Compatible NAS Replacements

This 240 W server power supply replaces the original unit in Synology DS1815+, DS1813+, DS2015xs, RS815+, DS1513+ and DS1515+ systems. It accepts 110-240 V input at 50/60 Hz and delivers a single 12 V rail through a 24+12+8 pin connector set. The compact 15.5×8.3×4.2 cm form factor fits the 1U chassis used by these models.

Thermals and Power Draw

Rated at 240 W maximum output, the unit operates within the 80 Plus efficiency series to reduce waste heat under normal NAS loads. The 12 V output matches the platform power architecture, so the supply runs cool and quiet during typical file-serving workloads. Universal 110-240 V input eliminates the need for voltage selection when moving the appliance between regions.

Build and Connectors

Weighing 800 g, the supply uses a metal enclosure suited to continuous server operation. The fixed 24-pin, 12-pin and 8-pin leads connect directly to the NAS backplane without adapters, ensuring secure mating in the dense 1U layout. Verify the part number DPS-250AB-44B against the label on the failed unit before installation to guarantee pin-out compatibility.

Questions about this item

How do I install the DPS-250AB-44B and connect its 24+12+8 pin main connector correctly?

Slide the 1U unit into the chassis bay until the latch clicks, then attach the 24-pin, 12-pin and 8-pin plugs to the matching motherboard headers; the keyed shapes prevent reversed insertion, which is the step most often missed.

What maintenance will the DPS-250AB-44B need after extended use?

Periodically blow dust from the intake vents and fan grille with compressed air; the internal fan is the only moving part and the unit has no user-serviceable capacitors or filters.

At what point does the 240 W limit appear during continuous load?

The supply delivers up to 240 W total; sustained draw above that triggers over-current protection and shuts the unit down until the load is reduced.
