Yup. Many years of running things of bench PSUs have taught me this.
That's not to say I've never fried stuff, but usually only when I've
inadvertently wound it up to +/-30v and really cooked stuff. Current
has never been a problem (although running my fully loaded Acorn Atom
did make the bench PSU heat up quite a bit).

Doc... this is a BAD idea... I've fried
numerous devices by using the
wrong power rating... even if it was only 1mA off. The voltage almost
never matters... as long as the power is correct. Hope this gets to u
before you fry your machine.

That's opposite everything I was ever taught. As long as the voltage
and DC polarity are correct, and the power supply provides at least
enough amperage for the device, the device itself determines the amount
of power it draws. The big worry is that a slightly under-amped PSU can
toast itself trying to keep up.
