I have number of old systems with various 386, 486 and pentium 1 and 2 motherboards.
All have original power supplies but for peace of mind, i was thinking of replacing them with new ones.
However, using new modern atx psus is not ideal / wont work as they dont have -5V and I dont see ready made adapters that would have this built in (If I am wrong pls share a link where I can but some).
So, after much googling, I came across this :
New 300W PSU For Antec AT With Switch adjustable PC Power Spark Machine PP-300V Power P8P9 115/230V Power Supply

Cost is ok, I’d be happy to buy 10 of them and use in all my old systems but I thought I’ll check here with the experts before I go ahead.
Alternatively, am I reading it right that older ATX power supplies that had the 20pin power connector still carried negative 5V on them? And only since introduction of 24pin psus they dropped the -5v? If yes then should I try to find an atx psu thats 20pin ? Should be much easier than looking for AT psu. I can then use simple 20pin to AT power supply cable like this?
