Reviewers of the AMD Radeon RX 7600 reference version drew attention to the issue with its 8-pin power connector. It turned out that not all power cables with a 6 + 2 connection scheme that come with power supplies are suitable for this graphics card connector.
The stated incompatibility has only been found on some power cords. As mentioned earlier, due to the design of the card, some 6+2 pin connectors cannot be firmly plugged into the 8 pin connector on the graphics card. The reinforcing backplate of the graphics card at the power connector point protrudes strongly, preventing the cable connector from being stuck. The problem only occurs with some 6+2 cables and does not occur with monolithic 8-pin cables since they do not have additional notches in the part of the connector where the two additional pins are located.
According to TechPowerUp, this compatibility issue was found in 20% of the power cords in the test lab. According to Igor’s Lab, some custom cables, as well as those that come with the NVIDIA PCAT toolkit (a tool used to accurately measure the power consumption of graphics cards), may also not be compatible with the reference Radeon RX 7600’s power connector. In addition, there may be problems come with the power supply from Seasonic power supplies.
It should be noted that correct and firm contact with the power plug is important when installing the power cord. For the Radeon RX 7600 reference, a monolithic 8-pin cable or an extension cable with a monolithic connector design can be used to solve the problem. In extreme cases, you can dismantle the rear reinforcement plate of the graphics card. True, then you can lose the factory warranty.
On the one hand, the problem described seems minor and only affects some power cables. But it’s obvious that this is an oversight by AMD. She must understand that there are different types of power cables on the market and for this reason she could herself include the necessary extension cable in the packaging of the graphics card reference version. It is important to clarify that non-reference versions of the Radeon RX 7600 from AMD partners do not have this power cable compatibility issue.
It is also worth noting that, contrary to the original plan, the reference version of the Radeon RX 7600 will be available later. The novelty appeared on the company’s official website, but it is not yet possible to buy it.
