sorry if I sound as though I'm trying to be arguementative I'm not. I just don't know if you are quite understanding what I was getting at as you keep refering to problems with the psu and what I'm trying to get at it not quite fixing a problem. If I'm just having some issue with understanding what your trying to say just tell me to drop it your not changing anything.
wouldn't the AC section of a dvm be able to at least read the ripple on the line if it is able to detect a low enough voltage or is that something that would need a blocking cap in place to make it readable? I know trying to read DC would be pointless as my meter has around a .5-1 second update speed. much slower then the 60hz ripple (not counting harmonics). this actually brings up another question not quite related. anyone know of any semi decent hand held scopes? I know there are some on ebay for around 100 bucks or so that I was looking at made by valeman or something like that but not sure yet on how bad I really want one.
also I don't see any reason to chuck the PSU as I have no indication yet at least of any problems with regulation or noise that I'm aware of and is working fine as is and is within spec.
this was more of a hope of making the product work better then spec.
I do not know a lot of about digital electronics or switching power supplies as I'm sure you can see. I know though that most any ac to dc converter is going to have some rippled adn I believe that the ATX specs say what 100mv is allowable. so even if this design is within the 100mv it wouldn't be considered defective correct? my thinking was more along the lines of lets say the ripple is only at 60mv peak which should still be considered within spec but if I could reduce the amount of ripple to lets say 30-40mv by using a either a cap or a LC filter would that make any improvement to the operation of the psu even though both are within the normal operating range?
