Have you ever wanted to see what's inside a computer power supply?
Well here's your chance.
P.S. this is my first Instructable so I hope it's good enough
Caution: Don't do this at home unless you know about the risk of shocking yourself even after turning it off! If you want to take that risk, Always discharge those 1 or 2 large mains filtering capacitors by jumpering the green wire in the 20 or 24 pin ATX plug to a black wire in the same plug while the PSU is unplugged. You should hear a click. Remove the jumper and disassemble.
You might want some rubber gloves to keep your hands from getting electrified

Step 1: A look inside the power supply
This particular power supply has a un-switched output meaning the output always has voltage. the rectifier down the bottom of the psu uses 4 diodes to change AC to DC. On the primary side of the board, we see the X-Y caps dominate the space. They serve as the mains filters. Lower down, just to the right of the torroid, are some yellow rectangles. These are caps designed to help the power supply handle surges and inrush current. To the right of the fuse is another inductor (the white thing) used for more mains filtering. It may actually be an isolation transformer. In the middle, we see the heatsinks. attached to them are the mosfets, used to raise the frequency of the AC. This allows the transformers to be smaller, and results in less ripple to be filtered out. On the upper right is the voltage regulating parts. On the heatsinks are more Vregs. On the upper right is the secondary side, with its filter capacitors and inductor.
