PC Power supply, w/o the PC?

[Greatscott]

I'm looking for a computer part, for the life of me I can't remember what it is called, here is what it does:

It allows a computer power supply to turn on when it is not connected to a mother board. I know Radio Shack carries them, but the sales people are only useful as comic relief, if you are not talking about a cell phone they have no idea what you are looking for.


Thanks.

I was in RS one day for some isopropel alcohol, I was getting ready to do some soldering. I went into a RS at a mall (first mistake), looked in are around the soldering supplies for the alcohol and didn't find any. I went up to the counter and asked for some, here is what I got back...
"I'm sorry sir, we no longer carry that product..."

"You are kidding, right?" I asked, already annoyed, having trugged my way through the mall might of had something to do with that.

"Oh, no sir, we are trying to be more envirnmentally friendly" The sales person said, now detecting a slight lisp.

Showing him the 60/40 tin/lead solder I had gotten off of the shelf, "You still sell this."

The sales-person just staired at the solder as if a tiny little spacecraft had just landed in my hand. The gears in my head started churning and started putting together a quick list of other stuff you'd use alcohol for. The gears in my head ground to a sudden stop, "Do you guys have stuff to clean VHS and cassette tape heads (yes, this was about 5 years ago)."

"Oh sure we do!" the salesman exclaimed, and swept around the counter, leading me to the other side of the store. As we turned in to the isle with the tape cleaning supplies I noticed the giant display, from floor to ceiling of isopropel alcohol, most of which was in the handy, but not environmentally friendly, one gallon steel cans.

Grabbing one of the one gallon cans and holding it up right in front of the salesperson's eyes, so he could read what was written on the can, "This! This is what I was looking for." The sales man studied the contents of my left hand as if another itsy-bitsy space ship had found its way there again.

Your looking for a jumper? Just use a piece of wire and stick it into the green wire spot and then attach the other end to a black wire spot.

be sure to put some kind of a load on the power supply . like a couple fans or something at least.
if you are gonna test it.

Radio Shack part# 271-0132. It is a pack of two 10 watt, 10 ohm resistors. This will put the appropriate load on the P/S to keep it on and keep the voltage up.

There is a how-to with pics stickied in the electronics section. I used it to convert another one last week. Works perfect. ;-) Here is one of the resistors installed in a P/S.

If your making a PC power supply into a RC power supply you need only a couple things.

First is a power supply that will turn on by just using a jumper from the green to any black on the 24 pin connector. If it does this chances are it will make a good power supply for rc use.

What you needed from radio shack was a pack of 10watt 10 ohm sandbar resistors. We solder these in parrelel (sp) across the red wire and any black. This creates a load on the power supply so the voltage will not dip under load from the charger.

I used a 350 watt atx power supply and I get 12.6 volts under load. Works perfectly.

If you just want to power up the power supply to check function. All you need is a piece of wire from the green to black wire in the 24 pin connector.

Lastly do no not expect any real help from radio shack unless its an old school privately owned joint.

If you are looking at a brand new computer PS to convert, check the specs and make sure it is a single rail 12V supply. With the multiple rail PSs you will not get the maximum possible amperage.
