Is all this stuff compatible together? I'm worried about some small detail or connector that I haven't considered. Will I need to buy any cords or should all of this stuff have what I need to put it together?
Rowewill sells one or two halfway decent PSUs. That is NOT one. I see that the final build went back to an Antec PSU, but I feel compelled to educate today 😛

This is a list that has been around for many years. It's a compilation of reviews from people that know about PSUs, and this is the most updated version.
