As everyone else pointed out, it's safe (and perhaps even slightly better) to
use a higher amp power supply than is actually needed. It's the voltage
you need to be concerned about.

Think of voltage as water pressure and amperage as water volume. Hooking up a
pipe 3" in diameter to a shower won't blow the head out, but, if you took a
pipe say .25" in diameter from a high pressure pump... you'd likely blow a hole
through your shower stall.
