The psu is not one expressly declared for use with the Pi5, or is it?
Afaik the Pi5 needs 5A plus the USB Power Delivery feature, which the
Pi4 psu does not have. The Pi4 psu won't let you run the Pi5 reliably.
So you probably need another psu after all, I'd recommend the official
one, you can never go wrong with that.
