Recently, we’ve heard horror stories of one user complaining that the new 16-pin 12VHPWR PCIe 5.0 connector on their GeForce RTX 4090 graphics card, had actually melted due to the intense power draw! How true is this story, we can’t fully verify.
This news has obviously affected AMD’s decision NOT to include the new 16-pin 12VHPWR PCIE5 Connector on their upcoming Radeon RX 7000 Series.

Taken from TPU … AMD just officially confirmed that its upcoming Radeon RX 7000 series next-generation graphics card will not use the 12+4 pin ATX 12VHPWR connector across the product stack. Scott Herkelman. SVP and GM of the AMD Radeon product group, confirmed on Twitter that the current RX 6000 series and future GPUs based on the RDNA3 graphics architecture, will not use this power connector. This would mean that even its add-in board (AIB) partners won’t find the connector as a qualified part by AMD to opt for. This would mean that Radeon RX 7000 series will stick with 8-pin PCIe power connectors on the card, each drawing up to 150 W of power. For some of the higher-end products with typical board power of over 375 W; this will mean >2 8-pin connectors. AMD is expected to debut RDNA3 on November 3, 2022.
