Hi guys,
I have a Manli GeForce 9600GT and a Biostar HD4850 graphics cards that have both the same problem : they short the PSU as soon as the PCI-E connector is plugged.
Now upon inspection, I've noticed that there is continuity between all the pins of the PCI-E connector on both cards between the GND and +12V. I'm pretty sure it's not supposed to be this way as I have made the same test on my other video cards with a PCI-E connector and none of them show continuity between the GND and +12V pins. And that's on at least ten other video cards, including two other 9600GT and two HD4850.
There is no sign of damage anywhere.
I've checked all mosfets and caps, they're all good. Could this be internal to the board itself ? Two layers could be in contact ?
What could I check now ?
