A heavy graphics card recently snapped the PCIe connector on a motherboard. The incident highlights how modern GPU designs can stress older or unbraced slots.
Heavy Gigabyte graphics card snaps motherboard connector after users skip mounting bracket.
The damaged hardware is a Gigabyte RTX 4090 GAMING model. This specific card weighs approximately 2kg and occupies nearly four expansion slots. Its physical dimensions create significant leverage against the motherboard socket.

PC1 repair shop reports this damage pattern frequently now. The shop notes that increasing size and weight in modern GPUs cause stress on unbraced PCIe connectors. Users often fail to use the included factory bracket or third-party support tools during installation.
The incident occurred in Japan according to the report. Gigabyte includes a mounting bracket with the card to reduce strain on the motherboard. The repair shop suggests that skipping this hardware leads directly to slot failure.
