I've got a question about using an Xbox 360 PSU as Pi3 PSU.
Some background info why I want to use a 360 PSU to power a Pi3.
I'm planning on working on modifying a faulty Playstation 2 into a gaming station with a Pi3 and RetroPi.
I've got several Xbox 360 PSU's lying about here I've picked up for free.
The plan is to connect a DVD drive and a 500gb HDD to the Pi.
These require a bit more power than the Pi can supply.
The idea is to use the 5v-1A line, from the Xbox 360 PSU, to power the Pi and use the 12v line to power the HDD and DVD drive.
The won't have any other peripherals attached to it besides two USB gamepads via an USB hub,
I've got a step-down converter(12v to 5v) to supply the HDD, and DVD drive, with their own 5v that is separated from the 5v-1A line going to the Pi.
The 12v line has enough Amps to power the HDD and the DVD drive with enough left for the step-down converter.
Now my question would be would it be possible to power the Pi this way or would it be wiser to have a separate power supply, standard micro-usb PSU, for the Pi?
I hope I made some sense here with my background information.
Thank you for reading and any advice is welcome.
