(burnt mobo pins), what should I do?

[Lion BItcoin Shop]

i get problem like this

source : https://bitcointalk.org/index.php?topic=102890.0

this is happen in my computer, my spec :
1. mobo B150 k4/d3
2. psu fsp aurum 700w 80+
3. polor red devil rx 470 4gb
4. corei5 6500
5. ram 4gb

the psu and motherboard is still safe for use it again? or what can i do with it ?

it is just a burned connection, if you can reconnect you are good to go

if you know how to solder, desolder and remove burned pins and solder wires to the board...this wires will connect to your psu 12v, just cut the burned wire and reconnect there

The PSU and Mobo might still work, just replace the cables and clean the burnt, however, investigate the culprit, often times this might recur again.

Find out WHY it happened before you do ANYTHING in an attempt to repair this.
If you don't that's a fire hazard waiting to happen and you might get UNLUCKY the second time around.

Your GPUs pulled way too much juice from the motherboard.

This is why we use powered USB risers, those feed the cards directly from the PSU and not from the motherboard.

You only had one gpu on that setup? 470 with 8-pin pcie power connector?

You need to replace that ATX 24 pin connector on both the PSU and Motherboard. You cant reuse the motherboard in this condition, the burnt male pins won't conduct as well as they should.

If you really can't afford a new motherboard then just solder a +12V line to the bottom of the motherboard opposite of where its burnt. Its garbage anyways.

With the PSU you need to cut the lengths of all the wires and re-crimp, basically tons of work. Better to just use this PSU in the future for an Antminer since it doesn't require the 24ATX plug.

Take it from someone who is owning and working with rig that had same exact problem - you will be fine.
Just clean the pin connection on MBO and replace the 24pin connector on your PSU and you're good to go (chance of PSU dying after what happened are weak, if the PSU is of any quality.)

That burned +12v pin happened either as a result of weak connection, or you had multiple GPU's without powered risers, so the +12v was all drained directly via MBO.
In the future be careful with those situations, they can be a real firestarters.

yes i can reconnect my psu, and now working normal, it's safe if i use it again ?

but i hope i can buy a new psu to replace it in this month.
i can't do it. i don't know how to soldier it, im not knoww anymore about electric.

Check if it's warm to the touch (the plastic). If the connection is weak due to the burn it will be warm/hot in which case it's not fine. But with some basic cleaning and soldering you could repair that.

basically i don't trust wires/pins/metals that already changed color due to burning...in my experience a burnt pin is crispy, it snaps and electricity don't pass thru smoothly specially when the power consumption increases..re using that connection will not put my mind at ease.

here is an example of a burned connection to my motherboard, with wires soldered to the board.

Burnt conductors get damaged easily, and become more of a liability than an asset as time progresses. If the color has changed, your best bet is to start planning for a new replacement.
