Hello and sorry for my bad english. I have on my possesion an HD 7870 Ghz edition ! The problem i face is that when i am on a demanding game such as Call of duty Ghsosts / Battlefield 4 my pc starts to smell like burning plastic. On games like League of Legends i dont face any problem at all. I try to monitor the temperatures of my GPU and i get 75-80 on max load ! My PSU is a hantol 550W which is a 20 euro psu. Do you thing that the burning smell is could be from the crappy psu i have? I would like to add that i have 3 fans total in the case and the airflow is quite good so far.
