AMD Radeon "RDNA 4" RX 9000 Series Will Feature Regular 6/8-Pin PCI Express Power Connectors

AMD will continue using traditional PCI Express power connectors for its upcoming Radeon RX 9000 series RDNA 4 graphics cards, according to recent information shared on the Chiphell forum. While there were some expectations that AMD would mimic NVIDIA's approach, which requires the newer 16-pin 12V-2×6 connector for its GeForce RTX 50 series, the latest information suggests a more traditional power approach. While AMD plans to release its next generation of graphics cards in the first quarter, most technical details remain unknown. The company's choice to stick with standard power connectors follows the pattern set by their recent Radeon RX 7900 GRE, which demonstrated that conventional PCI Express connectors can adequately handle power demands up to 375 W. The standard connectors eliminate the need for adapters, a feature AMD could highlight as an advantage. An earlier leak suggested that the Radeon RX 9070 XT can draw up to 330 W of power at peak load.

Intel reportedly cited similar reasons for using standard power connectors in their Arc "Battlemage" graphics cards, suggesting broader industry support for maintaining existing connection standards. NVIDIA's different approach reportedly requires all board partners to use the 12V-2×6 connector for the RTX 50 series, removing the option for traditional PCI Express power connectors. In contrast, AMD's decision gives its manufacturing partners more flexibility in their design choices, and MBA (Made by AMD) reference cards don't enforce the new 12V-2×6 power connector standard. Beyond the power connector details and general release timeframe pointing to CES, AMD has revealed little about the RDNA 4 architecture's capabilities. Only the reference card's physical appearance and naming scheme appear to be finalized, leaving questions about performance specifications unanswered, as early underwhelming performance leaks are somewhat unreliable until final drivers and final optimizations land.

Stop the bickering/insulting/drama.
Stick to the topic... warnings/bans/etc. to any who continues the BS.
You have been warned!

RuruProps to AMD, why fix something what isn't broken?


Wait, wut? How many revisions this new connector needs?
There have only been two.

somebadlemonadeSo the big issue was not enough testing was done on the new connector. And it had a lower than usual safety factor, anything less then 25% for power connections is genuinely bad.

Both sides are butt hurt about it. Nvidia made a new connector with same safety factor but a better designed interface between the connections to allow better contact.

TL:DR - It's partly marketing and partly reasonable to call out the issue with the new unproven connector with a lower than usual safety factor.
Are rtx50 going to use an unsafe connector ? Or are AMD just taking a shot at this connector while hoping this would play to their advantage ?

No and yes. In midrange+ there will be more users with old PSUs and those users prefer old cables, old connectors.

And yes. Absolutely, unless you're going for max.

You don't have to have a new psu for that, an adapter is included with every card. Franky,I find it easier with an adapter. I pług it into the card first, check if it has gone all the way in (giggity), then insert the card with the 12-pin already sitting neatly. Now all I have to do is connect the 8-pins to 8-pins, as usual. Don't see the drama. I suppose I don't really give a rat's ass what connector the card has, as long as the card itself is decent

Of course, and I use it like that too, but it's easier that way and more clean, without adapter. If I buy 5090 I will also buy new PSU, and happily get rid of this cable whip adapter, it's ugly in my case window. ;)
