KHACHIMO RQ940 1600W ATX Power Supply

SKU CH-VZH8-5MSGH

ATX 1600W unit with 80 PLUS Gold efficiency, zero-RPM fan mode and LLC resonant topology for clean power and quiet operation

  • TypeATX
  • Modern Standby support enables ultra-fast wake times
  • 80 PLUS Gold certification delivers high efficiency and lower heat
  • Zero RPM fan mode stops the fan at low loads for silent running
  • Resonant LLC with DC-to-DC topology provides clean power and reduces coil whine
  • 1600W output handles demanding multi-GPU and workstation builds

High-Wattage ATX Power Supply

The KHACHIMO RQ940 delivers 1600W of ATX power for workstations and servers that draw sustained heavy loads. Its 80 PLUS Gold certification means lower power draw and less waste heat during continuous operation. Modern Standby compatibility allows extremely fast wake-from-sleep transitions. The resonant LLC topology with DC-to-DC conversion provides clean, consistent output and reduces coil whine.

Built-In Cooling and Efficiency Features

A Zero RPM fan mode stops the fan completely at low and medium loads for near-silent running. The resonant LLC topology with DC-to-DC conversion further cuts audible noise by suppressing coil whine. Together these features keep acoustic output minimal while maintaining high efficiency across the load range. The 80 PLUS Gold rating confirms efficient operation under typical workloads.

Compatibility Checks Before Purchase

Verify that your case can accommodate a 1600W ATX unit and that your motherboard supports Modern Standby sleep states. Confirm the mainboard and GPU power connectors on the unit match your components. Ensure your AC circuit can supply the required input current for full-load operation. Buyers needing redundant or hot-swap power modules should look at server-specific chassis designs.

Questions sur cet article

Will the 12 V rail on the RQ940 need a fan replacement after continuous 1600 W loads?

The Zero RPM mode keeps the fan off at low and medium loads; under sustained full power the fan runs normally and is the only moving part that may eventually need service.

What limit appears first when the RQ940 runs at 1600 W for hours?

Thermal protection engages once internal temperatures exceed the design threshold, capping output before any component is damaged.

How loud and hot does the RQ940 get during an all-day 1600 W workload?

80 PLUS Gold efficiency and LLC resonant topology reduce waste heat, while the fan spins only as fast as needed, keeping noise and temperatures lower than less efficient units.
