Modern switching replacement power supply for the ZX Spectrum +2A/+2B/+3.

This is a replacement for a defective or unserviced original ZX Spectrum +2A/+2B/+3 PSU.
Using an unserviced original power supply for these models, will very likely sooner or later cause damage to your ZX Spectrum and add-ons (it’s no problem using a serviced original PSU).
During the last years we’ve had several customers with defects caused by an unserviced power supply for these ZX Spectrum models.

Main features:

  • ON/OFF switch – no need to unplug the PSU anymore!
  • Comes with top grade 12V 2A wall PSU, with UK mains adapter if you live in the UK
  • Best looking replacement PSU ever – high quality vinyl label!
  • A-brand, top quality, no noise.


  • ZX Spectrum power plug type of this PSU version: plastic (metal plug version also available)
  • Input: 100-240V 50/60Hz
  • Ouput: 5V+12V 1-2A (no -12V, see note underneath)
  • Cable length: about 1 m from wall to PSU unit, 20cm from PSU unit to ZX Spectrum

Supported ZX Spectrum models:

  • ZX Spectrum +2A/+2B  (black ZX Spectrum +2 model, not the grey one)
  • ZX Spectrum +3

NB: For the ZX Spectrum 16/48K / 128K+ / grey +2 and other ZX Spectrum models and clones, you need another PSU also available in this webshop!
NB: If you’re using the RS232 or MIDI port of a ZX Spectrum +2A/+2B/+3, you need a power supply that also supplies -12V which this one does not! We’re working on a version that also supplies -12V.

  1. This is an awesome product, been waiting patiently for it to become available. As far as I know its the only replacement psu for +3.

    Had a failing psu, 12v side not functioning and therefore the floppy disk wasn’t spinning. This has fixed this of course, with the added bonu sof being lightweight and power button!

    Only minor thing for me was the size of the power adapter, the unit itself is tiny but the plug is huge. Cheers Ben for making this available at last.
