3000W ATX Power Supply

The KHACHIMO B201 S301 S601 ZXD3000 series delivers 3000 watts of continuous power in a standard ATX form factor. It is built for high-end workstations, multi-GPU render nodes and servers that demand sustained heavy loads. The unit carries 80 PLUS Gold certification and uses a resonant LLC topology with DC-to-DC conversion for clean, stable output.

Modern Standby and Silent Operation

This supply suits builders who need Modern Standby compatibility for near-instant wake from sleep and very low idle power draw. The Zero RPM fan mode keeps the system silent at low and medium loads by stopping the fan completely. Buyers who only need a modest power budget for office or home PCs should consider lower-wattage units instead.

80 PLUS Gold Efficiency

The single specification that decides fit is the 80 PLUS Gold rating, which confirms high efficiency across typical load ranges and directly reduces waste heat and operating cost. If your build requires a different efficiency tier or a lower maximum output, this model will not match those requirements.

Questions about this item

How quiet is the KHACHIMO B201 S301 S601 3000W PSU during all-day use?

The Zero RPM fan mode stops the fan completely at low and medium loads, while 80 PLUS Gold efficiency and resonant LLC topology with DC-to-DC conversion reduce heat and coil whine for near-silent operation.

What cables or connectors must I already have to install this KHACHIMO 3000W ATX power supply?

As an ATX unit it uses standard motherboard, CPU and PCIe connectors; ensure your case and components accept regular ATX cabling before fitting.

Will this KHACHIMO ZXD3000 PSU work reliably with older hardware I plan to keep?

The DC-to-DC conversion and resonant LLC topology deliver clean, consistent power compatible with legacy components, and Modern Standby support enables efficient sleep states on newer platforms.
