  • TypeAT
  • 700W output delivers reliable power for server workloads

Compatible QNAP 700W power module

This 700W server power supply replaces a failed unit in compatible QNAP NAS systems. It uses an AT type design and is built by Delta for QNAP INC. The module is supplied new and carries the manufacturer part number PWR-PSU-770W-DT01.

Continuous 700W delivery for multi-bay arrays

The unit sustains 700W output under sustained load rather than only in short bursts. This steady capacity keeps multiple drive bays, expansion cards and processors powered during long backup or virtualisation tasks. Delta engineering targets stable voltage rails across the full duty cycle.

Verify chassis slot and part number match

Before ordering, confirm that your QNAP chassis accepts this exact module form factor and that the MPN PWR-PSU-770W-DT01 appears on the vendor compatibility list. Check whether your system requires a single or redundant pair. Ensure the AT type connector matches the backplane.

Questions about this item

How much power does the 700W Delta module draw and dissipate when the NAS runs continuously?

The unit is rated at 700W output; actual draw and heat depend on the connected NAS workload and ambient temperature.

Which QNAP chassis or backplane must I already have for this AT-type supply to fit and connect?

This AT-form-factor module is designed for compatible QNAP rackmount or tower servers that accept a single 770W Delta power supply.

Will this supply work in a 2018-era QNAP server that originally shipped with a lower-wattage unit?

First listed in 2018, the 770W Delta module fits supported QNAP models from that period provided the chassis accepts an AT-type single supply.
