Hi Team,
Greetings!

We have  a ISR4331/K9  AC version  Router and Can we use PWR-4330-DC with this Router ?

Thanks,

If that is internal PSU  - i am afraid you can do that 

check hardware installation guide :

Hello @ShiyamMohomadSiraj 

The ISR4331/K9 router is designed for use with AC (alternating current) power, and the power supply PWR-4330-AC is appropriate for this model.

If you have a PWR-4330-DC power supply, it is designed for DC (direct current) power input. Attempting to use a DC power supply with an AC-powered router or vice versa is not recommended and may damage the equipment.
