my specimen is an old 350W psu

some parts were obviously not included to save manufacturer production costs...

had to put in some mods...

remove unwanted wires...


upgrade Schottky diodes...

this is my slave switch, I use a small transistor instead of a relay to activate my 2nd psu. it's fast and has no moving parts...

using an old cdrom case for easy installation to a 5.25" drive bay...

bend metal strips for cooling fan...

almost finished!
