In the course of our testing of the reference-design AMD Radeon RX 7600 graphics card, we noticed a flaw in the physical design that could impede certain kinds of 6+2 pin PCIe power cables, causing improper power connector contact, posing a potential fire hazard, theoretically. The flaw centers on the design of the card's backplate. The cutout near the power connector is designed such that certain kinds of 6+2 pin PCIe power connectors don't properly insert. Most if not all power supply units (PSUs) have their 150 W, 8-pin PCIe power connectors designed to be 6+2 pin, where you can split two of their pins away, turning them into 6-pin PCIe. While some PSU brands use a passive hook-type tail-end bridge that ensures the 2-pin portion inserts along with the 6-pin portion, some brands use more elaborate stubs. The AMD RX 7600 reference backplate design impedes these kinds of connectors.

We reached out to AMD with our findings before the May 24 review NDA, and the company got back to us with a statement:

We are very pleased with the volume of Radeon RX 7600 cards available globally from our AIB partners. We expect RX 7600 reference design cards to be available over the coming weeks with a design that accommodates all power supply cables.
