KHACHIMO 650W PSU for Juniper Switches

This 650 watt ATX power supply is built as a direct replacement for the JPSU-650W-AC-AFO unit used in Juniper QFX5100 and EX4550 network switches. It ships new and has been tested working to confirm reliable operation in those specific chassis. Network engineers and data-centre technicians who maintain these platforms will find it a straightforward, like-for-like spare.

Replaces a failed or ageing JPSU-650W-AC-AFO module

When the original supply shows voltage drift, fan failure or simply reaches end of life, this unit restores full 650 watt capacity without firmware changes or cabling modifications. The jump is worth it if the switch must stay in production and a vendor RMA would take longer than a hot-swap install. It is not suited for builders who need a standard desktop ATX pinout or higher wattage for GPU-heavy servers.

Questions about this item

Does the 650 W unit fit the QFX5100 and EX4550 chassis slots?

The JPSU-650W-AC-AFO is built for the QFX5100 and EX4550 platforms and matches the 740-041741 slot dimensions.

What is the airflow direction and how do I install it correctly?

The AFO suffix means air flows out the front; slide the unit in until the latch clicks to seat the connector fully.
