1U 400W ATX power supply for rack servers

This KHACHIMO DPS-400AB-20A is a 400W ATX switching power supply built in a 1U form factor. It suits rack-mount servers and compact workstations that require a standard ATX pin-out in a single rack-unit chassis. The unit is supplied new and has been tested working.

Check 1U clearance and ATX connector fit

Verify that your chassis accepts a 1U-height power supply and that the motherboard uses a standard ATX power connector. Confirm the rear mounting holes align with your rack rails and that the total system draw stays within the 400W rating. The model suffixes 12, 17 and 20 may indicate revision differences, so match the exact part number to your hardware documentation.

Questions about this item

Does the DPS-400AB-20A come with mounting screws and power cables, or must I buy them separately?

The unit is supplied as a bare 1U switching power supply; mounting screws and AC/DC cables are not included and must be sourced separately.

Which variant — DPS-400AB-12B, DPS-400AB-17B or DPS-400AB-20A — matches my server's power connector and airflow?

The suffixes 12, 17 and 20 denote different connector pin-outs and fan orientations; verify your chassis service manual to select the matching variant.
