  1. William Matthews

    I have two questions regarding the power supplies.

    1. The Falcon version of the PSU, will be okay with CT60 Falcon upgrade?

    2. You don’t happen to supply a PSU for the Atari Mega STe do you?

    Thanks in advance and kind regards,

      sorry, but its “no” to both your questions.

      Best regards, Pavel

    I saw no designated place for a review. So I will leave it here.

    I received the STPSU and it was very well packaged. I just finished installing it. It was very simple to work with and works perfectly. My original power supply died around 9 years ago. You have no idea how happy it makes me to see my STE boot up again!

    Thank you Centuriontech. I will certainly order from you again.

    Atari ST power supply says it is back ordered. How long does it take have one made then shipped?

    • administrator

      Currently, about a week.

  4. John

    How does the Atari ST power supply connect to a USA power cord?

    I purchased one of these about a year or so ago and it is truly fantastic. This PSU replacement is really the way you want to go. I love it so much I purchased another for another STfm unit in need of a PSU. I hope the backorder does not take too long 😉 Thank you Centuriontech!

    Easy to install. Works great!

    Bought one of these PSU to try to fix the noise my STE was sending through the audio output, lowering the quality of the footage for my youtube channel. It took more time unscrewing the chassis of the ST than the installation of the new PSU. Easy to install, works like a charm, problem fixed. Will buy it again if needed for my other STs.
    You really saved my YT channel, thanks and thanks also for the nice sweet gift, a pleasant surprise.
