Hi, I just got myself a Super Famicom with no PSU. I would like to test this SFC before purchasing a proper PSU for it but unfortunately the only 'suitable' one for it only has 400 milliamps. I know the official one has 850 mA but I am not sure if it really needs that much. Any idea? Thanks! PS. Oops I think I posted in the wrong place!
I've got a UK and NTSC SNES, modified to take DC only, the UK one will power and work with a 650mA PSU, albeit with scrolling backgrounds looking dodgy, the NTSC will not. At 400mA, no, it won't work at all.
I think the SNES/Super Famicom wants 10 Volts, DC, at 850ma with Center Negative. Realistically you can use a Sega Genesis/MegaDrive MODEL 1 PSU which provides 9 Volts, DC, at 1.2amps with Center Negative. The 1 volt difference won't matter. But do not use a Model 2 or Sega 32X PSU, those are center positive and make damage your console if you tried using it.
For USA outlets, the SFC adapter is often safe enough to get by. In your case I'm not sure. DON'T try to use a PAL one! UK SNES expects AC which is totally wrong on SFC.
Some kind of bump, but thread is not too old though. Bought a Super Famicom without adapter. Tried Sega Genesis Model 1 one and got waves on the screen. Seems this one volt makes a lot of difference. These 3 in 1 adapters on eBay - will they work fine with it? Because how I see Super Famicom adapters are really overpriced (but maybe it's only on eBay?). Some Japanese shop asks 20$ for this - console itself costs me the same money. upd: I have an adapter for Fami Comfort (Japanese Famiclone), it will work for HVC-01 isn't it?
SFC has an protection diode on the power input. While you can't actually damage the system by connecting a PAL PSU on it, it won't run right because it will be powered with half-wave rectified current, which is not satisfactory even after smoothing (there's a 1000uf capacitor inside the SFC for that purpose). So you will get humm on the audio, wavy video and wrong colors, if the system even get to work. :shrug: Edit: Just mentioning, DO NOT TRY THAT on a FAMICOM as it has NO DIODES on it's input. You will have an fried 7805 voltage regulator in that case. >_<
I'm surprised the model 1 Sega Genesis adapter didn't work so well. Though I've never tried it personally. Radio Shack used to make 3rd party adapters that fit both US and JP SNES units.
