* CPC464+: computer and internal cassette player: 5V DC @ 2.4A
* CPC6128+: computer and internal disc drive: 5V DC @ 2.4A
'''All voltages MUST be smooth, the CPC does not have an internal regulator!'''
== Power connectors ==
* 5.5mm/2.5mm power line plug (providing the 5V for CPC and floppy)
[[File:cpc_power_plug_socket.jpg|800px600px]] NOTES:
* Outer diameter (A) is 5.5mm for all plugs and sockets, inner diameter (B) is 2.1mm for classic CPCs and 2.5mm for Plus
* short and long plugs exist, the ones used for the CPC and Plus are the short ones with approx. 9.5mm (C)
* === Pinouts for Power Sockets: === The +5V plugs and socketssocket on the back of the CPC / Plus is wired as CENTRE POSITIVE, i.e. the inner contact central pin of the plug is + 5V and the outer contact barrel is Negative (GND). <br> * for [[Image:Centrepositive.png|Image:centrepositive.png]] The +12V plugs and sockets, it's plug on the other way around, end of the outer contact is + and wire dangling out of the inner contact back of the CPC 6128 is GND* All voltages MUST be smoothwired CENTRE NEGATIVE, i.e. the CPC does not have an internal regulator!* If you want to use central pin of the computer without plug is Negative (GND) while the original monitor, then you will need a lead to connect to a television with a SCART input or a lead to connect to a VGA monitor that supports 15KHzouter barrel is +12V. <br> [[Image:Centrenegative.png|Image:centrenegative.png]]
