So on Nvidia's website, it says the GTX 1070 has a recommended PSU wattage of 600W. However, I only got a 550W PSU and I can't return it for a refund because I am a dummie. Here is my full build, and keep in mind I have already finished it except for the graphics card so there is essentially no going back.
