AC/DC charger Adapter not working / is this a weak model ?

[Skaim]

Hi,
Just got a second hand stryx ROG gl702vmk and the adapter AC DC just stop working if i unplug it after some time charging, then replug it...
It re-works if i unplug/replug the power outlet after that (only thing that make it re-works) . So strange...
I was wondering if this is a known common failure on asus ACDC of these series ?  Or maybe these are weak or something, are they ?

Do you know if it worth trying to fix it ? Or at least if there are better alternatives that have same characteristics but more resilient ?
Or i'm maybe just unlucky ^^' and can just buy another second handled one ?

Thx for your advices 😉

Infos : 
AC/DC adapter : ADP-180MB F (180w 19.5v)
I've another ACDC : 120w 19.5v (Chicony) and laptop works fine with it, it charges itself after unplug/replugging adapter. But it has not enough power unfortunately for gaming usage.

My specs :
ASUS stryx ROG gl702vmk
GTX 1060 - i7 7700HQ - 16gb ram
NVME 3.0 500gb + SSD 500gb
Win 10 x64

Sounds like the internal breaker is tripping. Is the brick on fabric, rug, etc. or hard flat surface?

Hi, it's on hard flat surface

1) If you have or know someone with a wattage meter (test it).

2) Try another brick from somewhere. 

Else RMA it. 

When it shuts down is the brick Hot? That is a sign of tripping.

But does NOT tell you if it is the brick or the laptop. Creating the high draw.
