SKU CH-42F4-WDJS8

An ATX power supply delivering 1600 W with 80 PLUS Gold efficiency, Modern Standby support, Zero RPM fan mode and resonant LLC topology with DC-to-DC conversion

  • TypeATX
  • Fast wake-from-sleep with Modern Standby support
  • Lower power draw thanks to 80 PLUS Gold efficiency
  • Silent operation at low loads with Zero RPM fan mode
  • Clean, stable power from resonant LLC topology with DC-to-DC conversion
  • 1600W ATX output for demanding system builds

High-capacity ATX power unit

The KHACHIMO DS1600SPE-3-407 delivers 1600W of continuous power for demanding desktop builds. It suits workstations and enthusiast rigs that draw heavy loads from multiple GPUs or high-end CPUs. Builders who need less than 1600W should consider a lower-capacity unit.

Sustained-load behaviour

An 80 PLUS Gold rating means the unit maintains high efficiency across typical and peak loads, reducing waste heat and keeping internal temperatures lower. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power during extended sessions. Zero RPM fan mode stays active at low and medium loads for near-silent operation.

ATX interface limits

The ATX form factor fits standard chassis and motherboard mounting points without modification. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency for supported platforms. Systems without Modern Standby support will not benefit from the faster sleep transitions.

Questions about this item

How loud and hot does the 1600W unit get when running all day?

The 80 PLUS Gold rating keeps efficiency high, so waste heat and fan noise stay low; the Zero RPM mode stops the fan entirely at low and medium loads for near-silent operation.

Which cables or connectors must I already have for this PSU to work?

It uses the standard ATX form factor, so your case must accept an ATX power supply and your motherboard needs the usual 24-pin ATX and CPU power connectors.

Will the DS1600SPE-3-407 play nicely with older components I want to keep?

Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine, making it compatible with legacy hardware that is sensitive to voltage ripple.
