Steve are you talking about a power supply or driver? If the driver runs off 120VAC then obviously you don't need a power supply but some drivers already discussed require a lower voltage DC supply so you need a separate power supply. The driver must be constant current but the power supply only needs to have enough power (watts) to run the driver(s). The voltage of the supply is also important and dependent on how many LEDs are in each array for each driver.
