godream DPS-400AB-17B power supply 400W 500W

SKU CH-ZBJD-5RQ9B

A 400W ATX power supply with a 500W peak rating for Delta ITX NAS systems

  • TypeATX
  • ATX form factor fits standard chassis
  • 400 W continuous output powers typical builds
  • 500 W peak capacity handles short load spikes
  • 12 V rail included for legacy hardware
  • Switching topology delivers efficient power conversion

Purpose-built Delta ITX NAS replacement

This 400 W rated ATX supply with a 500 W peak rating is designed for Delta ITX NAS chassis that require the M41 or K39 form factor and a -12 V rail. It serves builders who need a direct-fit unit for those specific small-footprint servers.

Capacity and headroom

The unit delivers a continuous 400 W and can reach 500 W for short bursts, which is sufficient for typical ITX NAS workloads such as file serving and light virtualization. Sustained loads above 400 W will exceed the rated output and may trigger protection or instability.

Build and connectors

The 1U switching design fits the compact Delta enclosure and uses the proprietary M41/K39 connector layout, so cable routing matches the original chassis without adapters. Builders using standard ATX cases or requiring modular cables will find the fixed harness and non-standard pinout incompatible.

Preguntas sobre este artículo

Will the Delta DPS-400AB-17B fit in the 1U chassis I already own?

The unit is a 1U form-factor ATX supply rated at 400 W continuous and 500 W peak, matching the M41 and K39 NAS chassis specifications.

How can I confirm the -12 V rail is operating correctly after installation?

Measure the -12 V output with a multimeter under load; it should read within ATX tolerance of the rated -12 V line.

Does the package include a power cord and mounting hardware for the 1U case?

Only the switching power supply module is supplied; cables and fixing screws are not included.
