero RPM fan mode keeps the unit silent at low load
  • Resonant LLC topology with DC-to-DC conversion delivers clean, stable power
  • 15 W ATX form factor fits compact, low-power builds

Compact ATX Power Supply

The KHACHIMO 15W ATX unit is a new power supply built for systems that demand efficient, low-wattage delivery. It suits compact workstations, embedded appliances, or secondary rigs where a full-size PSU would be oversized. Its 80 PLUS Gold certification confirms high efficiency across typical loads.

Build Integration

The ATX form factor lets it mount in standard chassis cut-outs while the 15W output keeps cable routing minimal and heat output low. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and supports deeper sleep states.

Sustained Operation

Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent running. The same resonant LLC design reduces coil whine and maintains stable voltage during extended sessions. Gold-rated efficiency lowers sustained power draw, helping the unit run cooler when the system remains active for long periods.

Questions about this item

Will the 15 W capacity limit sustained heavy loads?

The unit is rated for 15 W continuous output, so sustained loads above that level will exceed its design capacity and may trigger protection shutdown.

How does the Zero RPM fan mode affect heat and noise during all-day operation?

At low and medium loads the fan stops completely, eliminating noise; the 80 PLUS Gold efficiency and resonant LLC topology keep waste heat low so temperatures stay manageable even when running continuously.

What motherboard power connectors must my system already have for this ATX supply to work?

A standard 24-pin ATX motherboard connector and the corresponding CPU power connector (4-pin or 8-pin) are required; the supply uses the regular ATX pinout so any compatible motherboard will connect directly.
