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,

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?

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