QNAP PWR-PSU-700W-FS01 700W Hot-Swap Power Supply Unit
Overview
The PWR-PSU-700W-FS01 is a 700W replacement power supply unit from QNAP, designed to restore or expand redundant power capacity in compatible QNAP NAS and storage systems. At 700W output, it delivers sufficient headroom for drive-dense enclosures running multiple high-capacity HDDs or SSDs under sustained read/write loads — scenarios where an undersized or failed PSU becomes the single point of failure for your storage infrastructure.
Compatibility
This PSU is manufactured by QNAP for use with select QNAP NAS enclosures and rackmount storage systems that accept the FSP form-factor module. Verify your specific chassis model against QNAP's compatibility documentation before ordering — PSU form factors and connector pinouts vary across the QNAP storage line, and not all 700W-rated enclosures use the FS01 module. This unit is not a universal replacement; confirm chassis compatibility for your network-attached storage system prior to purchase.
Installation Notes
Installation follows standard hot-swap PSU procedure for supported chassis: power down or hot-swap per your enclosure's redundancy design, align the module with the PSU bay, and seat until the latch engages. Consult your enclosure's hardware user guide for bay-specific insertion force, locking mechanism, and any torque requirements. Incorrect seating can prevent the system from recognizing the unit. Refer to QNAP's power supply replacement guidance and your chassis service manual for step-by-step instructions specific to your model.
