KHACHIMO CRPS 400W Industrial Power Supply

The KHACHIMO CRPS P2H-5400V is a 400W ATX power supply built for industrial monitoring systems. It delivers 80 PLUS Gold certified efficiency and supports Modern Standby for rapid wake-from-sleep performance. A resonant LLC topology with DC-to-DC conversion provides clean, consistent power to sensitive equipment. The unit is new and intended for continuous, reliable operation in demanding environments.

Suited for stable industrial workloads

This supply suits integrators who need dependable 400W output with high efficiency and low acoustic noise. The zero RPM fan mode keeps the system near-silent at low and medium loads, while the resonant topology reduces coil whine. It is not for builds requiring higher wattage headroom, redundant power configurations, or server-grade hot-swap CRPS form factors. Buyers needing modular cabling for compact cases should verify cable management separately.

Check ATX fit, connector needs

Before ordering, confirm your chassis accepts a standard ATX power supply and that the fixed cable set matches your motherboard, CPU and peripheral connectors. Ensure the motherboard and operating system fully support Modern Standby to use the fast wake and low-load efficiency features. Verify the 400W continuous rating meets the total system draw under peak load, including any industrial add-in cards or storage arrays.

Questions about this item

What motherboard connector does the P2H-5400V need to deliver power?

The unit follows the ATX form factor, so it connects to a standard 24-pin ATX motherboard socket and matching CPU/PCIe leads.

Will the 400W CRPS unit start reliably with a legacy motherboard that lacks Modern Standby support?

Yes, the power supply works with any ATX-compatible board; Modern Standby compatibility simply adds faster wake times on newer platforms.

How can I confirm the fan’s Zero RPM mode is active after assembly?

At low or medium load the fan stops completely; listen for silence and verify the fan blades are stationary while the system runs.
