Schematics of PC Power Supplies
All schematics are drawn by myself and for information only.
They might be helpful when repairing such a power supply.
All power supplies have about 200W and the typical +/-5V and +/-12V outputs.
The common principle is a half-bridge switched by bipolar transistors not FETs
and the TL494 switch mode controller IC is used.
The format is pdf and can be seen with any Reader, the paper size is DIN A3.
Some component types in the schematics are certainly wrong or unidentified,
because I simply couldn't read the type names.
The file size is about 150KB.
