From computer tomograph PSU, I removed battery of capacitors. It is 12 high power electrolytic capacitors. 6 x 12000Î¼F and 6 x 8200Î¼F. All caps working ant 400V (450V surge). Total 121200Î¼F (0,12F). We can charge them to about 400V and store about 9696J of energy. Lots of energy. And lots of lethal energy. It can kill you.
