I am building my first PC gaming budget build and I have no idea how many watts my PSU is going to need. I am expecting to do intense games such as battlefield 1 when it comes out and the last thing I want is my components busting because there was not enough power. However I also don't want to waste money on too many watts. Originally I had aimed around 520 but after sprucing things up I am nervous I might need more. Below is the link to my build. Any help would be extremely appreciated.
