There is a potentiomiter on the top of the psu (farthest away from the 8 pin input connection) "little white plastic philips screw in a blue plastic case thing usualy"
You can twist that slightly. id say anti clockwize but it depends on the way your looking at it..
just twist it slightly and measure the voltages as your doing it.
But you should probably check for dying / dead caps.
you dont need to get the 12V rail up to 12v though. 11.6 or so would be fine. but check the 5v as well as that could be going higher than 5v whilst the 12v stays below 12..
So you may end up with something like 11.4v (12v) and 5.1V (5v) that should be fine also. but try to get them both as close to the correct voltage as possible. (preferably slightly lower)
I borrowed an ESR meter and found two bad caps one 47uf 25 Volt and one 100uf 25 Volt. I replaced them and was then able to adjust the pot up to the correct voltages.
The fix seemed to easy, but it is working. Thanks for the help.
