Ugh, I mean, measure voltages and how much they differ from the expected +3v, +5v and +12v. Up to 10% might be ok, more than this, might be not ok. Voltages might slip when the box is loaded, drives are working etc. In case your power supply is modular one, it might be possible to plug multimeter into supply's unused sockets. -- Regards, Tomasz Rola -- ** A C programmer asked whether computer had Buddha's nature. ** ** As the answer, master did "rm -rif" on the programmer's home ** ** directory.
