850W ATX supply for Juniper QFX switches

This 850 watt ATX power supply is built as a direct replacement for the Juniper JPSU-850W-DC-AFI unit used in QFX5100, QFX5200 and EX4550 network switches. It delivers the same rated output in the same form factor so the switch powers up without modification. Each unit is tested working before it ships.

Replaces the original Juniper 740-053638 module

The supply is intended for administrators who need a spare or replacement for a failed factory unit in a compatible Juniper chassis. It is not suitable for standard desktop ATX builds or for switches that require a different wattage, connector layout or airflow direction. Buyers should verify the exact part number against their hardware before ordering.
