The PSU is rated with 320 W. 130 W for PoE and 190 W for the switch itself.

Note that these are the maximum power draws for power/UPS sizing. For calculating a cooling budget you might want to use an average power in your scenario.

one question, 320w is the max power consumption? if I disable poe it will use only 190w? Jul 27, 2021 at 4:21

Yes, 320 W is the maximum possible power. PoE devices (PD) draw addtional power from the switch, up to 130 W. Without any PD connected, 190 W is the max. Actively disabling PoE shouldn't make much of a difference but with a tight power budget you might want to do so.– Zac67 ♦Jul 27, 2021 at 6:19
