Sig Rig Destroyed Power suppyl Failure? (epic burning plastic pics)

post #1 of 18
Thread Starter 
Ok so i still dont know what happened, but when i smelt burning plastic coming from my rig i had to investigate.

This is what i found....

The 24pin on the motherbaord


The 24pin that plugs into the Motherboard


The 24 pin that plugs into the power supply


The Power Supply


Needless to say im wondering what the hell caused this????

You guys think there is any RMA here the power supply is 4months old.

The motherboard has no warranty, So im thinking ill have to get a new one that supports 4 graphics cards....do they make them on P67 or z28 systems?

Im pretty sure my tax return is gone now

Dayum! That's nasty.

Overload or short circuit on the +12V on your motherboard ATX connector. Possibly caused by running tri-SLI 480s without auxiliary PCIe power to the motherboard.

I would think judging by these pics the power supply manufacturer should also replace the MOBO as its down to them if it was the PSU that failed in a big way,

Had a 4pin molex feeding into the PCIe slots.

You think silverstone will RMA this 1500W?

I honestly dont care about the board too much because i can just upgrage that, but there really isnt an upgrade for 1500W

No, that's the +12V.

They should RMA it as long as it's still in the warranty period.

Yee haw I can smell the plastic burning from here. That doesn't appear to be a problem with the PSU and I'm sure it's still fine, you just need to replace the plastic. The connection just couldn't handle the current. And a 4-pin for the PCIe slots? Don't the cards have 6-pin connectors?

I'm not sure a single molex has given enough extra +12v to the GPUs on that board. If you must replace it, then look for one with two aux power connectors.

Based on one of the photo shots, I can clearly see what happened.
The plug from the PSU has a pin that had somehow gotten pushed back upwards into the plug from the PSU itself and you had a bad/poor connection to that pin. I've seen these pins get pushed in before and even had that happen once but fixed it.
That made it get hot where you see the worst damage and of course led to the meltdown. It's possible the board itself may actually be OK if you can replace the plug-in connector on the board. All you'd need is a donor board to get the plug connector you'll need to do this and be sure you orient the connector plug correctly when you do this.
Yes it's possible to replace it and I've done such a thing once or twice before but you have to be careful about how you go about doing it or you'll make things even worse.
If the board is truly dead, you can't hurt it any worse by trying.
