KHACHIMO CRPS 400W ATX Power Supply

The KHACHIMO CRPS 400W ATX Power Supply delivers 400 watts of continuous power for desktop PCs. It carries 80 PLUS Gold certification for high efficiency and supports Modern Standby for fast wake-from-sleep transitions. The unit is built with Resonant LLC topology and DC-to-DC conversion to provide clean, consistent power output.

Compatibility check before ordering

Verify that your chassis accepts a standard ATX form-factor power supply and that the motherboard uses a 24-pin ATX main connector. Ensure the graphics card and CPU power connectors required by your build match the cables supplied with this unit. Confirm the total system power draw stays within the 400 W rating under full load.

Thermals noise and power draw

80 PLUS Gold certification means the unit runs cooler and wastes less energy across typical workloads. A Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion further reduces coil whine and supports efficient sleep states.

Questions about this item

What cables come with the KHACHIMO CRPS 400W ATX PSU and what must I buy separately?

The unit ships with a standard ATX power cable set; no extra cables are included, so any specialised GPU or drive cables must be sourced separately.

How do I decide between the available versions of the ATN-5400V 400W Gold unit?

Only one 400W Gold model is listed, so there is no capacity or version choice to make.

What does the 80 PLUS Gold rating mean for daily use in my PC?

It certifies at least 80 % efficiency at typical loads, reducing waste heat, cutting electricity draw and allowing the fan to stay off longer under light work.
