From what I understand the only difference between the two, is that the first one is modular, and the second one isn't. I'm using an A320M-K mobo, a Ryzen 5 1400, 2x4GB HyperX Fury ram, my old Asus Formula HD5750 with 1 SSD, 1 HDD, but I plan on upgrading the GPU to a 4gig Sapphire Pulse Radeon RX 560. I currently have a Raidmax PSU, some people said that it isn't very good and stable, so that's why I'm changing.
