It occurs to me that if you're replacing the voltage regulator ANYWAYS, you could just cut the VRM section out entirely and use a regulated 5v supply.


The guy who made the OP video used a modded PSOne supply that fed it around that.

Edit

Re: Ripple from the mods....

A cap on the voltage regs and a total system recap would fix all that.

Consolidating voltages...

Hmmm... Too bad that the only 5V PSU that I have at hand are old AT PSUs (bulky and with the wire mess), but the temptation to get rid of that original 12V brick is high.

Also: My Model 1 brick is rated at 12V 1A. Isn't that too high for a console not as demanding like the Genesis? How low could I go? (both in volts and in amps) From what I remember, nothing in the Model 1 requires 12V, but I wonder why Sega went for that voltage anyway...

I've never seen a Sega adaptor/console rated for 12V. O_o Maybe things are different down south?

The highest I've seen here is 10V (model 1602-1), which I use to power my AV Famicom. I'm not really sure whether it was intended to be used with a specific console/addon, or if it was just made to address some issue with the existing 9V 1602 adaptors.

Oh, yeah, please disregard that. I just found my power brick swimming into a pool of dust, and indeed the rating is 9V 1.2A (it's a 1602 model, no appendix), Guess that my brains swapped the amps with the volts somewhere.
