Default Tesla m40 burned my motherboard VRM

Hi Folks:

I just bought an used Tesla m40 12 Gb used at ebay. Thing is I bought an nvidia CPU to pciex power adapter. Two wires to one. So I just plugged those two pciex and the card in pciex16 slot. It started all good. The computer booted, the linux driver installation program detected the m40. So I start to install the driver from the internet since the installation program told me it was on the linux channels. But then after a while (I was browsing the internet) my computer shot down and went into magic smoke. Thing is the VRMs burned. It has discrete mosfets (asrock z77 extreme 4). So right now I am getting a new board (maybe will try to replace the mosfets on the old one) but I would like to try the Tesla as they are lost now. I am worried I could burn the new board too. So I am wondering how could I test it before putting in the new one. I am worried the card is ok but the driver turns on some circuit that is shorted or consuming abnormal levels. What are your thoughts?
