Burnt Pins - 24pin ATX Motherboard and Psu lead

Unread postby AzzA82 » 15 Jul 12, 10:07 pm

Has this happened to anyone here ?

I was swapping graphics cards out the other day to test an old card b4 i gave it to a friend. Went all good no problems reinstalled my 580's and went about my day.
The next day my pc just went black turned off, I pulled it apart and seen the burnt pins ( 12v ones in the top left hand corner ) had a go at cleaning them up and tried turning it on.
It works :D , sort of maybe once a day i'll have to do the same thing to get it going again. I'm just trying to limp it through for a fortnight and i'll just make the jump and upgrade.
Been having that itch for a while now anyway.

As for the cause i'm guessing i may have bumped it and made a bad connection, since after cleaning it runs just fine its just fairly mangled now and isn't an optimal connection anymore.

So 2 things anyone got advice on replacing psu atx connectors I've never done it but i'm gonna try since it's a 1000 watt antec, and secondly i noticed some new motherboards like the asus rampage formula IV have extra pci-e power on the board on top what the slots and cards have themselves. Is this because of problems like what I've had ?

Can you take a photo of the burnt pin? I'd be very hesitant to use anything that is burning out like that!

As for the extra power on some mobos, that's for power hungry CPUs, not for things plugged into PCI(-e) slots

for things plugged into the pci-e slots, generaly power hungry graphics cards in sli/xfire there will be a molex connector up near the top of the 1/4x pci-e port.... its for supplying more power to the cards than can be supplied through the pci-e lanes...

if you have a burnt out connector, and the psu is fairly new and under warranty rma it. please make sure you run your equipment through a decent powerboard with overload/current protection inorder to avoid spikes and the like venturing into your computer..

if you cant replace the connector and you believe the psu is 'ok' see if it can be warrantied, if not, i woul dbe shopping for a new psu

Cleaned the pins with a really small jewellers file , and the blew them out with a compressor ( Power off and unplugged obviously )

I've taken my 580's out and am only running my 480, since im gonna upgrade im not too concerned if the rest doesn't make it ( I know i sound really depressed about a rebuild :lol: )

I wasnt speaking about the 8pin or 4 pins ones up near the cpu but about the 4pin ones right next to the pci cards on the more upper end asus boards. I was reading they were for more juice in sli and cf setups plus extra general board power ( they are optional to connect apparently ) . Only reason i was curious, when looking into the burnt pins problem i found quite a high percentage of users with SLI setups having this problem.

Yea the psu is out of warranty, and i run everything expensive through surge boards ( and they boards are still active ) . The psu im willing to repair i used it on another computer yesterday and its fine, the mobo pins are my real problem i dont think i'm capable of changing the socket on it.

Those two pins are the +12VDC ones, so yes, drawing too much through a SLi or CF setup could cause that, though the cards should be using the own additional power for the most part!

The way these will be burning out is that the system is trying to draw too much power for the connector, it heats up and causes the surrounding plastic to warp and deform, and other bad, bad stuff. This is a giant fire hazard!

If you want to keep on using the PSU, that should be ok, provided you change the plug (to do this, you'll need a de-pinning tool and replacement plug. Modding stores should be able to get you these.)

Motherboard on the other hand is probably toast, if the plug is gone than it's possible the tracks are gone/going as well, and whilst it is possible the change the socket, you can't see the damage to the tracks and can't fix it.

I take no responsibility if you continue to use the equipment and it burns down your house or if my advice does any further damage.

Maybe faulting voltage controllers, or caps on the MOBO .

*edit zomg computer is burning up!!!>!>!! on the netbook now.

need a new mobo and psu and probably a new cpu because no local stores seem to sell 1366 pin mobo anymore. :(

Could he claim the replacement of the parts on his home & contents insurance (assuming he has insurance).

:lol: Love the box test bench im guessing airflow is no problem

That's my problem too , not many 1366 boards around and the ones i did find were overpriced was near half the cost of buying a new 2011 board (gigabyte ud3) new cpu and quad ram

So i'm thinking going a
ASUS Rampage Formula IV
i7 3820 ( would love higher but this a quick emergency build have to do for now )
4x4gig G.skill Ripjaws 2133mhz 11-11-11-30 ( Not the best timings but im not making the same mistake i made last time 1600mhz sticks were a pain when going for a high oc )

Insurance i dont know i have but im assuming like warranty as soon as you say "Non standard water cooled motherboard" they tell you were to go ...

But all in all this board got flooded 2yrs ago when my water cooling failed flooded my gtx 480 and gtx 280. Pulled it apart and dried them all and all of it survived bar the 280. So to even get 2yrs out of this board im pretty content.

Update good old PCCG is gonna RMA my PSU nice they even offered to get the motherboard done 'cept i butchered it to fit my water cooling :roll:
Never realized Antec do 5yrs warranty on their high end power supplies i should read manuals more often
My new parts are not here stupid AAE paid express ordered Tuesday night, but its not coming till monday it sat in the melbourne depo for 3days :evil:
I bloody ordered via snail mail some gear from GAMMODS and it was here yesterday via AUST POST off all people.
Oh well current pc still kicking for guild wars 2 beta at least.

Damn that sucks, least the power supply is being replaced they are not cheap.

I placed an order from PCCG, (I'm in Vic) via snail mail, saved a lot on postage too for the size of the parcel, it was sent at Thurs 19th July 3:42PM and arrived the next morning 20th July at 8:45 AM, :shock: you must have got a slack driver.

Yea pot luck hey, i paid express 'cause i really really wanted it by the weekend weekend project, even bought a new power supply locally, since PCCG and AAE usally get stuff here overnight.
So i got a Antec High current gamer 1200 was the only PSU in backwards townsville in stock and over 700 watt, Oh well Future proof, efficient and apparently TOP DOG :lol: Guess i'll Ebay the 1000watt True power when it gets back.
Oh well next week I'll post up some benchies, i really wanna see how far i can push the i7- 3820, i had the i7-930 post and bench at 4.8ghz ( It was a really **** chip , mine anyways needed massive amounts of vcore , even at 3.6ghz i needed near 1.42 to be stable, the standard 2.8ghz vcore was 1.29)

Was extremely disappointed with it, the build b4 Q6600 was hittin 4.8ghz on 1.35vcore, I know just numbers it just feels better epeen and all, but the I7 was way faster in the real world.
