traindriver69 Posted May 28, 2020 Share Posted May 28, 2020 Hi all I have a Atari 400 computer but no power supply I see it requires 9vac 3.4amps I have looked in my bag of old power supplies and found a multi adaptor it says 9vac 4 amps would this be ok but I am not sure about it being a switch mode power supply if that will make a difference any help please. Many Thanks in advance Quote Link to comment Share on other sites More sharing options...
xrbrevin Posted May 28, 2020 Share Posted May 28, 2020 the 400 requires AC input, the one you found is DC that symbol with the solid line and 3 dotted lines underneath means DC (a wavy line would denote AC) 1 Quote Link to comment Share on other sites More sharing options...

xrbrevin Posted May 28, 2020 Share Posted May 28, 2020 (edited) european spec NES adapters work if you can find one or from amazon you can get guitar effects pedal power supplies that are "9VAC" or from ebay: https://www.ebay.co.uk/itm/173560426585 Edited May 28, 2020 by xrbrevin found ebay item Quote Link to comment Share on other sites More sharing options...
