– Aryeh Leib Taurog Commented Jun four, 2015 at 9:37 PSUs generally possibly perform or Really don't; I have never ever noticed or heard about a single failing in a method wherever it outputs the wrong voltage. It will also most likely be the very เครื่องสํารองไฟ etech first thing to fail. I've hardly ever witnessed a case where by a surge fried a bunch of interior components but still left the PSU unscathed.
Until you happen to be in a place with continual surges, You would not very likely see many equipment and parts failing at distinct occasions. More possible clarification: the restore shop is working with reduced top quality, refurbished parts rather then new areas, and/or performing a lousy work with thermal paste. But that also would not clarify the other gadgets.
