I purchased 7 Dell computers they were sent with 7 after market targus power supplies. 6 of them had the adapters missing and not all were the same type. Was supposed to have 2 hdmi ports but has d ports. I paid an IT person to install all units and he could only install one. Now 72 hours later that only one has failed. We received the adapters for the  Generic Taurus powersupplies. Multiple power supplies are failing.  Since I was buying a Dell computer I have a reasonable expectation that I was getting a Dell power supply. The generic power supplies fail regularly. I Purchased 7 units I can not keep revisiting this issue. The appropriate resolution is for me to get 7 Dell power supplies.
