As anyone tryed this?
I was planning building my own DC-DC Converter but one day i had an idea. Since i have some knowledge about power supply i looked into my AT power supply and noticed that if i isolate the AC transformer and insert a 12V input i could power up my PC.
I havent try it, so im asking if someone has done it or has some more information regarding AT power supply.

Well it might work only if the voltage is bit above +12v
as soon as it gets down to 12 or less the power suppliy wont work ...i recon...
but thats if you directly connect the +12 to the output of the transformer with transformer removed. And also i think you wont have -5 and -12 lines ...
i recon its easyer to build Dc converter for the scratch rather then modifing the Computer PSU.

Sorry folks, but this PC power supplies are switching types which means that the xformer you're planning to remove is just part of the switching circuit. This idea would worked for an standard linear power supply, but not for this type...dont try this at home...or at least check your insurance policy.
