[sdiy] Power question

Yo... Mo..Ho..  :^)

If it is a 12V regulated supply... that is correct.

If it is an unregulated supply... it is probably correct...
Unregulated supplies... when not fully loaded... often
give a higher output voltage.

If it is a switching supply... and it does not meet the
minimum load requirements (sometimes NOT a published spec)
it will work erratically, might damage equipment. Watch out.
