a load resistor on the 5V circuit makes the power supply think it’s hooked up to a motherboard. It’s all wrapped up in a neat slant-sided 3D-printed case that fits onto the ATX power supply ...

There are a variety of integrated circuits you’ll find running the show whose data sheets will often give you an entire ATX power supply schematic, but since their circuitries will often be very ...

SFX power supplies are built specifically for small-form-factor PC cases, and they come with a much higher power density.

Also, the main circuit uses Japanese electrolytic capacitors ... the Triton Rx series offers a solid option for those who need a reliable ATX 3.1 power supply.
