KHACHIMO 28V 250W ATX Power Supply

SKU CH-6D0F-8E338

An ATX power supply delivering 28 V at 250 W with 80 PLUS Gold efficiency, Modern Standby support, Zero RPM fan mode and resonant LLC topology with DC-to-DC conversion

  • TypeATX
  • Modern Standby support for faster wake-from-sleep
  • 80 PLUS Gold efficiency for lower power draw and cooler running
  • Zero RPM fan mode for silent operation at low loads
  • Resonant LLC with DC-to-DC conversion for clean power and reduced coil whine
  • ATX form factor delivers 250 W at 28 V

Modern Standby ATX Supply

This 28 V ATX power supply delivers 250 W of continuous output and is built for systems that require Modern Standby compatibility. It carries 80 PLUS Gold certification, so it runs efficiently at typical loads while keeping heat and fan noise low. The resonant LLC topology with DC-to-DC conversion provides clean, stable voltage rails and helps reduce coil whine. It is a new unit suited to compact or low-power builds that rely on fast wake-from-sleep behaviour.

Silent Low-Load Operation

The Zero RPM fan mode stops the fan completely at low and medium loads, giving near-silent running during office work or media playback. Builders who need a quiet, efficient ATX supply for a Modern Standby system will match these features. Buyers who require higher wattage for discrete graphics cards or multi-drive arrays should look at larger-capacity units instead.

28 Volt Output Rail

The defining specification is the 28 V output, which determines whether this supply matches the motherboard or chassis power input requirement. Verify that your platform expects a 28 V ATX source before purchasing, as standard ATX designs typically use different main voltage rails.

Questions sur cet article

How long can the 250 W output be sustained before protection triggers?

The unit is rated for continuous 250 W delivery; over-current and over-temperature protection engage only if that limit is exceeded.

How quiet is the 80 PLUS Gold supply under all-day load?

Zero RPM mode keeps the fan off at low and medium loads, while the LLC resonant topology and DC-to-DC conversion minimise coil whine for near-silent operation.

Which motherboard connector does the 28 V ATX unit require?

A standard ATX 24-pin motherboard connector is needed for the supply to power the system.
