NES Power Adaptor

    Anyone know what can I use as a replacement NES adaptor? It says AC 9V 1.3A on the bottom so can I just use any adaptor that matches that? Also will a SNES adaptor work, and does polarity matter?

    I use a universal one, as long as you have the polarity and wattage settings then your fine

    What's the polarity? I can't see it written on the console anywhere, I'm hoping I have something can use lying around. Otherwise I'll just buy that one, looks handy.

    Cheers lads

    any power supply between seven and twelve should do the job. The amp rating is the max current it can supply. It'll only draw what it needs. The polarity is what side of the supply is positive and which is zero volts. It usually is on the power supply it looks liked a circle with a dot in the middle.

    Snes psu will work,providing its the black box one,if you look at writing on the box itself it says use and (s)nes power supply

    The PSU for the SNES is identical to that of the NES, they're both 9V AC. I've seen some people use 9V DC PSUs instead but I personally wouldn't.

    Ac goes in one side, DC comes out the other. You'd know all about it if you put ac into a console :p

    No it really is AC, says it on the PSU itself. 230V AC is deadly but I'm sure 9V AC would be fairly insignificant.

    That's a new one on me :confused: I thought all transformers for electronics output DC.

    The above bothered me :rolleyes: so I checked it out. It seems the NES does indeed expect AC, but there's a little regulator straight inside the NES which takes that AC & converts it to 5v DC for use in the console. Why they didn't just do it all in the psu is strange though.

    That is odd. So I'd assume it wouldn't make any difference if DC was fed in? They could have put a rectifier in the PSU to do it.

    Exactly, it will accept DC also. Bizarre.
