Z230WS 400W ATX Power Supply

The KHACHIMO Z230WS is a 400W ATX power supply built for modern desktop systems. It carries 80 PLUS Gold certification and supports Modern Standby for rapid wake-from-sleep. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power to components.

400W capacity and efficiency headroom

At 400W this unit comfortably handles mainstream processors and mid-range graphics cards under full load. Gold-rated efficiency keeps power draw, heat and fan noise lower across typical workloads. Demanding multi-GPU builds or extreme overclocking will exceed its available headroom.

Zero RPM fan mode and quiet operation

A Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent running. The resonant LLC design further reduces coil whine during quiet states. Systems that sustain heavy continuous loads will hear the fan spin up as temperatures rise.

Questions about this item

Will this 400W ATX unit power a system that still uses an older motherboard with a 20+4-pin connector?

Yes, the supply follows the ATX form factor so its 24-pin connector fits legacy 20-pin sockets when the extra four pins are left unplugged.

How can I confirm the Zero RPM fan mode is active after installation?

Under light loads the fan should remain completely still; you can verify by watching the fan blades through the grille while the system idles.

Which cables come attached to the DPS-400AB-19A and what must I source separately?

The power supply has fixed cables including the ATX 24-pin, CPU 4+4-pin, PCIe 6+2-pin and peripheral leads; any specialised adapters such as extra PCIe or Molex extensions must be purchased separately.
