Plenty of slots for all of your components and supports 2x6 pin 600w graphics card supplies and is PCIE5 compatible. Both very important for modern builds The included cables are high quality and look great. They're long enough to wire up a full size case with plenty to spare. The wires are fabric braided and are combed from the factory. They also come in a nice fabric pouch which helps you neatly store any spares after your build.
