The accucel6 is rated 12V 6A. So you would want a power supply to be rated at 6A or slightly higher.
Most Laptop power supply is rating +19V, so watch out for that.
Personally, I'm using a Currens 13A power supply CSM-815D.
Datasheet
Website if you're interested.
Don't ask me how much cos I totally forgotten.

Ok for anyone wishing to have a higher voltage out of a ATX psu, here is a simple tip.
For 15.3V you put +12V on the positive of your charger and +3.3V on the negative of your charger.
For 17V it is +12V and +5V, for 8.7V you can do +12V and -3.3V etc etc.
You can measure the voltages with your multimeter if unsure.
The only thing to watch out for is the max current each rail can output (3.3V normally can't output much current).
+12V and +5V can output the most current so just use them if you want a higher voltage.

If you put +12V on the positive of your charger and +5V on the negative of your charger, it should come out as 7V.
Instead you will get 15.3V when you put +12V on the positive of your charger and -3.3V on the negative of your charger.
Right? I havent touch electrics for 2 years, correct me if im wrong.
