| How Many Amps are Too Many? |
In a regulated power supply, such as these switchmode power supplies, amps don't matter as
long as you have enough. Excess amperage is just held in reserve. An analogy is "doubling the size of your water heater won't
make your shower pressure change."
Unregulated power supplies (such as wall-mount transformers) are different, since
they are built to supply a specific voltage at a specific amperage. If you draw less amperage the voltage will go up.
In conclusion, a higher current rating won't hurt your appliance as long it is a regulated power supply. For unregulated power
supplies the specification should be close to the original. |
