Small ATX PSU adapter, mainly for 12V loads, such as 3D printers.

RLoad need to be a couple of ~5W+, 20 ohm resistors. They’ll dissipate some heat. It’s needed for some ATX PSUs to be stable.
The LEDs will be powered on with 5v.
The power connectors are https://www.sparkfun.com/products/8432
The power on switch in the middle is something along the lines of http://www.amazon.com/dp/B00BT9FVTQ - The switching on portion needs to be between ground and PwrON. Basically, if using that switch, gnd=C and led-, pwron=NO (the center one), and 12v=led+.
Everything else is pretty standard and straightforward.
