Another Melted Connector: Sapphire NITRO+ RX 9070 XT Cases Now Reach Nine
The 12V-2×6 power connector saga has found a new recurring victim. A Reddit user has shared images of a Sapphire NITRO+ Radeon RX 9070 XT that arrived for service with a melted power connector and black-screen symptoms. The user reported using Sapphire’s included 3×8-pin to 16-pin adapter—the same blue-tipped cable that has appeared in nearly every public report involving this card.
Based on publicly available information, the Sapphire NITRO+ RX 9070 XT now appears to have at least nine documented cases of melted 12V-2×6 connectors. Reports have surfaced in October, November, December, and January, with the latest adding to the tally.
A Recurring Pattern
In every case, the user was using Sapphire’s bundled blue-tipped adapter rather than a native power supply cable. The pattern is consistent: the card itself shows connector damage, and the adapter is often found partially melted or with signs of overheating.
In a December interview, Sapphire’s Ed Crisler addressed the issue, stating that the company had seen three known cases at that stage. He attributed the failures to the adapter cable rather than the card’s connector or the power supply. The implication was that the adapter—not the GPU’s design—was the weak point. Since then, the number of public reports has tripled.
What to Do If You Own This Card
Sapphire has not issued a recall or a formal statement beyond the December comments. For owners of the NITRO+ RX 9070 XT, experts recommend:
- Avoiding the bundled 3×8-pin adapter if possible
- Using a native 12V-2×6 cable from a quality ATX 3.1 power supply
- Ensuring the connector is fully seated and checking it periodically for signs of loosening or discoloration
If you experience black screens, system crashes, or difficulty removing the power cable, stop using the card immediately and inspect the connector.

The Bigger Picture
The 12V-2×6 standard was meant to improve on the flawed 12VHPWR design, but melting reports continue across various GPU models from both NVIDIA and AMD. While Sapphire’s cases appear tied to the adapter rather than the card itself, the end result for the user is the same: a damaged GPU, a melted cable, and a warranty claim.
Until native PSU cables become the universal norm or the industry moves away from the 16-pin design, users of high-power cards should remain vigilant.
