Seasonic's official Power Supply wattage calculator page has been updated to support the AMD Radeon RX 7000 series of GPUs. Twitter user SkyJuice spotted the 'error.' According to Seasonic's handy web tool, AMD's upcoming RDNA 3 graphics cards will consume similar amounts of power as their predecessors.
If you head on over to the Seasonic wattage calculator page now, you'll be greeted with a simple but functional page. You can select components from a series of drop-down lists and then press 'calculate' to get a page full of Seasonic PSU recommendations.
According to the tool, a mid-range modern Core i5 system packing an AMD Radeon RX 6700 XT requires at least a 650W PSU. Swapping the GPU out to the unannounced RX 7700 XT and recalculating results in the same minimum recommendation — a 650W PSU. The database Seasonic uses also appears to hold wattage values for the Radeon RX 7800 XT and the RX 7900 XT. Below you will see the figures we got from plugging in the unannounced RX 7000 series cards and their current-gen counterparts.

The above PC system was configured in Seasonic's calculator with an Intel Core i5-12400, a GPU as above, twin SSDs, twin system fans, and no HDDs. *Please note that Seasonic recommends a 750W PSU for the system configured with an RTX 3070, but Nvidia says it is OK with a 650W PSU. Additionally, our article about GeForce RTX 4060 power requirement rumors is based on a source saying the upcoming RTX 4060 may consume more power than the current RX 3070 graphics card.
The above results are interesting to see with users concerned about the ballooning power requirements of discrete GPUs for PCs. There have been a number of rumors of very high power requirements for next-gen PC GPUs. If this AMD information is accurate it could be a good sign for fans of the red team as they await some official RNDA 3 architecture and product announcements.
Seasonic's PSU calculator also features the Radeon RX 6700 non-XT, which was listed by Sapphire last week but isn't yet an official product on AMD's website.
Readers should add a pinch of salt to the above data found on the Seasonic website. It is possible but unlikely that these are input errors. However, they could just be using placeholder figures rather than basing their calculations on data on the next-gen GPUs supplied by AMD.
