KHACHIMO 550W Server Power Supply R320 R420

SKU CH-AXEF-M9R4Q

A 550W ATX server power supply tested working for R320 and R420 systems

  • TypeATX
  • 550W output powers Dell R320 and R420 servers
  • ATX form factor fits standard server chassis
  • Tested working so it arrives ready to install
  • Good quality construction supports continuous server operation

Compatible server power supply

This 550W unit replaces the DH550E-S0, DPS-550NB A and AC550E-S0 models used in R320 and R420 servers. It delivers standard ATX power for rack-mount systems requiring a direct-fit replacement. Each unit is tested working before dispatch.

Sustained 550W output

The supply maintains its rated 550W continuously under server workloads rather than peaking briefly. Stable rails protect components during extended uptime. It suits environments where the power draw stays near the maximum for long periods.

商品問答

How much heat or fan noise does the 550W server power supply generate when running continuously?

The 550W unit is tested working and built for server chassis such as the R320 and R420, where airflow is managed by the system fans rather than the supply alone.

Which Dell PowerEdge servers accept the DH550E-S0 or DPS-550NB A model directly?

The supply matches part numbers 4XX1H and J6J6M used in PowerEdge R320 and R420 systems, so those servers already have the correct backplane and cabling.
