unebonnevie #1 Posted September 30, 2015 Hi, I just got a 4-port Atari 5200 off eBay. The seller bundled with a two-port system power supply rather than the proprietary one from Atari. I didn't know about this two-port and four-port versions of the Atari 5200 until today. Is there an alternative power supply solution (without acquiring specially made one by Atari) for the 4-port version of the Atari 5200? Thanks! Quote Share this post Link to post Share on other sites
Nutsy Doodleheimer #2 Posted September 30, 2015 Are you talking about the ac adapter? I have a 2 port and 4 port system. And have the power supply it came with the 2 port model. It works fine for both and will not do any damage. Quote Share this post Link to post Share on other sites

bohoki #5 Posted October 1, 2015 i think i use the 12v one for my 4 port unit so any power adapter 9-12 v 1amp minimum center tap it should be fine Quote Share this post Link to post Share on other sites
Nutsy Doodleheimer #6 Posted October 1, 2015 This is what the voltage and amps that come out of the 5200 power supply. 4-port: 9.3VDC, 1.95A 2-port: 11.5VDC, 1.95A 2 Quote Share this post Link to post Share on other sites
0078265317 #7 Posted October 2, 2015 So then 11.5v from 2 port will fry a 9.3v 4 port Quote Share this post Link to post Share on other sites
Nutsy Doodleheimer #8 Posted October 2, 2015 So then 11.5v from 2 port will fry a 9.3v 4 port No it won't. I have a 2 port and 4 port model 5200. I only have one ac adapter and it is from the 2 port model and I use it all the time for my 4 port console which is the one I regularly use. It won't fry anything. As long as it is a power supply that is DC with 9-12 volts. Quote Share this post Link to post Share on other sites
+-^CrossBow^- #9 Posted October 2, 2015 Retrogamer is right. The voltage regulator inside the 5200 is rated for at least a 12v input and will output to the needed voltages the 5200 requires. I too use a 11.5v supply with my 4 port units and never had a problem in well over 10 years of use! 1 Quote Share this post Link to post Share on other sites
unebonnevie #10 Posted October 3, 2015 Also, mostly to confirm. Is the Atari 5200 AC power adapter negative center or positive center? Thank you! Quote Share this post Link to post Share on other sites
