Sega Saturn Switching PSU

I'd be interested to bookmark anything you find. Plan on having a similar problem one day soon.

You can try mod your PSU with mini-ITX power supply like that guy:

But it probably woud cost more than gutting old and busted Saturn.

There's also this mod anon.

Any form that can be installed, yes. Specifically designed as a drop in replacement, no.

That's a clusterfuck but in fairness he admits that. The concept is fine though. Pico PSUs are overpriced because they're meme toys. Still cheaper than gutting another console. You could build your own for a couple bucks. You could even hack one together out of a few modules if you can't into PCBs.

what do you think the PSU is doing in the first place.

anyhow, it would be pretty simple to use a scope to figure out what sort of signal you need and build your own PSU

I disagree. It's a very clean looking mod, assuming you have the time and patience to desolder the existing PCB and re-purpose it.

It would be cool if someone designed a PCB in eagle or openCAD to be a drop-in replacement for the dreamcast/saturn PSU capable of accepting multiple AC voltages, and used off the shelf components.

You could possible get the guy to make a Saturn version, though it could be problematic since Saturns use something like 6 different PSU pinouts internally.

Designing that PCB is easy enough but there's not much point. Assembly would be a pain in the ass and people who need the device couldn't do it. So you'd end up getting it done by a prototyping place and the price would be silly for the 2 people who actually did it.

Going with a DC-DC solution has a lot of advantages. The "expensive", failure prone, heat generating, certification requiring, high voltage part can be bought off the shelf. It sits outside the console. It's easily replaced. It can be used for multiple devices.

You can deal with that using jumpers or a harness. I'd go with a harness as kiddos will invariably fuck up jumpers. What your kickstarter lad should have done is make a 12/9/5/3.3 PSU and designed the board so it could fit securely in both consoles. Then use a different harness depending on the pinout the console needs. Or he could have just used a $15 pico and and built a ATX-DC harness for a couple bucks. That's what I did and I didn't even need a kickstarter. For an extra buck I could add a module to give me 9v as well and rewire the harness for any given saturn.
