Please specify the power supply(ies). I know a lot of bindings haven't, 
but many panels have more than 1 supply and just relying on simple panel 
doesn't distinguish whether the panel has 1 supply or you didn't check 
and it has more than 1.

Ok, I'll specify the power supply. And I'll add an example, it's always
nice to have one.

Thanks.
