Unannounced Nvidia RTX 50 Super GPUs appear in Seasonic PSU calculator — unreleased graphics cards shown with 10-17% higher TGP over original models

The GeForce RTX 50-series desktop graphics lineup has remained unchanged for just over a year now (since the introduction of the RTX 5050), and none of the conversations we've had at major trade shows suggests that a mid-cycle Super refresh will occur any time soon. But there are still signs that such an update could still happen at some point, and the latest sign comes from Seasonic, which has listed an RTX 5080 Super, an RTX 5070 Ti Super, and RTX 5070 Ti Super in its PSU wattage calculator.

You can click through the calculator and assemble a hypothetical system with these unannounced products inside.

To be useful, this calculator also provides board power numbers for these as-yet-unreleased cards, and that gives us another bit of juicy info. Given that no official specifications for these GPUs exist, it's impossible to say whether these figures are accurate. But it does allow us to speculate a bit on how they might stack up to existing products.

Seasonic gives this purported RTX 5080 Super a board power of 415W in its calculator, or 15% higher than the existing RTX 5080's 360W envelope. That makes sense, because the RTX 5080's GB203 GPU is already fully enabled, so any Super version of that card would have to lean on higher power limits and more aggressive clock speeds to see any baseline performance benefit.

That figure could also partially account for slightly higher power usage from 8 GB more GDDR7 memory on such a card. Past RTX 50 Super-series rumors have suggested that Nvidia will boost VRAM capacity on those products by moving to higher-density GDDR7 modules with 3GB of capacity each. GDDR7's power consumption as part of the overall board picture is relatively small, but more of it will still matter.

If Seasonic's figures are accurate, we should also expect a similarly sized TGP increase out of the RTX 5070 Ti Super, whose 350W rating is 17% higher than that of the RTX 5070 Ti. The RTX 5070 Super, meanwhile, gets only a 10% TGP bump over the RTX 5070, from 250W to 275W. Both of these cards rely on GPUs that are slightly cut down from their full available resources, so it's possible that Nvidia could boost their performance through a balance of enabling more Streaming Multiprocessors (SMs) in addition to boosting clocks through higher power envelopes.

Beware of extrapolating performance improvements directly from these percentages, though. Our own testing has shown that any real-world performance benefits from these power limit increases are likely to be smaller than those figures would suggest.

As our review of the MSI RTX 5090 Lightning Z showed, the largest performance boosts from higher power limits are likely to be concentrated in ray-traced and path-traced games, whose computational intensity is significantly higher than pure raster titles and is more likely to run the GPU into its power limits.

In any event, we shouldn't expect to see these products any time soon. Nvidia has instead been focused on getting more out of existing Blackwell silicon with software improvements such as DLSS 4.5 upscaling and Multi-Frame Generation multipliers up to 6X.

These technologies enable higher output frame rates and image quality with lower input resolution than past DLSS technologies, and the boost to both performance and image quality from those technologies in tandem has certainly made existing Blackwell products more appealing than they were at launch.

But as monitor refresh rates continue to climb thanks to ongoing improvements to OLED and LCD panels, and next-generation HDMI 2.2 connectors looming over 2027, a hardware update of some kind that boosts baseline performance and potentially implements support for those standards seems practical at some point. Given these primarily consumer-focused improvements, an announcement at CES 2027 or Computex 2027 might make sense. As with any future product rumors, however, only time will truly tell.
