  • ATX form factor fits standard server chassis
  • 400W output powers typical server workloads
  • Tested working before shipment ensures reliability
  • Quality components support stable operation
  • Listed April 2024 indicates current production

Server-grade ATX unit

The KHACHIMO P2H-6400P is a 400W ATX power supply built for server environments. It suits administrators and integrators assembling rack or tower systems that need reliable DC output. The unit is new and tested working before it leaves the factory.

Normal-load thermals and acoustics

Under typical server workloads the supply runs within its rated 400W envelope without excessive fan noise. Good-quality components keep heat output modest during everyday operation, helping maintain stable voltages across the rails. Power draw scales with the attached hardware rather than the unit’s maximum rating.

Sustained-load behaviour

During prolonged heavy demand the power supply continues to deliver its full 400W capacity without shutdown or voltage droop. The design handles continuous operation in 2024 server builds where uptime matters more than burst peaks. Buyers who need more than 400W for multi-GPU or high-density configurations should select a higher-capacity model.

Questions about this item

How do I install the ATX power supply and which step is most often missed?

Mount the unit in the chassis with the four screws, connect the 24-pin main and 8-pin CPU cables, then switch the rear I/O toggle to on before pressing the front power button.

What maintenance will the 400W server supply need later?

Vacuum dust from the intake grill every 6 to 12 months and listen for fan bearing noise; replace the unit if voltages drift under sustained load.

What limit appears first during continuous 400W operation?

The internal thermal protection trips when the heatsink temperature exceeds the design threshold, causing an automatic shutdown until the unit cools.
