I have two main questions:
1. Can you use ATX power supplies in industrial projects?
I see lots of DIY projects where they convert an old ATX PSU into a lab bench power supply or powering DIY projects. However, I have not seen any articles on using ATX power supplies in industrial projects that requires high power 12V and 5V rails. Are there any downsides to doing this? (PS: Industrial electronic projects such as embedded systems with various sensors)
2. Why a decent ATX power supply cost significantly lesser than a decent switch mode power supply of the same power rating?
A decent 500W ATX power supply from Cooler Master with 80+ efficiency can cost less than USD$50, whereas a 500W 12V MeanWell SMPS will cost at least double that. Wouldn't it be better to go with an ATX power supply then to power high power appliances such as motors?
