Units connect to power supplies/a power supply?

How should I write in the following case?:

There are three machines (Unit A, Unit B, and Unit C).
Unit A needs a power supply.
Unit B needs a power supply.
Unit C needs a power supply.
Three power supplies are necessary. These machines cannot share a single power supply. These power supplies are all different in supply voltage and type.

In the above case, is the following expression okay?:
1. Unit A, Unit B, and Unit C need a different power supply each.
2. Each of these Units needs a different power supply.

The verb require is a little better than need.
