Help identify Saturn power port

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.

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.

 

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