How can I know if my Xbox Series S is receiving enough power?

its either on and stable or off.

Xbox one s or series s ?

If xbox one s then no it has to run thru xcloud as the hardware isn't powerful enough meaning non subscriber accounts can't use it

Series s can run it natively thru home share

Your only options are to purchase an Xbox Series X or S or if you can, get a powerful PC good enough for the game.

It could also be that your console is not getting enough power if it's shutting down.

Could you make sure your console is plugged directly into a wall outlet and not multi-plug extension cords and the like?

With the Xbox One S the 'power brick' is internal and can handle a range of voltages, but there still might be something that is not being handled correctly by receiving the different power rating of China compared with the US.

Let us know how you get on with that.

only series s and x and pc, the one x is not powerful enough to run it properly.
