12V 2A power supply okay for Arduino Uno?

I've got an old 12V 2A center positive power supply lying around... from everything I've read this sounds like it should be fine, but just want to double check before plugging it in. Thanks!

Yes, should work fine as long at it is 12 volts DC and not AC.

Yes it is AC in and DC out… thanks!

The only thing I would caution about higher current supplies is that they are far less forgiving of shorts and incorrect wiring as they can supply a lot of current.
