I am preparing to replace several 5V switchers for USB port expanders with
a common Lambda 5A 5V open-frame PS. We may not be able to do this for
long; efficiency regulations actually forbid making (and maybe selling)
linear-regulated (i.e.: dissipative) power supplies

"The wall warts were extremely noisy and generated so much hash I was unable
to listen to any AM radio in my entire home."
I replace such noisy supplies with 25 cent linear supplies of the same
specification bought at a thrift shop.
