GET THE NEW PSU AS YOUR ZX SPECTRUM IS WORTH IT.

ZX Spectrum +2 PSU. ZX Spectrum +3 PSU.

ZX Spectrum +2A running new Spectrum PSU+ by Electroware

The ZX Spectrum +2A, +2B computers were originally equipped with heavy (2kg in weight), transformer based PSU. Spectrum +3 was equipped with stronger, quite reliable, switching mode PSU handling bigger loads because of integrated 3"floppy drive. The best of the original PSUs were offering 5VDC@2A, 12VDC@0.7A & -12VDC@0.05A. All of these PSUs have same problem nowadays: all are nearly 40 years old and not longer reliable because of capacitors degradation. Old power supply, if still working, can ba a source of killing over voltage spikes that will burn your chips.

If your PSU is not longer working or you are not sure about it's condition - it's time to get a solid, superior quality replacement. It's 50W (55W peak) of total combined output power is far more than two times stronger than best model of original Sinclair ZX Spectrum +2, +3 PSU and it's two times smaller in dimensions and weight (0.4KG) to save your desk's space. 

I believe your ZX Spectrum is using many enchantments nowadays as fans and users are creating wonderful hardware stuff like FDD emulators (using SD Card), video output enhancers and VGA/HDMI adapters, WiFi serial modems, memory upgrades etc... all to enjoy.  But remember that all of these gadgets are stressing the PSU and original one become even more dangerous when working overloaded.

Please notice that most of cheap PSU replacements for ZX Spectrum +2/+3 computers are missing the -12VDC voltage (used for serial port) basing on the fact that most users is never using it so will never notice. Some of other popular replacements are stuffed with overrated gadgets but are missing the main on/off switch to make te construction cheaper! Our philosophy is opposite: reliable PSU replacement needs to supply all three voltages (as per original specification) but offering more power on each line. The reliable, mechanical On/Off rocker switch is a must for computer health, overall safety and energy saving.
