Sega Saturn Power Supply Swapping

SS - 0801
Sega Saturns tend to have one of three power supplies. The very long (above), aka “Type B”…

SS - 0802
And the slightly shorter known as “Type C”.

You can mix and match between like types, 110V to 220V and visa versa but they have to be a physical match for fitting. You also lose out on the 9V/12V rail on PAL consoles, I believe that’s used for SCART RGB switching or something along those lines. Don’t quote me on that though. Composite or bust!

There’s also the “Type A” for the Model 1 VA0 Saturns where the PSU is attached to the upper casing rather than the bottom casing. Summed up here by Zyrobs:

Type A is only used in VA0 motherboards, it is held onto the top of the case. Pinouts are gnd, gnd, 3.3v, 5v, (not connected), 9v.

Type B is used in VA1 to 5, it is the “longer” power supply and is always 5 pin. Pinouts being gnd, gnd, 3.3v, 5v, 9v.

Type C is used from VA6 to VA15, it is the “shorter” power supply. NTSC machines have 4 pins: gnd, gnd, 5v, 5v. PAL machines use 5 pins: gnd, gnd, 5v, 5v, 9/12v.
