What is the actual limit for the 12v 5v and 3.3v roughly? I remember when i tested with a multimeter b4 i plugged one of my probes into the current port on the mm and my machine just died oops luckly unplugging the PSU for a few mins and re-powering on it worked again school boy error there
That means 11.4-12.6V for the +12V (though I prefer to see 11.64-12.36V)
And 4.75-5.25V for the +5V (though I prefer to see 4.85-5.15V)
I forget the precise numbers for 3.3V, though it has to be pretty tightly regulated. 3.2something to 3.4something I believe.
