Re: 5v rail to high
I'm still not buying it. I think it is time to name this supply and put up a schematic. These things are generally complex and well regulated supplies. True, they might need a simple load plug to actually draw a minimum current, but beyond that the 12v and 5v outputs should be right on.
It applied to picture tube tv's and it applies to switching power supplies: these flyback things are like a balloon. If you grab one part and squeeze it (tweak it), another bubble appears in a different place. The whole group of secondary outputs work together, even if they aren't on the same secondary winding. If looking carefully at the schematic doesn't get results, I would scrap this one for parts. That's my personal opinion.
