400W ATX Power Supply

The KHACHIMO CRPS 400W ATX Power Supply MRW-6400P-R is a new 400 watt unit built for standard desktop builds. It carries 80 PLUS Gold certification for high efficiency and lower power draw. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine. Modern Standby compatibility enables extremely fast wake-from-sleep times.

Builders who value quiet operation

This unit suits builders who want near-silent performance at low and medium loads thanks to its Zero RPM fan mode. It also fits systems that rely on Modern Standby for quick resume and better low-load efficiency. Buyers needing more than 400 watts for high-end graphics cards or multi-GPU configurations should look at higher-capacity models.

Fits standard ATX cases and modern motherboards

The ATX form factor fits standard chassis layouts without proprietary mounting constraints. 80 PLUS Gold efficiency frees up thermal headroom and reduces overall system heat output. Zero RPM fan mode eliminates fan noise during idle and light workloads. Modern Standby support allows the platform to enter and exit low-power states quickly.

Questions about this item

What motherboard power connectors must my board provide for this CRPS 400W ATX unit?

Your motherboard needs a standard 24-pin ATX connector and a 4-pin or 8-pin CPU power connector to work with this supply.

Will the Zero RPM fan mode stay silent if I pair this PSU with an older GPU that idles at higher power draw?

The fan remains off at low and medium loads; if the older GPU pushes the load above the medium threshold the fan will start automatically.

How can I confirm the 80 PLUS Gold efficiency is active after installation?

Enable Modern Standby in the OS, put the system to sleep, and verify wake time is near-instant — Gold efficiency supports the low-power states that make this possible.
