Asus recalls flammable Z690 motherboards

Mounting a modern computer is a relatively simple process that nowadays requires neither a soldering iron nor good control of small passive components. This is done directly in the factory, but it is clear that there is no guarantee of a faultless product. Everything from power supplies and fan controls, to power connectors on graphics cards and PCI Express extensions from time to time offer explosions and fire hazards.

In recent days, Asus’ lavish “Alder Lake” motherboard ROG Maximus Z690 Hero has also been in the spotlight for the same hot reason, after reports of melting power supply. Youtube profiles like Jayztwocents and circuit board enjoy Buildzoid noticed this and the latter also pointed out a faulty capacitor as the probable cause. Via Facebook confirms Asus now that this is the case and preparing to recall affected motherboards.

To our valued Asus Customers, Asus is committed to producing the highest quality products and we take every incident report from our valued customers very seriously. We have recently received incident reports regarding the ROG Maximus Z690 Hero motherboard. In our ongoing investigation, we have preliminarily identified a potential reversed memory capacitor issue in the production process from one of the production lines that may cause debug error code 53, no post, or motherboard components damage. The issue potentially affects units manufactured in 2021 with the part number 90MB18E0-MVAAY0 and serial number starting with MA, MB, or MC.

As of December 28, 2021, there have been a few incidents reported in North America. Going forward, we are continuing our thorough inspection with our suppliers and customers to identify all possible affected ROG Maximus Z690 Hero motherboards in the market and will be working with relevant government agencies on a replacement program. Thank you so much to everyone for your patience and support while we are working through the replacement program. – Asus

The motherboards that are in the risk zone have a serial number that starts with MA, MB or MC, and article number 90MB18E0-MVAAY0. Both parts can be read on the packaging according to the picture Asus sends with its statement. The faulty capacitor is part of the power supply for the primary memory and can result in the fault code 53, that the system does not start, or in the worst case damaged components.

Asus continues to investigate whether more ROG Maximus Z690 Hero are affected by the problem, but customers who own such a motherboard should stop using it. Customers will be able to return and replace the motherboards in the near future, but the exact date for this remains to be seen. The future will also show whether motherboards sold outside North America have the same problem.
