Radeon RX 7600 public graphics card is not compatible with some 6+2 pin PCIe power cables
Recently, AMD launched the latest generation Radeon RX 7600 for the mainstream market, based on the RDNA 3 architecture. It is equipped with the Navi 33 XL GPU, crafted using the 6nm manufacturing process and PCIe 4.0 x8 interface, and boasts an Infinity Cache of 32MB. Comprising 32 compute units (CUs) and 2048 stream processors, it is furnished with 8GB of GDDR6 video memory, with a memory bus width of 128-bit and a memory speed of 18Gbps.
TechPowerup has reported a potential physical design flaw in the Radeon RX 7600 reference graphics card. This defect could cause compatibility issues with some 6+2Pin power cables, leading to poor contact and theoretically posing a fire hazard. The flaw primarily stems from inadequate space on the backplate, preventing certain enlarged 6+2Pin power cables with securing clasps from being fully inserted.
TechPowerup noted that about 20% of the 6+2Pin power cables they tested presented this problem. Prior to the lifting of the Radeon RX 7600 review embargo, TechPowerup communicated this issue to the officials. AMD, through TechPowerup, issued a statement addressing the problem:
“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.”
Various manufacturers such as Sapphire, PowerColor, XFX, ASRock, ASUS, Gigabyte, MSI, and Biostar have announced the launch of Radeon RX 7600 graphics cards, gradually entering the market. Based on AMD’s statement, it can be interpreted as to why none of these brands launched a product with a reference design, possibly preventing the distribution of this batch of graphics cards in advance.
AMD’s term ‘in the coming weeks’ does not specify a definite timeframe. During this period, certain modifications should be made to the graphics card, mainly necessitating the customization of a new backplate to resolve the compatibility issue with the 6+2Pin power cables on the existing Radeon RX 7600 reference graphics cards.
