You’re very welcome.
I just happen to be preparing to build a power supply for a RasPi this holiday morning so RasPi power topics are on my mind right now. BTW - To all the veterans out there, Thank you for your service!.
The easy way is to test your cables is with a RasPi.
The only bad thing that can happen is the RasPi crashes and corrupts the uSD card. But that can be fixed by simply writing a new copy of the OS image to the card.
All RasPi’s have a built in power check to let you know of a problem before it crashes.
So go ahead and try all your cables and watch for the little lightning bolt icon to show on the monitor. If it shows then the cable is not suitable and might lead to crashing if you run the RasPi harder.
