Another Sapphire RX 9070 XT Nitro+ graphics card has fallen victim to a burnt 16-pin GPU power connector—raising concerns across the PC hardware community as similar incidents continue to mount in 2025.

Reddit user u/divinethreshold reported their Nitro+ card suffering random black screen crashes. Upon inspection, they discovered scorch marks on the top row of the 16-pin (12VHPWR / 12V-2×6) connector, a now-common failure point in several high-end and midrange GPUs.

This marks the third known case involving Sapphire’s Nitro+ RX 9070 XT, joining similar reports affecting Nvidia’s RTX 5090 and RTX 5080. All cases share one technical flaw: improper contact between the connector’s bottom-row pins and the GPU socket, leading to electrical overload on the top row.

Despite the Nitro+’s 304W TGP, the strain proves too much when paired with bundled 3x 8-pin to 16-pin adapters, especially in builds using non-ATX 3.0 power supplies like the Corsair AX1200i. The GPU’s internal connector layout forces L-shaped bends, compounding the problem.

Some users report similar damage even with native ATX 3.1 power supplies, suggesting that the issue lies less in user error and more in connector design limitations. Products like Segotep’s Titanload cables, with reinforced pins and heat-resistant insulation, are gaining traction as safer alternatives.

Experts recommend:

• Using native 16-pin connectors whenever possible
• Avoiding tight cable bends or hidden shroud placements
• Inspecting GPU cables for early signs of heat damage

The affected user has initiated an RMA with Sapphire, but the broader question remains: should this connector standard be reevaluated across the industry?

As more RDNA 4 and GeForce RTX Series cards adopt the 16-pin standard, consumers are urged to prioritize clean installation and trusted cable brands.
