Powering your computer

[TheMovement4]

Alright, ill try to explain this clearly, but I dont really know what Im talking about, so here it goes.

I have a power switch, same as the one on the back of your PSU. Alright I was going to put the switch on my case then run two wires to the 24pin connector that goes to your mobo. I was going to wire it to the 2 pins that lets you power your PSU with out connecting it to your mobo.. again if that makes sence. Its like using the paper clip method.

Ok going on, I was going to have a wire go to each pin and then back to the power switch, so when you turn the switch on.. your PSU kicks on.

Now I know this works, I tired it today. But my question is, will this work when I plug everything in on my pc?

Now ill expand on that, Imagin your computer just as it is now, a power cord to your HDD, one to your CD Rom, ect, ect. Now what im saying is, instead of having a power button, (so this whole thing is bypassing the power button) I plug a wire into the two pins that lets you run your PSU with out connecting it your mobo, but wait! You are connecting it.

So now.. and I know this is long, so sorry, you have a wire coming out of the pins to the switch. Now, the computer is off, with NO power button. I flick the switch that is wired to the two pins, and the computer turns on.

Will this work just as having a power button? I know it works, again I tryed it on my old computer, but im not sure if it will be stable.

So you are saying instead using the plug on your mobo which the wires go to from the swtich on front of your case instead wiring them straight to the mobo power connector. Right. Yeah it sounds ok.

Or are you using a 2nd PSU to power other stuff in the case. Then a mobo molex jumper is fine.

Its a bit confusing though what you actually want.

I know, im sorry, ill open paint up and draw something lol, brb.

ok heres what I got:

That would be the front of the case, see the power button and the switch? I wont wire the power button, so its just there.

And now thats the psu, it will be in the case, just didnt want to make all that. The two wires will run to the switch, th at will be on the front of the case.

No I will only have one PSU, not two.

Im just wondering if this is safe...

[simon275]

Yeah it seems fine. But its normally done with running the Switch to two pins on the mobo.

[TheMovement4]

I know, but sinces its a switch.. idk if that would work. Because the switch would be on the ON postions, thatd be like holding the power button down, meaning it just turn your computer off, or worst..

But I think ill be doing this, unless otherwise.

[simon275]

Just use a monetary switch. Like a sping loaded rocker switch easy.

[TheMovement4]

My dad has an old power protector, when the power goes out it turns off. And the way to reset it is to flip that type of rocker switch.. but I cant use it. Maybe I could replace the one I have with that one? Idk its late...

[simon275]

You could just buy a cheap one and wire it in from like circut city or an electronics componet supplier wont cost more than $1. You can probably get 5 for that.

I'd use the power pins on the mobo. Less hassle and less chance of somthing going wrong. Take a trip to radio shack or an electronics store or automotive store and see what they have for momentary switches. You'll probly find a switch better than what you were going to use and like simon said, they are a dime a dozen.

it wouldent work to power on because the mobo startup wouldent happen. it would only work in the sense that it would prevent your computer from turning on and turn it off in the manner of unplugging it from the wall. This is generally considered to be a BAD IDEA. dont forget that the PSU also powers other things which might have problems from not being powered down by the mobo. (like HDs)

[TheMovement4]

Yeah Im taking your guys' advice and and just getting one of those rocker switchs and using the mobo pins. Well thank you all for your help.

[Maz]

hmmm interesting, i believe it would work. the mobo sends a power good signal to the psu which is essensially just shorting those two wires together. when the computer is off nothing needs power. (do you break it when you unplug it from the wall? no.) if you have an older pc around, try it on that first. you dont want to make a first try for wiring have big consequences if you fail.

good luck, leave no regrets.

I did try it on an older computer, powered up fine, ran fine. But like you said, I don't want to take the risk.

While your idea makes sense to me, the whole reason behind doing it is complete bupkis, especially if there's a mobo in the computer already. Here's the holes in your idea:

The switch has to be momentary, otherwise the PSU will turn on then off agian.

If you have a motherboard in the computer, bypassing the power button is pretty useless -- the moment you give the computer power everything will spring to life, it doesn't really matter how you get the signal.

Save yourself the time and effort, just use the power button in your computer. It's damn near the same thing (It's just in a different location and made easier) and it's already there.

I know, I going to use the pins on the mobo.. There isnt going to be a power putton on my case anymore, its being taken out. Theres ones at radio shack for like $3 then $5 for shipping. Theres an option to have it sent to the store but it doesnt work...

Keep in mind that the connection has to be momentary instead of constant.
