KHACHIMO 280W 80 PLUS Gold ATX power supply

SKU CH-5PXN-0960C

ATX power supply delivering 280 W with 80 PLUS Gold efficiency, zero-RPM fan mode and LLC resonant topology for quiet, low-loss operation

  • TypeATX
  • Modern Standby support delivers near-instant wake from sleep
  • 80 PLUS Gold certification cuts power draw and keeps thermals lower
  • Zero RPM fan mode stops the fan at light loads for silent running
  • Resonant LLC with DC-to-DC conversion supplies clean power and reduces coil whine
  • 280 W ATX capacity powers compact builds efficiently

Ready for Modern Standby builds

This 280W ATX unit carries 80 PLUS Gold certification and is designed for systems that use Modern Standby sleep states. It suits compact workstations or small-form-factor PCs where efficient low-load operation matters. Buyers who need higher continuous output for multi-GPU configurations should look elsewhere.

Gold efficiency with Zero RPM mode

At low and medium loads the fan stops completely, delivering near-silent running while the Gold-rated topology keeps waste heat and power draw low. Resonant LLC with DC-to-DC conversion maintains clean voltage regulation and reduces coil whine during quiet operation.

Dual 8-pin connectors for focused delivery

Two 8-pin outputs feed the CPU and GPU directly, simplifying cable routing in tight chassis. The ATX form factor fits standard mounting points, while the Modern Standby support enables extremely fast wake-from-sleep times for responsive daily use.

Questions about this item

How do I connect this 280 W ATX supply to a motherboard that needs two 8-pin CPU power connectors?

Plug both of the unit's native 8-pin EPS cables directly into the motherboard sockets; no adapters are required.

What part of this unit will most likely need attention after several years of daily use?

The cooling fan is the only moving component; its bearings can wear and may eventually require cleaning or replacement.

Which protection limit activates first when the supply runs at full 280 W output for an extended period?

Over-temperature protection will trip before any other safeguard if sustained load pushes internal heat past the design threshold.
