I was wondering what would happen to a GPU that is connected to a PSU, but not connected to a motherboard?
I have a HD 6870 that started making artifacts on the monitor, so bought 2 new ones for crossfire. The motherboard only has room for 2, but thought it would look cool to have the 3 sitting there. Will it cause problems for the power supply if i have the 3 graphics plugged in but only 2 being used?
Not a good idea to have a loose powered or non powered graphics card in your case, you could cause damage to your system if theres an electrical problem , or arcing or grounding issue.
Don't do it....you may regret it!
