What are the risks of using a 24-pin to 18-pin adapter to connect the EVGA power supply to the motherboard? I used the same power supply in a Dell Optiplex 7020, which requires an 8-pin connection for the motherboard, so I used a 24-pin to 8-pin adapter for two years. However, I eventually encountered some issues with the motherboard, which stopped working. I had to buy the Z230, and now I'm not sure if the problem was caused by the adapter or not. That's why I'm considering both options: either using a motherboard adapter again or just using a 6-pin to 8-pin adapter for the graphics card. I don't know which option would be safer.
What would be the safest option to do, considering that during heavy gaming, the temperature of the graphics card exceeds 80°C and remains stable between 80°C and 85°C? At the same time, I don't want to risk damaging the motherboard or the graphics card if I use an adapter for either of them.
