Have a look at table-3 in this link. 560w when using one PSU and 1440 when you using 2 1100w PSUs (which is your case).

In one of my C9300-24UX deployment, I have redundant power supply PWR-C1-1100WAC-P, show power inline output shows 1405.0 as available power, As per product documentation this power supply can give 560W only, so I am bit confused.

Hi!
The whole switch is supposed to privide 560W PoE Budget as per datasheet:
Do you have a Stack?
Could you post the outputs of the following:
#show power inline
#show switch
Best regards

Thanks Reza.
This concludes adding secondary power supply increases overall POE budget.

As of now, according to Cisco, only chassis-based switches (e.g 9400, 6500 etc) can combine power of dual power supplies. But not for the stackable ones. You however can combine the power if you use stack power module.
