my Orico hd-pw4101 power switch started to burn out after less than two yeasrs of use. The second switch burned out just a few weeks after the first one. Reason – short circuit at “Alpha & Omega” ‘s AO4801 power MOSFETs. This also leads power plugs at the device end to melt severely.
My PSU is gold standard 700W and it powers a system of less than 100W max power (fuly silent). Therefore I can attribute such burn only to the low quality of these mosfets. So, Watch out!
