We aren’t sure if [bm_00] needed a regular power supply to handle a graphics card or if the original power supply died, but either way, the HP small-form-factor box needed a new power supply.

[Frugha] decided to whip up a neat 3D-printed design for converting any ATX PSU into a usable bench unit ... a load resistor on the 5V circuit makes the power supply think it’s hooked up ...

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.
