    I just got a Sega Saturn "As-Is" today. Seems to have trouble powering on according to the person who I got it from. The Power port insert on the system looks... different. Can anyone here help me identify it? Thanks in advance.

    Looks like a standard launch model unit, those had a top-mounted power supply.

    Still looks like its AC. Any standard 2 prong plug should fit fine.

    I'm located in the US btw. Yeah, I just tested it. It turns on but it can't stay on. Light just keeps blinking on the unit.

    PSU issue perhaps...?

    Are you using a polarized 2-prong power cord or an unpolarized cord?

    I don't think thats going to make a difference, it should run directly into a bridge rectifier anyway

    Power issue is most likely dodgy connection on the low side of the PSU, clean the contacts and the pins, maybe tension them a bit (the dreamcast has this issue as well).

    also check the power switch, iirc it's mains voltage though !

    Isn't that the "only fits one way" US PlayStation cable? I believe it's sometimes referred to as C7 polarized. Bleugh!

    Technically, neither is polarized since it's AC ;) Never understood why that name was used.

    Because one side is tied to ground and the other provides power, it is a safety thing. In DC circuitry negative is ground.

    That's not true. It's AC. Neither side is tied to ground on the AC side of the PSU - it's a 2 pin plug. The neutral potential remains constant, close to ground, but it's not ground. Ground doesn't carry current - neutral does.

    It's not the same as a PS1 (though maybe a PS1 one would fit in it?). I'm almost certain I had a stereo system that used that same plug years ago.

    You need to be careful not to use a vanilla cord, as the plug has polarity!

    Do not stick in a generic cable!

    AC doesn't have polarity. As mentioned above. Generic cable will be fine.
