Multiple users report MSI 12v-2×6 power connectors slowly backing out of both GPU and PSU ports, despite proper initial installation. A Reddit thread documents an MSI MPG A1000GS ATX 3.1 PSU with yellow-colored cable ends gradually working loose from a PNY RTX 5080 over two months, triggering system instability during gaming sessions.

This issue follows widespread NVIDIA RTX 5090 connector meltdown incidents that prompted manufacturers to add colored cable indicators as thermal warnings. Users claim they heard positive clicks when connecting cables, yet thermal cycling appears to cause plastic expansion and contraction, slowly loosening connections. The problem extends beyond a single case, with numerous commenters reporting similar experiences.

The creeping connectors expose the yellow warning ends designed to signal proper seating, but their gradual movement suggests a design flaw in MSI's cable retention mechanism. While no meltdowns have been reported yet, the instability during heavy loads raises serious concerns about long-term reliability. Affected users have been directed to request replacements through Amazon, though the volume of similar reports suggests this may be a widespread manufacturing issue requiring broader attention from MSI.
