howerton Posted July 2, 2023 Share Posted July 2, 2023 I am looking in to buying a European Atari ST. I see they take a standard PC power cable. My question is if I put a US power cable in the power slot and run my European ST, will the ST be good power wise? I.E. no overheating, damage to the ST or electrical fires?

No. They are not universal power supplies and are generally different. Undervolting a 240VAC PSU with 120VAC would cause no damage, it just wouldn't supply the load. Some European ST power supplies may have a strap to switch between the two voltages 240/120V but it would be a gamble. You could ask to see the type of PSU, if it has two input capacitors, it may have a 120V strap. For instance an Astec ASP34 will have a strap W1 to choose between the two voltages. Beware the DSP 508A though as it has 2 input capacitors but no strap. Edited July 2, 2023 by TZJB Quote Link to comment Share on other sites More sharing options...
351cougar Posted July 4, 2023 Share Posted July 4, 2023 the original supplies were region specific. ie 240/250V - 50 hZ or 120V 60 hZ. The cord was the same, as it was a nema standard (dont remember the version). It will supply to the PS whatever the wall does. If the PS hasnt been replaced with a modern universal unit (~85-260V), it will be expecting ~240V (you stated Europe original) . Look thru the forums for good PS replacements.

ijor Posted July 4, 2023 Share Posted July 4, 2023 Actually, it might work. I had an ST with a 220V/240V PSU running from 110V just fine. I understand it is not very healthy for the PSU, but it is not fatal like the other way around (a 110V PSU connected to 220V). 1 Quote Link to comment Share on other sites More sharing options...

Probably less heat generated so a longer life. I don't suppose you know what make of PSU? Quote Link to comment Share on other sites More sharing options...
