SKU CH-MTPW-KGKP4

550 W ATX server power supply tested working for reliable operation

  • Product typeATX
  • 550 W output powers demanding server builds
  • ATX form factor fits standard chassis layouts
  • Tested working so it arrives ready to install
  • Good quality components support reliable long-term operation

Server-ready 550 W ATX power

This KHACHIMO unit delivers 550 watts from a standard ATX form factor and carries the D550E-S1 model designation. It is built for rack-mount or tower servers that require reliable, continuous power delivery. Each unit is tested working before it leaves the supplier.

Fits 185 mm depth bays and standard ATX mounts

The 185 mm chassis depth aligns with many 1U and 2U server rails, while the ATX connector layout works with common server mainboards. It frees up internal space compared to bulkier redundant modules and suits builds that need a single, non-hot-swap supply. Buyers needing redundant or hot-swap capability should look elsewhere.

Questions about this item

What sustained load limit does the 550 W rating represent for this server supply?

The 550 W figure is the continuous output rating, meaning the unit is designed to deliver that power level steadily under normal server operating conditions.

How does the 185 V input marking affect heat and noise when the supply runs all day?

The 185 V designation indicates the low-end input voltage range; operating at higher typical voltages generally improves efficiency, which can reduce waste heat and fan noise during extended use.
