Hi I'm trying to build my first pc and I plan on streaming with it. I have decided on most of my parts but can't seem to decide on a power supply,graphics card and hdd memory.The power supply because I don't know what kind of wattage my build would require and online calculators don't seem accurate to me. The hdd because I don't know what brand is the most reliable and the graphics card because I'm not that knowledgeable. I have a lot of questions and I'll just post my build till now here.
