Compatible 850W ATX power supply for QFX5100

This unit provides 850 watts of AC power with front-to-back airflow for Juniper QFX5100 and QFX5200 network switches. It uses a standard ATX form factor and carries part number 740-053352. Each unit is tested working and built to good quality standards for reliable operation in compatible chassis.

Practical limits of the ATX form factor in network

The ATX physical design limits installation to chassis specifically built for this size and connector layout. Airflow direction is fixed as front-to-back (AFO) and cannot be reversed for rear-to-front cooling setups. Output is fixed at 850 watts, so systems requiring higher capacity or redundant configurations need additional units or a different power architecture.
