This is a similar problem to a thread I saw, (http://) but includes problems that I think are related to the graphics card. I just recently replaces my Radeon Rx 460 with a 480 that I got from Best Buy, so it isn't likely the graphics card is broken. When I installed the gpu into my computer, I had to use the 6 pin to 8 pin converter that came with the gpu, because my psu didn't come with an 8 pin pcie. When I played a game, (I don't remember what game I was playing at the time) at a random time in the game, my computer would restart and boot up to a screen that said a power supply surge has been detected and that ASUS restarted my computer to prevent damage. This didn't happen with the old gpu I had, so I thought that the psu (which was a 450W Diablotek one at the time) wasn't giving enough power through the 6 pin pcie converter for the graphics card to function when it needed the power. I know that I have no idea how gpus work, and that my logic for this could be completley wrong, but thats what I thought the problem was. So, I bought a 500W EVGA psu with a 6+2 pin, which I thought was enough to power my gpu. I installed it earlier today, and I thought everything was good. Earlier today, I got a few games, one including COD: World at War, I played the opening sequence in the game, but after about a minute, my computer restarted again to bring up the message about the power supply. Is there something that is wrong that doesn't involve the gpu or psu? Or is the psu still not enough for the gpu? Or is it something else?
