To clarify: I meant that one should check that a motherboard / PSU
pair are compatible before connecting them and applying power,
not that one should check PSU voltage and current. Yes, a "smart"
contemporary PC power supply will behave differently when under load,
and so must be tested with something more sophisticated than, say,
a basic multimeter.
