Need a spare MiSTer power supply for a standard setup? Then you're in the right place. These are the power supplies that come with the DE10-nano. They're rated for 2A at 5V.
If you intend to add an mt32-pi, usb powered hard drive, etc, upgrade to the premium 5A worldwide model. It was purpose built for MiSTer's needs and has been thoroughly tested by the MiSTer community.
