ASRock’s Flagship Z690 Aqua OC Motherboard Joins The Thousand-Dollar Club, Costs $1399 US

in mid 2018(June) both finally were affected by capacitor plague. Inferior Capacitors built in which will die or get ill before promised life-end. at around 5000hrs instead of 10000. I examined these 2004 and later MOBOs(have multiple copies) really to the ground. Only found out what was the reason a bit later. after 3 weeks i could reactivate both pcs. both were working outside cases. there is a looong Mono-thread by me. Defective PSU or something like that. to follow and understand it will need a lot of time and nerves.
I am now on two ultrabooks by Acer. windows 10. There were other problems which could also be read here. or in german and english Acer-forum.
I will not go back to desktop. maybe reactivate and upgrade an Asus Z87C(older i7) 16/256/2.
Hope a new capacitor plague will not come back. manufacturers have certainly learnt their lessons. NB : there is a Capacitor Plague-Forum.
There is a company or multiples? offering a laptop-system which is easily upgradable.
