250W AT Power Supply for NAS

This 250 watt AT power supply replaces the DPS-250AB-44B and DPS-250AB-89B units in compatible Synology and QNAP network-attached storage devices. It delivers 17 amps on the 12 volt rail, 12 amps on the 5 volt rail and 6 amps on the 3.3 volt rail. The unit accepts a universal 100 to 240 volt input at 47 to 63 hertz. A 24 pin, 12 pin and 8 pin connector set is provided.

Suitable for specific Synology and QNAP models

This unit fits the Synology DS1815+, DS1813+, DS1515+, DS1513+, DS1512+, DS1511+, DS1010+, RS814, RS815 and DS2015xs, plus the QNAP TS531. It is not for builders needing standard ATX pinouts, higher wattage for additional drives, or redundant power configurations. Shops requiring a different connector layout or form factor should look elsewhere.

250 watt maximum output rating

The single specification that determines compatibility is the 250 watt maximum power rating combined with the listed voltage and current outputs. Verify that the original power supply carries the DPS-250AB-44B or DPS-250AB-89B part number before ordering.

Perguntas sobre este artigo

Does the 24-pin, 12-pin or 8-pin connector need periodic replacement?

The 24-pin, 12-pin and 8-pin connectors are fixed parts of the unit and do not require scheduled replacement.

Which output rail hits its limit first under continuous load?

The +12V rail rated at 17A is typically the first to reach its maximum during sustained operation.

How loud or hot does the supply get when running 24/7?

The unit accepts 100-240V input at 3.5A and delivers up to 250W, so heat and fan noise will reflect that continuous power draw.
