That new gadget
Has anyone here noticed that every new gadget that arrives not only has a power-supply-in-plug power supply (let's call it a PSU Plug) , but that a lot of these run quite hot, far hotter I am sure than they used to a few years ago ?
All those PSU Plugs are switch mode supplies now, due to some efficiency drive organised by a commitee somewhere, this means they are now the most likely thing to fail, in the past they were a simple transformer, four diodes and a capacitor, generally lasted the life of the device they were connected too as the manufacturers could not really find any ways of cutting corners to make them cheap.
Yesterday I found an old CPU cooler with fan, and epoxied it onto the PSU Plug feeding 9v to my router (wifi and four ethernet cables) and it now runs quite a bit cooler. Of course the fan required yet another PSU Plug, but that's another story.....
Bit convoluted posting but it's late, however does anyone out there also place a hand on their PSU Plugs and remark how warm they run ?
