MSI has admitted that some of its MAG Z790 TOMAHAWK WIFI motherboards may be DOA due to a problem with its heatsink screw design, and with it comes the news that affected users will be able to get their hardware replaced, presumably free of charge. The admission comes a week after a repair channel shared a diagnostic of the board, calling it a “common” issue that it had seen over the past year.

MSI said:

  • “Regarding the MAG Z790 TOMAHAWK WIFI incident, we’ve discovered that a minority of units may encounter non-functional PCH potentially resulting in Dead on Arrival (DOA) of the motherboard product.”
  • “We have isolated the cause to a previously used chipset heatsink screw design and have taken proactive measures to address this issue.”
  • “A revised chipset heatsink screw design has been implemented into our production, and the known cases have been resolved.”
  • “We uphold high standards of responsibility and accountability, and want to assure affected customers can promptly receive product replacements. Please contact our local customer service center for assistance.”
