Review on 💡 Introducing the Electronics-Salon 24/20-pin ATX DC Power Supply Breakout Board Module: Simplify Your Electronics Setup! by Mark Powell

This little board will be incredibly useful for electronics and computer enthusiasts. exactly an extremely minor quibble: a pin is marked as "Not Connected". This pin refers to the -5V rail in the original ATX spec. It was dropped from the specification decades ago as motherboards largely phased out its use. As such, it is not used in any modern power supply. However, if you can find a very old power supply, you might still have that rail, and if you're running things like 5V op amps, you might need it. There ti is if you still have this rail in stock.
