Bought this base build off of a manufacturer but the GPU was terrible. I decided to upgrade the 63w with a 250w and after about 20 minutes of testing on FarCry 3 there was a small bang and the whole system cut off accompanied by a smell of burning wood. Haven't yet plugged it back into the mains as I am cautious of the possibility of it damaging the rest of the build. Anyway, I have bought myself an Corsair CX600 assuming my old PSU is bust. Do you think I should attempt running the IGPU in order to check if the components are working properly or not take the risk? Thanks forum.
