Thx for measuring.
So... 4 me it looks like that a PS4-USB3-port can easily power this, so nobody needs to worry about his PS4.

I got my RPi 3 in the mail today. I was able to load Raspbian on an sd and update it through the RPi, load GIMX, and create the GUI run automation file in a little under an hour. I didn't have much time to actually use the setup, but it starts up and is ready to go in like 10 seconds now. It doesn't even go though a full wheel calibration. I'm not sure if thats bad or not. I only had time to navigate through menus on the PS4, but I've been able to power and communicate with the RPi 3 using 1 usb port on the PS4. I had the USB meter connected and It spiked up to 900+ma a couple of times, but I also haven't disabled wifi and bluetooth yet. I'll get in a race or two when I get a chance and report back.
