STPSU has undergone a makeover

STPSU, our premium replacement power supply for Atari 16/32 bit computers , has been upgraded to 2.1 revision.  So what’s new, you may ask? Beside minor layout changes and cutted slots to increase a level of protection for your precious Atari in case of (an unlikely) optocoupler failure, STPSU now features standard Molex connector. In result, you now can connect your upgrades and peripherials, such as floppy drive replacements, hard drives, memory upgrades, accelerators,… using widely available aftermarket cables. Output line filters were even more fine-tuned to ouput yet cleaner power.

All the rest remains the same – STPSU is still perfectly built, highly effective, performant, lightewight and stone cold running power supply, designed specifically for Atari ST and Falcon computers.

And yes, you still do not need anything else but a screwdriver to install it, that is true “plug&play” installation, style.
