Description

QNAP PWR-PSU-550W-FS02 550W Replacement Power Supply

Overview

The PWR-PSU-550W-FS02 is a 550W replacement power supply designed for QNAP high-capacity NAS systems. When the factory PSU fails or degrades in a production NAS environment, swapping in a genuine replacement unit restores full rated power delivery without requiring a full chassis replacement — keeping your storage system online and avoiding the data-availability risk of running on a compromised power stage.

Compatibility

Designed as a direct replacement for the QNAP TVS-H1288X and TVS-H1688X NAS systems. These are high-bay, high-drive-count units where sustained 550W delivery is necessary to support full drive populations under load. Do not install in QNAP units outside this series without confirming form factor and connector compatibility against your specific chassis model.

Installation Notes

Power down and fully disconnect the NAS from mains before removing the existing PSU. Verify the replacement unit's connector layout matches your chassis bay before seating. QNAP TVS-H1288X and TVS-H1688X chassis require the FS02 form factor — cross-series PSUs are not interchangeable even at equivalent wattage ratings.
