PlayStation 1 Power Supply Swapping

Howdy all,

Just wondering if anyone on here knows about compatibilty between SCPHs and their power supplies. I know on Sega Saturns there were three types that weren't cross compatible. Did the Sony systems have it a little more streamlined and have say... full compatibility across all models? I'd be most curious to hear!

Thanks in advance!

 

Hey, I'm writing this from memory so there could be small mistakes ;p

The very early PSX used an 8 Pin power supply. Every (fat) console from the PU-18 onwards works with a 5 Pin one.
Even though the power supplies were refined over the years, you can use any 5 Pin supply with any 5 Pin board.
They did change the capacity a little but the power supplies have enough reserves and I never noticed a problem.
Some people even adapted 5 Pin supplies for the older boards

Edit: Note that this is true for all regions. So you can swap a PAL and NTSC-J supply to adapt a console to your mains

Perfect, thanks! That's exactly the information I was after!

Ohhh no of course not...

Alright, you got me The PSU on my SCPH-1002 looks quite burnt around one part of the board. Everything in your one looks pristine! Plus the PCB looks a lot nicer than the PAL version (both are PU-8). Decisions, decisions! At least I know the SCPH-900X units can go out the window with no regrets!

Edit: Looks like the PU-22 and PU-23 machines all have Nichicon PSUs while the 100X ones have Matsushita. I'll be sticking with the PU-8 board for PSIO in that case. Might replace that burn / burning component on the PSU though - just to be safe!
