The inside of a 650-watt High Power ATX12VO power supply is pretty empty, thanks to the lack of circuits for 3.3-volt and 5-volt rails. The cabling is also fairly simple.

The ATX supply [C] used could supply 25 amps on the 12 volt rail, more than enough for a simple RepRap. There was only one problem: the supply would randomly shut itself off, ruining the print.

It’s not entirely clear why [Advanced Tinkering] needs a 50,000-volt power supply, but given the amount of work he put into this one, we’re going to guess it will be something interesti… ...

About the Solar Power source. During day time, the security system gets 12 volt power supply from the battery or the Solar Panel. If the amount of power from the solar panel is not sufficient, battery ...

(It’s also called 12-volt high power.) These connectors are capable of sending up to 600 watts on a single line (though not every power supply can push that much).
