Can the 3850 use the C3KX-PWR-440WDC or PWR-C1-715WDC

Dear all, 

Can we install the C3KX-PWR-440WDC or PWR-C1-715WDC inside the WS-C3850-12S and do they function together?

I see that the 3750X can use some or most of the C1 power supplies from the 3850 switch:

C3KX-PWR-440WDC & PWR-C1-440WDC

And I see that most of the 9300 series switches use some of the same C1 PIDs that the 3850 series is also using: PWR-C1-1100WAC PWR-C1-715WAC and PWR-C1-350WAC. 

The "Keying" system and the power connector on the back of the 9300 and 3850 power supplies seem to be the same: 

PWR-C1-715WDC:

PWR-C1-715WDC Keying system.

Backside of the PWR-C1-350WAC:

PWR-C1-350WAC

Looking forward to your reply or suggestions.

Thanks

Use the 715wac. 

The 3850-12S is a 12-port SFP switch and SFP requires a lot of power.  

A 440wac power supply is too low.  Get the 715wac instead.

Thanks Leo!

We have tested it and like you said the 715WDC is working:
