A bit off topic, but I am not a fan of switching power supplies. Yes they are efficient but I don't like the noise they generate and being a component level tech, I found them very difficult to troubleshoot. But,as I look back, I realize my skills are no longer needed as techs now a days just replace the whole thing. The replacements we got in our company didn't even know how to use a analog meter. Maybe it's just me getting old or manufactures skimping on design for cost purposes. We had a high failure rate on equipment using switching power supplies. But, hopefully things will continue to improve as these things are the future.
