My Commodore 64/Vic 20 PSUs check out
Posted: Wed Apr 09, 2014 1:10 pm
On a recent "Items wanted" thread Gavin (Ronturner) detailed how to go about checking these for overvoltage.
I'm going to be using one of these PSU to power my Plus/4 for a coming video, so I thought it would be a good time to check the three PSUs I have (enclosed black brick, enclosed white brick, black brick with vents) using the method described by Gavin.
Steady readings on the 5V line (after being on for 20 minutes) were:
5.18 v
5.07 v
5.12 v
Although being slightly uncomfortable about one being 0.18v above what it should be I'm assuming this is within tolerance, yes? So I guess they are ok. No rising voltage was detected. Voltages were at the values published when I first turned on the packs and they stayed exactly at those values for the duration.
