I modified the Bench power supply I built before instead working on the previous one.

Four modifications I made which mentioned on the wiki document()
- 50 ohm resistor between Green wire and ground wire that acts as power switch*
- Shorted one pair of +3.3V wires*
- external fuse holder (5x20)
- 1A load on +5V rail

What a mess! It was the level of my workmanship in electronics two years ago.

external fuse holder (5x20)
![cdsc_0044.jpg]( "cdsc_0044.jpg")
50 ohm resistor between Green wire and ground wire that acts as power switch
(The wiki document recommends 47 ohm.)

1A load on +5V rail
I built the 1A load using two 10W 10 ohm resistors in parallel. And I connected red and black wires to it.

Checking voltage
+12.31V

+5.15V
