Anyone with Mobo RMA experience? SUggestions for problem?

post #1 of 5
Thread Starter 
I have a rampage III extreme motherboard with 3 gtx 580's in tri sli. A couple nights ago my computer just turned off and I smelled burning. I thought it was my power supply so I RMA'd it and got the new one. Installed it and I got the same problem.

SO I took out the motherboard and saw that the third PCI slot had burned marks all over it and one of the chips below it was fried. I'm not sure how it happened. The side panel is completely open I have a ton of fans on everything. Everything was cool and open so I guess it was just a freak accident. This is the first time in my life of 10 years building computers that this has ever happened.

I called Asus and the rep told me he needs to run the RMA past his supervisor to figure out if I voided the warranty in some way and he will let me know. Could this be true? How could it be my fault at all? It just burned out on its own.

Also, I was wondering if anyone knew whether or not the slot that burned out could have killed the video card in the slot along with it? Any opinions would be much appreciated.

It's fairly common to see boards shorting or burning when using multiple "power hungry" cards. That is why some companies add an auxillary port somewhere on the board to help stabilize the power draw from those cards.

Sounds like in your case it drew too much from the PCIe slot, causing the last slot to burnout.

If your cards were at stock, it shouldn't be your fault.

By any chance did you have a molex connector plugged just above the top PCIe x1 slot?

Actually, yes I did. To power the mother board I needed the motherboard power connector, 2 8pin connectors and 1 4 pin. The 4 pin was a molex. Was that the reason?

Yeah if it burnt out with that molex plugged in, I would definitely give Asus a call or chat. You didn't really need both 8-pin connectors as that is only needed for extreme overclocking (ex: DICE, LN2, Helium, etc.) and only provides more juice to the CPU socket.

Yeah, I did. They said it was my fault because I overclocked the board. I never overclocked anything. One of the chips blew out underneath the bottom PCI-e slot and it was because of their board. They gave me and RMA and told me that when they received it they would determine the cause and whether I would have to pay or not. Even though I didn't do anything they will probably say it was my fault and make me pay or something. I've been using Asus products in every build I ever did and never had any problems with them until now. I guess I'm going to EVGA they try and rip me.
