NVIDIA has made a statement on the RTX 4090’s 12VHPWR melting power connectors. The chipmaker claims it’s actively monitoring the reports and is aware of 50 cases. Its findings indicate that a common reason behind these thermal accidents lies within human error: loose power connector plugs. This aligns with what JonnyGuru, Corsair’s power supply expert, said a few days back.
It’s worth noting that GamersNexus recently reported that a manufacturing flaw might also be causing these issues (or at least worsening them). For likely legal reasons, NVIDIA hasn’t admitted any defect of this sort. Its only recommendation is to plug the power dongle into the graphics card first to ensure it’s firmly and evenly plugged in before plugging it into the motherboard.
Our findings suggest that a common issue is that connectors are not fully plugged into the graphics card. To help ensure the connector is secure, we recommend plugging the power dongle into the graphics card first to ensure it’s firmly and evenly plugged in before plugging it into the motherboard.
We are investigating additional ways to ensure the connector is secure before powering on the graphics card.
NVIDIA and our partners are committed to supporting our customers and ensuring an expedited RMA process, regardless of the cable or card used.NVIDIA
