We address a common issue that we've seen in the past year across many of these MAG Z790 TOMAHAWK WIFI motherboards. Clarification statement from MSI: "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." Follow us on Social Media: Instagram / https://www.instagram.com/joshirepair/ Feel free to contact us on: www.joshirepair.co.uk
