PC Problem

[Jason32]

Would anyone know what would cause this, the 20/24 pin connector from the PSU to the Motherboard, looks like its burnt out on 2 connectors, both sides of the plugs.

Hi Jason32.
A couple of things spring to mind.
1)a loose connection in the plug,which would cause over heating,this in turn would eventually melt the plastic between two or more pins,which could then cause a short.
2)a power surge could have occured due a component going faulty in the motherboard or in the power unit.
Check the power unit and mother board for any signs of burning or any brown stain marks,if it started in the plug,with a loose connection,you might be lucky,and just get away with replacing the plugs,if you can get the bits that is from an electronics shop like maplins.
If you are not lucky,then you might have to replace the power unit or motherboard,if these caused the fault.

Would it be worth replacing the plugs 1st then, if so, ive never done that before. Does anyone know how to do this as i cant see how the plug opens for starters.

As you can see i am no pc expert.

Hi Jason,

I don't think replacing the plugs is an option as they're not really designed for that. In teh pic is it the black or clear plug that is coming from the PSU?

The Black plug is from the PSU Ben.

If it were me, I'd buy a new PSU. My thinking is that if you make a mistake trying to prize out each of the pins on the connector and putting them into a new one you could end up frying all of your components. If you do get a new PSU make really sure you have a good connection between the plugs, i.e. make sure they are pushed fully home.

Hope it helps

Yeh.. me too. The yellow leads on the black plug show the most damage and they're 12v. Could be a simple short as suggested before but I'd be worried that's its off the 12v supply. I'd go for another PSU and pray

Hi Jason32.
You sould check for damage or signs of burning on the motherboard and in your power unit first,just to make sure they are ok.
As for replacing the plugs,assuming they are all you find thats damaged,then you need a small thin pin to push into the plugs to release a locking pin,as the pins are crimped onto the cable,and then pushed into the plug untill they lock in place,you might find cutting the plug of,and re strip the cables,then crimp new pins and sockets on the cables,you should also do them one wire at a time,so you do not get the wires mixed up,as to what goes where,you should be able to get all the bits and a cheap crimp tool from the same electronic shop.
If you do not feel confident to do the job,then try a computer repair shop.
