in psu 101 he said 24 is the minimum on the =12v rail. Power users shouldnt be considering anything short of 30. he might wanna be safe. 34a isnt an overkill the higher the better, why not.
because you'll pay way to much.. the PSU101 are just guide lines.. and 30A is only written there, because the autor wants to be safe..
and yes,.. i know a bit what im talking about.
