No, you misunderstood me, I never mentioned anything about needing a multi-voltage PSU. I just want to replace old, giant brick power adapters for consoles like NES, Genesis/Sega CD, Famicom, PSOne, etc. with smaller and more efficient options.
I'd like to do this, too. I had been considering getting a 10-port USB charging hub to power 5V devices, like my OSSC, HDMI to VGA converter, and normally-USB powered stuff like the NES Classic, as well as for charging phones in the living room, of course. I figure it would be more efficient and would save some space by switching from a battery of wall warts to one power lump that I could set off to the side or behind my stuff. Unfortunately, I read recently (On these forums, I think, but I don't recall where) that USB chargers (mainly the cheap, unbranded ones) don't always provide clean power, which would negatively affect video processors.
Thinking about it more, I think it would be nice to have something along the lines of a modular ATX power supply, or a power strip, that would be able to supply clean 3.3V, 5V, 9V, and/or 12V DC, depending on the need, to multiple devices. It could use keyed 2x3 Molex connectors and differently-wired/ended cables for each system. Have an NES, SNES, or VB? Your cable is wired for 9V and has a barrel plug. N64? 3.3V and 12V into a compatible 3x2 connector. OSSC? 5V and a barrel plug. DreamPSU? 12V and a barrel plug. It would be possible to create cables with MicroUSB on the end, but it'd be simpler to include a bank of 2.4a or 3a USB ports compatible with USB-PD and/or QC so you can use your own cables.
Since it's not like barrel plugs are keyed for different voltages, I would want cables to be clearly labeled on the console/device end to reduce mishaps; perhaps a nice, big tag with "12V" or "5V", or, for console-specific cables, plop a nice, big "NES/SNES/VB" or whatever on there, in addition to the voltage.
I'm aware of some bench PSUs that are set up like this, with a bank of barrel jacks, but I recall from the
Guitar Pedal PSU thread that these aren't all that good for game consoles.
