QNAP 800W Delta Power Supply - PWR-PSU-800W-DT01

QNAP PWR-PSU-800W-DT01 800W Delta Power Supply

Overview

The PWR-PSU-800W-DT01 is an 800W Delta-sourced power supply unit designed as a direct replacement or spare component for compatible QNAP NAS and storage enclosures. At 800W, it delivers the headroom needed to sustain fully-loaded drive bays and high-throughput NAS workloads — relevant when running dense configurations where a degraded or failed PSU becomes a single point of failure. Keeping a spare on hand is standard practice in environments where unplanned downtime has real operational cost.

Compatibility

The PWR-PSU-800W-DT01 is designed for specific QNAP NAS and storage systems that ship with or support an 800W Delta PSU configuration. Verify compatibility against your specific QNAP chassis model before ordering — PSU form factor, connector pinout, and wattage rating must match the target enclosure. Consult the QNAP storage and NAS catalog or your chassis documentation to confirm this unit is the correct replacement for your system. This is a NAS storage component — not a standalone or universal power supply.

Installation Notes

PSU replacement in QNAP rackmount and tower enclosures typically follows a hot-swap or tool-less slide procedure, but this varies by chassis. Confirm whether your enclosure supports hot-swap PSU replacement before attempting a live swap under load. Verify input voltage compatibility (check your enclosure's PSU bay spec for 100–240V AC auto-ranging or fixed-voltage requirements) before installation. Improper PSU substitution can damage the enclosure or connected drives — use only manufacturer-specified units.
