AI Summary: In 2025, a total of 88 cable melting cases were recorded. The majority of incidents involved Corsair cables, which accounted for 20 cases or about 23% of the total, followed by MSI with 13 cases (15%) and CableMod with 12 cases (14%). When looking at the GPUs affected without regard to brand, the RTX 4090 was the most frequently involved model, appearing in 23 cases, while the RTX 5090 followed with 15 cases, and the RX9070XT appeared in 5 cases. Other models such as the RTX 4080, RTX 5080, RX7900XTX, and several 30‑series GPUs also appeared multiple times, but the RTX 4090 clearly stood out as the most impacted across the year. Breaking down by connector type, about 73% of the cases (64 incidents) involved 12VHPWR connectors, while the remaining 27% (24 incidents) involved 8‑pin connectors, showing that 12VHPWR was significantly more prone to melting issues in 2025.
