KHACHIMO 75W ATX Power Supply HF75W-DEK-B

SKU CH-KAEB-81TN6

A 75 W ATX power supply with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby support for fast wake times

  • TypeATX
  • Modern Standby support enables extremely fast wake-from-sleep times
  • 80 PLUS Gold certification delivers high efficiency for 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 provides clean, consistent power and reduces coil whine
  • 75 W output with 24 V 1.8 A and 5 V 3 A rails powers compatible systems

Ideal for low-power ATX builds

This 75 W ATX power supply targets compact or secondary systems that run Modern Standby and need efficient, quiet operation. It suits builders assembling small-form-factor PCs, home-theatre units or office workstations where low noise and fast wake-from-sleep matter more than high output. The 80 PLUS Gold rating keeps energy use and heat low under typical loads.

Verify motherboard and load requirements

Confirm your board uses a standard ATX connector and that total system draw stays well within the 75 W limit, including any 24 V 1.8 A and 5 V 3 A rail demands. The resonant LLC topology with DC-to-DC conversion delivers clean power, but the unit cannot support discrete graphics cards, multiple drives or high-wattage CPUs. Ensure the case can accommodate an ATX-form-factor PSU and that airflow reaches the fan even when Zero RPM mode is inactive.

Zero RPM fan mode changes daily acoustics

At low and medium loads the fan stops completely, removing mechanical noise during common tasks such as web browsing or media playback. Combined with the resonant LLC design, this reduces coil whine and enables deeper, more efficient sleep states supported by Modern Standby. The result is a near-silent experience for always-on or frequently-woken systems without extra configuration.

Questions about this item

What cables or connectors are included with the HF75W-DEK-B and what must be purchased separately?

The supplier data lists only the 75 W ATX unit itself; no cables, mounting screws or adapters are mentioned, so assume nothing extra is supplied.

Which version or capacity of the KHACHIMO HF75W-DEK-B should I choose for my build?

Only the single 75 W model with 24 V 1.8 A and 5 V 3 A outputs is offered; there are no alternative wattages or rail configurations to select.

What does the 80 PLUS Gold rating mean for everyday power draw and heat in my PC?

It certifies at least 80 % efficiency at typical loads, so the unit wastes less electricity, runs cooler and helps the fan stay off longer under light use.
