See the below details.

I suspect you maybe on Guest, can you confirm that by running this below command,
tmsh show sys hardware | grep -A1 Platform
If it says Guest, you may not able to see power/fan status. Only if its a hardware, you would see.
Also if it was a hardware, I'm positive you should have atleast seen Down or something else. But since you get blank, I'm suspecting it could be a guest machine.
You could be facing some bug or matching some specific condition.
I recommend you in future questions to provide more information about your environment (like release, platform or command output), this could help us to understand what your issue is.
Anyway, if I were you I would try to search in your device stats (psu, fan) if this information is represented correctly or not. I don't remember exactly the table name, just search for it with this command:
tmctl -w 300 blade_temperature_status_stat
Thank you for your reply, I try to search stats with the commands you wrote. But there is no information about the FAN or PSU on the table. As you stated it could be a bug or something.
