The ATX2AT PC Saver

In 2019 Sam Demeulemeester (he’s actually Belgian, although I say French in the video) did a Kickstarter for the ATX2AT smart adapter. It allows you to safely attach a modern ATX PSU to a retro mainboard with AT connectors. That is your precious 286, 386 or higher will now be safe from overcurrents due to wrongly inserted CPUs, broken expansion cards, failing tantalum capacitors or rogue power supplies. It might not save the world, but it will probably save your valuable retro PC. I already lost two precious mainboards and am glad to have finally received the ATX2AT smart adapter!
