KHACHIMO

KHACHIMO 260W ATX Power Supply Gold 80 PLUS

SKU CH-6EFR-3K6MG

ATX power supply delivers 260 W with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby compatibility

  • TypeATX
  • Modern Standby compatible for extremely fast wake-from-sleep times
  • 80 PLUS Gold certified for high efficiency and lower power consumption
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine
  • ATX form factor fits standard desktop builds with 260W output

Compact 260W ATX unit

This 260W ATX power supply is built for small-form-factor desktops and office refreshes where a standard chassis cannot accept larger units. It delivers reliable power for integrated graphics configurations and basic productivity workloads without the bulk of higher-wattage alternatives. The new condition ensures full component life from day one. Systems needing discrete graphics cards or heavy multi-drive arrays should look elsewhere.

Thermals and efficiency

The 80 PLUS Gold certification means high efficiency across typical loads, reducing waste heat and keeping internal temperatures lower. A Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation in quiet offices. Resonant LLC topology with DC-to-DC conversion supplies clean, consistent power while minimising coil whine. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency.

Upgrade path and fit

This unit replaces proprietary 260W modules such as D19-260P1A, D19-260P1B, M76034, L70041-002, L70041-004 and PA-2261-5HK-HPF found in select compact workstations. The jump is worth it when the original supply has failed or when Gold-rated efficiency and fan-stop behaviour are desired for a quieter, cooler-running system. Builders needing more than 260W of continuous power cannot use this model.

Questions about this item

How do I install this ATX power supply and which step is often missed?

Mount the unit in the case using four screws, connect the 24-pin motherboard cable and the 4-pin CPU power cable, then flip the rear I/O switch to on; the step most people forget is plugging in the 4-pin CPU connector before the first boot.

What maintenance will this 260W Gold unit need over time?

Clean dust from the intake grill every few months with compressed air; the Zero RPM fan mode means the fan runs less often, but bearings will eventually wear and the whole unit should be replaced if voltages drift out of spec.

What limit appears first when this PSU runs at high load for long periods?

The 260W total output ceiling is reached before thermal limits, so sustained draws near that level will trigger over-power protection and shut the system down.
