  • TypeATX
  • Fast wake-from-sleep with Modern Standby support
  • 80 PLUS Gold efficiency lowers consumption and heat
  • Fan stays off at low loads for silent running
  • Resonant LLC plus DC-to-DC gives clean stable power
  • 14-pin 280W ATX unit fits compatible systems

14-pin 280 W ATX power supply

The KHACHIMO HK380-16FP delivers 280 watts through a 14-pin ATX connector. It suits compact desktops and workstations that require this specific pin layout and power level.

Build integration and headroom

The unit fits standard ATX mounting points and uses a resonant LLC topology with DC-to-DC conversion for stable voltages. Zero RPM fan mode stops the fan at low and medium loads, reducing noise. Modern Standby support enables faster wake-from-sleep and efficient low-power states.

Upgrade context

This supply replaces an older 280 W unit that lacks 80 PLUS Gold efficiency, Modern Standby compatibility or a zero-fan mode. The jump is worthwhile when the existing PSU cannot meet the motherboard's 14-pin requirement or when quieter, cooler operation at idle is a priority.

Highlights

  • 80 PLUS Gold efficiency lowers consumption and heat
  • Fan stays off at low loads for silent running
  • Resonant LLC plus DC-to-DC gives clean stable power

Questions about this item

What happens when the 280 W limit is reached during sustained use?

The 280 W rating is the maximum continuous output; exceeding it triggers over-power protection that shuts the unit down.

How does the 14-pin connector and Zero RPM fan mode affect noise and heat during all-day operation?

The 14-pin design delivers power efficiently while the fan stays off at low and medium loads, keeping noise near zero and temperatures lower.

Which motherboard must already be present for the 14-pin 280 W unit to work?

A motherboard with a matching 14-pin ATX power connector is required; standard 24-pin boards will not connect.
