Hello. I've recently purchased AMD Radeon RX 560 4GB graphics card. Ever since I installed it I've been experiencing various crashes during gaming. I did everything except replacing PSU (I checked every piece of hardware in my PC, everything runs fine but I still continued to experience crashes). AMD Raden RX 560 4GB graphics card requires 450 W PSU. I've got Antec EarthWatts EA-500D (500W Max.). Although my Power Supply Unit is 500W, I read on some website that it has got 80+ efficiency so it only uses 408 W, the rest is heat. Could this be causing crashes during gaming as my GPU requires 450W of power? Thank you in advance.
