As a rule of thumb, DC power should be within 5% of the nominal value.

As a DEC reality, DC power should be not less than the nominal value,
nor more than 5% above. In other words, -0%, +5%. I learned that
from field service when they were troubleshooting a cranky DMC11. The
cause was that the power (+5V in that case, I believe) was about 3%
below nominal, and the device wouldn't work reliably then.
