pc power supply

Thanks for the info. so pc psu is not good for powering lasers. I guess I will use a driver with my new diode. Will this driver work???
DealExtreme: $1.99 18V 5W Cree Circuit Board for Flashlights (16.8mm*5.5mm)
or this
DealExtreme: $4.26 3W 19-Mode Universal Regulated Circuit Board for Flashlights
I want to have my diode at 4.2volts at 1amp....

The power supply supply case is a common ground. No, you shouldn't be getting a tingle.
I've had many running with the bundle faked into thinking it was connected. I've touched more than 1 case at a time and nothing. Since its age, you should check for corroded or oxidized mounting screws to the circuit board. It's probably picking up leakage from the board not having a good ground.

totalhealthguide copied this crap answer from PC Power Supply Buyer's Guide. this is a spam account.. can we get this guy banned? check out his other lame posts

hi, when i converted my old AT supply i used this site as a guide

Converting a PC Power Supply

also used these as references (not trusting one source of info out there )
(this one gives more of an idea of the differences between atx/at mod
PC Power Supply

and

How to Convert a Computer ATX Power Supply to a Lab Power Supply - wikiHow

hope that helps

heres mine

Fivos, the links for the drivers you gave out are for flashlights and won't work with diodes unless you take all the components off and solder your driver to that driver to use it inside a flashlight.

I recommend building a basic LM317 driver or buying a good driver such as a FlexDrive and not a cheap driver (in my opinion).

If you do add a capacitor, DO NOT FORGET TO SHORT IT!

For finding the resistor value: 1.25 / Amps (Example: 380mA will be 0.38) = Resistor
