ATX power supply delivering 3000 W with 80 PLUS Gold efficiency, zero-RPM fan mode and LLC resonant topology for silent, clean power

  • Product typeATX
  • Near-instant wake from sleep with Modern Standby support
  • Lower electricity draw and heat via 80 PLUS Gold efficiency
  • Silent running at typical loads thanks to Zero RPM fan mode
  • Clean, stable power delivery through resonant LLC with DC-to-DC topology
  • 3000 W capacity in an ATX form factor for high-end builds

3000W ATX Power Supply

The KHACHIMO ZXD2400 V4.0 is a 3000 watt ATX power supply built for high-demand desktop systems. It carries 80 PLUS Gold certification for efficient power delivery and reduced heat output. Resonant LLC topology with DC-to-DC conversion provides stable voltage regulation and lower coil whine. Modern Standby support enables faster wake-from-sleep transitions and improved low-load efficiency.

Suited For Extreme Builds

This unit targets enthusiasts assembling multi-GPU workstations, heavy rendering rigs or servers that draw sustained high current. Zero RPM fan mode keeps acoustics near silent during light workloads. Builders needing only modest wattage for mainstream gaming or office PCs will find the capacity excessive and should consider lower-output models that match their actual load.

Capacity And Headroom

The 3000 watt rating delivers ample headroom for multiple high-end graphics cards, dense storage arrays and overclocked processors running simultaneously. Efficiency peaks at typical loads thanks to the Gold-rated design, keeping thermals manageable. Systems with single mid-range GPUs or basic productivity workloads will operate far below the supply's optimal efficiency curve, wasting potential.

Questions about this item

What motherboard power connector does the ZXD2400 V4.0 require to operate?

It uses a standard ATX connector, so any motherboard with a 24-pin ATX socket and matching CPU power headers will work.

Will the 3000W unit stay compatible with an older ATX motherboard I plan to keep?

Yes, the ATX form factor and standard pin-out mean it fits legacy boards, and the DC-to-DC design delivers stable voltages even at very light loads.

How can I confirm the Zero RPM Fan Mode is active after installation?

Under light load the fan should stop spinning completely; you can also monitor fan speed in the BIOS or hardware-monitoring software to verify it reads 0 RPM.
