MikroTik G1251-0150WNA – 150W Hot-Swap Power Supply for CRS812 DDQ

Power redundancy is a standard requirement for network switches deployed in business environments, where a power interruption can translate directly into network downtime. The G1251-0150WNA hot-swap power supply addresses that requirement and is built for MikroTik CRS812 DDQ switches running in dual-power configurations. Search terms such as "redundant switch power supply" or "hot-swap PSU MikroTik" describe exactly what this module is designed to do.

The unit delivers 150 W at 12 V DC, supplying up to 12.5 A — enough to cover the full load of a CRS812 DDQ switch. Its hot-swap design allows the module to be replaced without powering down the switch, so maintenance and unit replacement can be carried out without interrupting network traffic. An MTBF of approximately 100,000 hours at 25°C supports its use in continuous, business-critical operation.

This power supply suits network administrators and IT teams operating CRS812 DDQ switches in server rooms, data centers, or distribution nodes where service continuity is a priority. Running two units in parallel provides N+1 redundancy, reducing the risk of service interruption in the event of a single power supply failure.
