ATX power supply unit with gold certification badge and 1400W label

KHACHIMO

KHACHIMO T7920 1400W power supply 80 PLUS Gold Zero RPM fan

SKU CH-WWR1-4BRS9

A 1400W ATX power supply with 80 PLUS Gold efficiency, Zero RPM fan mode for silent low-load operation, and Modern Standby compatibility

  • TypeATX
  • 80 PLUS Gold certification cuts power draw and heat
  • Zero RPM fan mode stops the fan at low and medium loads for silent running
  • Modern Standby support gives faster wake times and better low-load efficiency
  • Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine
  • 1400 W ATX output handles demanding multi-GPU and workstation builds

High-Wattage ATX Power Supply for Demanding Builds

The KHACHIMO T7920 delivers 1400W of continuous power through a standard ATX form factor. It targets workstations and high-end gaming systems that require substantial headroom for multiple GPUs or heavily overclocked components. The unit is new and carries 80 PLUS Gold certification for verified efficiency.

Efficient Cooling With Semi-Passive Operation

80 PLUS Gold certification ensures high efficiency across typical loads, reducing waste heat and overall power draw. A Zero RPM fan mode stops the cooling fan completely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion supplies clean power while minimising coil whine and supporting modern sleep states.

Modern Standby Support for Instant Wake

Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. This feature benefits users who frequently suspend their system rather than shutting down. Buyers whose motherboards lack Modern Standby support will not gain this advantage.

Questions about this item

How do I install the 1400W ATX power supply and which step do builders often miss?

Mount the unit in the case with the four screws, connect the 24-pin motherboard cable and all required GPU or CPU leads, then verify the Zero RPM fan switch is set correctly — many forget to toggle it before closing the case.

What maintenance or replacement will the 1400W unit need later?

The only serviceable part is the cooling fan; dust it annually and replace it if bearing noise appears, while the internal capacitors and LLC resonant topology components are rated for the full product life.

What limit shows up first under sustained load on the 1400W supply?

At continuous high draw the 80 PLUS Gold efficiency curve drops, so waste heat becomes the limiting factor before the 1400W rating is reached.
