Within 2 years now and the 2nd power supply (the first was after 8 months exchanged under warranty) shortly after the warranty has expired even defective. The same problem, as reported here on several occasions. Evening still ok, electricity from dead in the morning. Since Trekstor obviously has a quality problem in terms of their power supplies, I will not let this company get a single additional penny of my hard earned coal. Sure, the disk maxi xu without power just does not work properly, but. Since I use the part of important back-ups, I'm going to now a hard drive of a reliable manufacturer and must establish necessity destroy the Trekstor plate physically. Just annoying when you consider what resources will be destroyed with it.
