So, my Antec Earthwatts 650 has been serving me for almost the past 10 years now. Iv been looking for a while now at different power supplies to replace it, but havent really found anything I like. Ontop of that, now Im kind of afraid to replace it as its lasted so long without issues. This thing has been through 3 builds, all run pretty much 24/7. The only time I turn my computer off is to clean, or if I know I am going to be away from the house for a few days. My current build I have had since 2012, and I already have to replace the case fans, although Im not sure how high quality those were to begin with. Should I replace my PSU if it isnt broken? I would like to get something newer and more power efficient but now Im afraid of the new one not lasting as long as this one.
