I have a lot of old consoles, and I really mean A LOT. Most have the original power supplies but some don't and it's a mess either way. Some of the power supplies aren't even meant for 120v/60hz and adding a step-down or frequency converter only makes the mess worse.
What I want to do is make a bench power supply from an ATX PSU with modular connectors that can power anything I want it to power within reason. There are adapters on eBay and such that break it out to the different voltages ATX PSUs already output (3.3v, 5v 12v, and -12v), which means I would have to adapt for voltages like 7.2, 9, etc. Is there some DIY schematic for making selectable voltage with some voltage regulators? Are there any reliability concerns?
There are plenty of aftermarket switching power supplies for retro consoles, but that's just replacing one mess with another. I'm looking for a way to stow the original power supplies away while maintaining high-quality and stable power.
