The power supply works on my Asus X53, but unfortunately with undesirable side effects: In the loudspeakers during use was always to hear a slight crackle. Worse, however, that for several years so that our problems running powerline network was completely incapacitated - if the power supply was on, there was no connection to the Internet more. Once you ausstöpselte it again, the network was running again.
It was not only on an individual case, because due to a shipping problem I could try out two power supplies - both with the same problem.
Too bad, because I can completely recommend EIMM the seller - very obliging and comfortable rescission and great service!
