TP-Link PSM900-AC power supply unit 900 W Metallic

The TP-Link Power Supply Module PSM900-AC is an AC-input, DC-output power supply delivering up to 900 W with a nominal output voltage of 53.5 V. Designed for compatibility with multiple TP-Link Omada and Omada Pro switches (for example: SG6428XHP, SG6654XHP, S6500-24GP4XF, 6500-48GP6XF, S6500-24MPP4Y and S6500-48MPP6Y), this module provides hot-swappable operation to allow installation or replacement without powering down the system. The unit has a metallic finish and compact dimensions (95.8 mm × 259.5 mm × 40.1 mm) and comes as a single pack.

Advantages

The PSM900-AC supplies a stable 53.5 V DC output and supports a maximum output power of 900 W, enabling reliable power delivery for compatible network switches. Its hot-swappable design minimizes service disruption during maintenance or replacement. Compact metallic housing provides durability and fits standard switch bays while maintaining adequate thermal characteristics.

Suitable for

• TP-Link Omada and Omada Pro switches listed by the manufacturer (e.g., SG6428XHP, SG6654XHP)
• High-density PoE deployments requiring up to 900 W total power
• Data center or wiring-closet switch redundancy and hot-swap scenarios

How to use

Install the PSM900-AC into the compatible TP-Link switch power bay following the switch manufacturer’s service manual. Ensure the system supports hot-swapping and that AC mains voltage is within 100–240 V before connecting. When replacing a unit, remove the faulty module and insert the replacement until it engages; observe any status LEDs on the switch to confirm proper recognition and power delivery.

Recommendations

Use the PSM900-AC as a direct replacement for compatible TP-Link Omada/Omada Pro switch models and in redundant power configurations. Verify model compatibility and follow site electrical safety practices; do not open the unit or operate it outside the specified input voltage range.
