Seasonic’s Wattage Calculator Adds Estimates for AMD Radeon RX 7000 Series

AMD and NVIDIA are gearing up for an explosive second half of the year. Both players are ready to unveil the next generation of desktop GPUs very soon with rumors about NVIDIA’s monstrous power requirements prevalent across town. AMD, on the other hand, has the golden opportunity to finally snatch the GPU crown it lost to NVIDIA all those years ago. Radeon RX 6000 series came close but AMD needs a champion to finish it off.

So far, we’ve gotten multiple leaks and rumors pertaining to both RTX 4000 (or 5000) series and Radeon RX 7000 series and today is no different. While this isn’t exactly a leak per se, it’s still an interesting little tidbit to look at and it gives us potentially a look into the real specs of AMD’s upcoming graphics card lineup.

Power supply manufacturer, Seasonic, who has a handy-dandy Wattage Calculator tool on its website has just added three Radeon RX 7000 series GPUs to its directory. This was first spotted by SkyJuice over on Twitter. While tools like these add placeholder names all the time, there is a chance the wattage estimates associated with these three Radeon RX 7000 series GPUs are genuine numbers provided by AMD to Seasonic.

PSU recommendations

Firstly, the three GPUs that were listed in the Wattage Calculator are: RX 7900 XT, RX 7800 XT, and RX 7700 XT. Assuming that the power requirement data the tool is using is correct, we can evaluate the real PSU requirements of these GPUs. In that case, the RX 7900 XT requires a 750W+ power supply on its own, and a 850W power supply with an 8-core Ryzen processor. Same is the case with the RX 7800 XT

The RX 7700 XT, on the other hand, requires 100W less so 650W+ for the GPU and a 750W power supply with an equivalent Ryzen system. These power measures are almost identical to current-gen requirements for Radeon RX 6000 series SKUs of the same model, which can be seen as a dead giveaway that these are, after all, just placeholders for the time being lifted straight from previous models.

Whether all that information is correct or not, what we can deduct from Seasonic’s Wattage Calculator is that Radeon RX 7000 series GPUs won’t use or come with the new PCIe Gen5 16-pin power connectors because the recommended power supplies for these GPUs don’t have that connector. Keep in mind that many reports have pointed towards RX 7000 series being in development well before the 16-pin power standard was finalized, which may the reason as to why AMD didn’t opt for it.


Soon enough, details surrounding AMD’s successor the RDNA 2 will start surfacing from official channels so we don’t have to speculate for long. If Seasonic’s data is somehow correct, it wouldn’t be too surprising since AMD engineers have been reported internally touting AMD’s efficiency, going as far as to say that RDNA 3 will “decimate” NVIDIA in terms of efficiency across the board.

With the recent leak that NVIDIA’s next-gen RTX 4060 GPU will use 100W more power than the current-gen RTX 3070, things aren’t looking too power-friendly for the Green Team. Perhaps, this is AMD’s ace up its sleave after all. Match NVIDIA’s performance and maybe even price, but defeat it in terms of power consumption. We’ll have to wait and see.
