Wonder if anybody with good knowledge of this can give some advice:
- Is it better to use a single PSU, converting 12V to 5V where relevant
- Or would using two PSUs + an extension chord be better
so it seems the 12V to 5V conversion is pretty efficient. Both seem to draw around 5.47 Amps at 12V (= 0.292A at 222V).
That said the PSU I'm using is not rated to 6A it needs; so I'll look at upgrading to 12V 6A - or maybe even a 8A to have a wide margin.
I also wonder if the inline switch I use might need to be replaced to something else.
It is connected via 5.5mms barrel plugs between the PSU and the rest of the system.
It heats quite a bit and I replaced it twice after a few months. My guess is that it's not rated to 6A.
But I keep it since it allows me to have a single switch easily accessible at the top of the cabinet.
The switch is something like this:
