Compact server power supply

The Ruth's sister DPS400AB-12 is a 400 watt 1U unit built for small-form-factor desktops and servers. Its non-modular design keeps cabling simple for integrators who prefer a fixed harness.

Gold efficiency and fixed connectors

Active PFC and 80 PLUS Gold certification reduce waste heat in tight chassis. The loom provides a 24 pin motherboard plug, one 4 pin CPU connector, two SATA, two IDE, one floppy and a single 6 pin peripheral lead.

Ready for legacy and modern drives

Mixed SATA and IDE headers let builders connect current solid-state drives alongside older mechanical units without adapters. The 6 pin connector supports add-in cards that draw auxiliary power. Builders needing modular cables or higher 12 volt current should look elsewhere.

Questions about this item

What does the 80 PLUS Gold rating mean for the DPS400AB-12 in practice?

The 80 PLUS Gold certification confirms the supply meets Gold-level efficiency targets under the standard test regime.

What physical space and connector clearance does the 15 cm by 4 cm by 8 cm 1U chassis need?

It fits a standard 1U rack or ITX case bay and provides one 24-pin, one 4-pin, two SATA, two IDE, one floppy and one 6-pin connector.

How is the non-modular DPS400AB-12 wired in, and which step is often missed?

Mount the 1U unit, route all fixed cables, then attach the 24-pin motherboard, 4-pin CPU, two SATA, two IDE, floppy and 6-pin plugs; the step most often missed is seating the 4-pin CPU power connector.
