MSI Addresses Cracked Chipset Issues on Z790 Motherboard and Offers RMA Support for Affected Customers

After months of discussions on public forums, the issue was brought back into the spotlight by YouTuber Joshi Repair. As a result, the PC’s usual boot routine was disrupted, causing significant inconvenience for new consumers who were unaware of the faulty motherboard. However, following numerous complaints on platforms like Reddit, MSI has finally addressed the problem and released a statement, which reads as follows:

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.

“After further investigation, it was determined that the issue is due to a defective PCH, which falls under the “Dead on Arrival”policy. This means that MSI will take responsibility for all faulty units. Additionally, the company has acknowledged a flaw in the heatsink design of their Z790 Tomahawk motherboards and has already released a fix. This assures that future WeUs will not experience the same issue.”

If you have experienced PCH cracking, we recommend that you go through the RMA process outlined by MSI. As the problem has been identified as DOA, affected parties can expect to receive compensation. To begin the process, please visit MSI’s website here.

According to both MSI and Tom’s Hardware, sources have reported issues with the MSI Z790 motherboards due to a manufacturing error in the PCH chipset.
