(5A)Replaced heaksink with large thik one.Replaced +12V Skottkey diode with 30A 45V high power skottkey diode. and +3.3V , +5VAdded Series inductors for +12V, +5V, +3.3V linesreplaced old fan with high quality one + Speed limit230V/110V swith now used for FAN speed control - Low/HighOld PSU cover removed, use another cover with lot of went holes.Adding new CAP,Diode for +5V SB line.Results:+12V, +5V, +3.3V rails are now more stable in variuos load conditions.Restarts in brown-out stages are stopped (thanks to large 2 filter capacitors)protected from lightning (surges)PSU running more cooler and quietly+5V SB line now hold up for 3 seconds.I will attach PICs soon.</blockquote>
