Hello,

It depends on your model and the peak power consumption/maximum power associated with it. Based on that you can choose which power supply suits you best. If you share the model we can recommend of course.

Thanks

have you got the chance to read the posted above link

Hello,

Thank you for sharing. Please see attached image. In your case, the switch typical amount of power consumption is 374.5W and the maximum power consumption is 694W which is the amount of power you must provision from the power source as input to the power supply and switch for peak conditions. Although 650W PS would be sufficient for regular switch work at some peak consumptions there might be performance degradation as well as some other issues. That being said we will recommend using the 1200W HVAC/HVDC just to stay on the safe side.

Thanks
