I have a race and flight simulator with a lot of controllers that need to be plugged into USB ports. The steering wheel, pedals, keypad, TH8A switch, as well as the HOTAS joystick, steering wheel pedals, MFD panels, and headset all require connectors, but the PS4 only has two. One of the PS4 ports has my external hard drive connected, so I connected that USB 3.0 expansion port to another on the PS4. Wall outlet power means all of my accessories can be plugged into the USB port and are ready to go. Some even serve as charging ports. Great addition to my gaming system.
