I'm in the middle of building my first gaming PC and need some advice on power supplies. There are so many options, and I'm not sure which one would be best for my setup. My budget is around $100, and I'll be running a mid-range GPU. Should I go for a 600W or 750W power supply? Is it worth spending extra for a fully modular option? Any brands or models you'd recommend for reliability? Thanks in advance for your help!
