SKU CH-JFFC-GC5AB MPN DPS-400AB-17

400 W 1U server power supply for small desktop and AIO systems with SATA, IDE and 6-pin connectors

  • 400 W output powers 1U desktop and AIO systems
  • Compact 15 × 8.2 × 4 cm footprint fits tight chassis
  • 20+4 pin ATX connector feeds motherboard directly
  • 4+4 pin CPU and 6 pin GPU plugs support processor and graphics
  • Dual SATA and dual IDE leads drive multiple storage devices

Compact 1U server power supply

The WMtec DPS-400AB-17 delivers 400W of power in a 15 by 8.2 by 4 centimetre chassis designed for small 1U desktop and AIO NAS systems. It targets builders who need a direct replacement for the original Delta unit in space-constrained enclosures.

Sustained-load behaviour

The supply provides continuous 400W output through a single 20+4pin motherboard connector, one 4+4pin CPU connector, two SATA and two IDE drive connectors plus a 6pin graphics connector. Its fixed cable set matches the factory layout so voltage regulation stays stable under typical server workloads.

Installation notes

The 1U form factor slides into the original mounting brackets without modification. Installers must verify that the 20+4pin, 4+4pin, SATA, IDE and 6pin plugs match the target board because no adapter cables are included. Builders needing additional SATA ports or a second 6pin connector cannot use this unit.

Questions about this item

How loud does the DPS-400AB-17 run when it operates continuously at 400W?

The 1U form factor typically uses a high-speed fan that produces noticeable noise under full load, so expect audible airflow in a quiet room.

Which existing cables or connectors must my system already provide for this 400W unit to function?

Your motherboard needs a 20+4 pin ATX socket, a 4+4 pin CPU power header, plus SATA or IDE drive connectors and a 6-pin PCIe socket for graphics.

Will the DPS-400AB-17 fit and power an older 1U chassis that uses the same 15 by 8.2 cm footprint?

Yes, the 15 by 8.2 cm dimensions match the standard 1U server footprint, so it installs directly into compatible legacy enclosures.
