Based on the current info I have, and this is limited to the reports I see here specifically. The connectors are not faulty, however some units after repeat use are developing a problem where the pins become lose and do not make proper connection with the pin outs form the PSU. I will make sure that anyone that has a card with this original connector, can report the problem to me directly or on here and I will make sure it gets fixed for you ASAP.
