AT to ATX upgrade problem 2

[Accessdabbler]

Ok, have a small problem here.

My father's computer had an AT-style mobo and power switch. The case allows for both AT and ATX mobos so I successfully installed a micro-ATX mobo into the case. Unfortunately, I forgot to buy a new power supply.

Anyway, my problem is, the power switch is AT-style. The wires from the switch run to the power supply. I need to have the power switch connect to the mobo.

I was wondering, could I run the RESET switch to the POWER switch connector on the mobo and use the RESET switch like a power switch?

I need to order the P/S from an online store and need to know whether I should also order a new power switch or case at the same time (to save on shipping charges).

Simplify matters, and get a PS and an ATX case that's compatible with a micro ATX MB.

You can use the reset switch. Or the turbo switch if you don't mind doing a double press.

Just trying to save a couple bucks for my dad. If he doesn't need a case, why bother? Besides, I've already installed all the parts in the old case ('cept for the P/S).

So, the power switch just briefly trips the mobo? It doesn't need to stay on?

Yep, momentary contact, normally open. You can use a screwdriver blade. Which is what techs do sometimes to test the motherboard and the switch is suspect.

I have seen some ATX Power switches for sale but they are just a switch with a plunger. No fancy button top. The ATX power switch is a Momentary switch. When you press it it makes it allows a signal to go to the power supply to tell it to turn on. It is not a normal off/on push button. It just sends a signal while it is pressed. When it is not pressed there is no power passing through it. You can use a doorbell switch and it does the same thing.

I have seen them for sale at

Normally an ATX power supply requires an ATX power switch. An AT power switch has 4 wires and an ATX power switch has 2 wires. If you can find someone with an old ATX case that is no longer being used from an older computer, you may be able to just rip one out of that if it was an ATX power supply.

If you do not like my post feel free to point out your opinion or my errors.

Thanks all!

I decided to spend the extra money and get a cheap ATX case after all. Although I was tempted to use the RESET button I decided against it as I would then lose the ability to use the RESET button when I wanted to restart the computer.

As well, the new case will have the proper connections for the LED lights. The old case had some connectors that were 3 or 4 hole connectors when the new motherboard can only accept 2 hole connectors.

General info for your next build. The connectors can be removed from the blocks, and the blocks can be shortened with a pair of dikes. So what appeared to be a problem was a minute or so resolution.
But yes, you probably need a reset switch.
