Computer power supply mod (12v/5v/3v)

[silverstyle]

that is a very nice looking power supply rig. I'd give it a 2/5 difficulty rating. does require a drill and a few other small tools. just be careful when you have the case open. very high voltage in there, even unplugged. I always stress safety, especially when high voltage capacitors are involved. I might build a nice power supply some time this week. my grow is in need of one.

Agreed. However, they do explain how to discharge it relatively safely using the 10W resistor in the above article, so that should remove some of the danger.

I found it relatively easy after reading that article to dissect the power supply, modify it as necessary to safely connect power to my various devices on separate, very simple circuits so I could later add a relay board or switches in order to automate everything.

I'm still interested in this. I pm'ed you the other day. I'd like to share some automation ideas with you. mine's been running well for the last month, but still improving and expanding.
