Hi,
I have measured DC on computer rails (which should be +12v, -12v, +5v)
Here is the report:
NO CUTS engaged (normal VCA levels) -> +12.28v, -11.93v, +5.23v
36 of CUTS engaged (most visible VCA dump) -> +11.71v, -12.5v, +4.66v
ALL CUTS engaged (almost no VCA levels) -> +11.50v, -12.70v, +4.46v
So... Is it possible the Computer PSU doesn't have enough current efficiency?
Or some part in a computer has high power consumption?
Or maybe it is normal (I doubt it...)?
In Poland we have 230V AC / 50Hz just like in the Netherlands where the console comes from.
However all PSU's are set to 240VAC (GB).
I don't think that's the reason because regulators should handle the difference.
Thanks for the suggestion to measure voltages. However I don't know what to do next...
