4 pin cpu power plug melted in the 4 pin ATX 12V2 DC connector

[↑↑↓↓←→←→BASelect]

The motherboard is a gigabyte and it's about 2 years old and the cpu was never overclocked. The pc would power on but no video. So i took all cords out to reseat them including the video card. When i took out the 4 pin 12 v cpu power plug i noticed it was melted. So i know the PSU is probably bad.

When i reseat the the 12v CPU power cord back in the connector the computer will power on and boot up and the screen comes on and loads into windows. So the motherboard and video card and ram work.

So what i was wondering is i have an old am3 motherboard would i be able to desolder the one on the old motherboard and use that to replace the one on my wifes gigabyte motherboard?

If i can what is the proper way to put it in when i go to solder it back in?

Why would you need to solder a new cpu 4-pin connector if you where able to plug in another PSU and get it working?

and if your motherboard is "melting" power cords. i'd suggest getting an RMA or a new motherboard..seems like it could be a fire hazard..

[_I_]

if its damaged, rma or replace the board

I wasn't able to plug a new one in. I had to use the melted one that was already in there.

Like i said it's 2 years old and knowing gigabyte they will blame me for over clocking it which i didn't.

I also don't got money right now to buy a new 300 dollar motherboard. That is why i was asking. So is it possible to put a new connector on it?

What kind of solder do you have? Also, do you have desoldering?

Yes you can. Just make sure you put the replacement connector in the same orientation as the old one.

Couple of options.

If the pins themselves are fine you can just remove all the plastic and plug the connector in like this. Just have to be extremely carefull with orientation.

You can replace it too, but you must have some experience with soldering on things like this, or you will have extremely high chance to do more damage. You will also need appropriate tools.

Or you can remove the plastic parts and solder wires directly to the pins. It will be much easier and safer, but will not look nice. Can use simple 4pin molex there to avoid soldering directly to PSU/loosing PSU warranty.

So buy a $50- $100 dollar one. A $300 one is charging you $200 for "cool" looking plastic shrouds, leds and branding anyway.

Clearly, the motherboard you're using now gotten or drew more power than the wire and the plug could handle. Keep using either and you could be looking at buying a $1000 new PC.

Then again it might be cause my kids like to pound on the desk when they get killed in fortnight.

That might kill a harddrive, but most of the critical PSU plugs are locked in place, and the PSU itself can handle physical shocks just fine.

Don't read if you don't want to be told how to parent.
Also, tell your kids to stop pounding the desk. You kind of want to parent them into a non-physical reaction to loss and disappointment.

its up to you, you can try to.
but it's only going to be a band-aid fix,
and next time is could kill other parts.
imo get a new motherboard, whatever cpu you have, theres a mobo for it that isn't 300+ dollars.
(not sure why you even have a 300$ mobo in the first place.....)

yeah this, not worth trying to solder a new 4 pin on, just to have it short out your expensive cpu in like 6 months time here. or worse. catch fire,

I found out that a 50 to 100 dollar motherboards are junk and very cheap built. Plus you can't find no more am3+ mobo.

Oh and i don't need parenting advice from a non parent. I raise my kids just right. So next time keep that part of your 2 cents out of it. Everyone gets mad at a video game at least once in their life and if you say you don't your lying.

Thanks i'll try this out i have a low temp soldering gun for electronics and the solder bulb to suck the old solder off. I'm just trying to get a few more years out of it till i can save up more money to build her a nice new one. I had the money but the washer went and had to use that money to buy a new washer and dryer.

Sorry for double, but what kind of soldering do you have? Also, do you have a way to desoldering easier?

It's lead solder with flux in it pluse i got a container of flux.

The solder should be fine, but without desoldering, it is your risk to try to remove it. It is limited to 10-sec dwell then needs to wait for a minute.

And it's ok to get mad. It's not ok to pound or wreck stuff as a result. Self control needs to be taught and exercised. Do you really want to raise a kid who comes asking for a loan because they threw a controller through the TV? Or worse?

What you found out was and is wrong. There are literally billions of 50 to 100 dollar motherboards running just fine. $300 motherboards are either decent motherboards with a ton of overpriced plastic crap on top, or hardened military grade designs and components for uses and situations they will never see beneath your desk. A waste of money either way. Also, beggars can't be choosers. If you have the money to waste, sure. But you don't. Lastly, your current (I'm assuming) $300 motherboard melted a plug, something I've never seen in 20+ years of working in IT, mostly with default $50 to $100 motherboards.

Secondhand places/sites are stuffed with am3+ mobo's which will be a far better solution than re-using an already proven faulty component. But hey, I'll remind you in the next thread where you trying to troubleshoot weird crashes and other issues that your motherboard is broken. See you there!
