Just when it looked like the memory crisis had quietly killed NVIDIA’s Super refresh, the RTX 5080 Super showed up where these things always seem to show up first: a power supply calculator.
Seasonic has added the RTX 5080 Super to its PSU wattage calculator, listing a 415W TDP, 15% higher than the standard RTX 5080’s 360W. That figure lines up with earlier leaks pegging the card above 400W, and it joins the RTX 5070 Super and RTX 5070 Ti Super, both of which Seasonic quietly added to the same tool last September. With all three now listed, the rumored Super lineup is technically complete, at least on paper.
The headline change isn’t clock speed. According to prior leaks, the RTX 5080 Super is expected to jump from 16GB to 24GB of GDDR7 by moving to newer 3GB memory modules instead of 2GB chips, a 50% capacity increase on the same 256-bit bus. Memory speed reportedly climbs from 30 Gbps to 32 Gbps as well, pushing total bandwidth past 1TB/s. CUDA core count is expected to hold steady, which means the extra power budget is almost entirely funding faster, denser memory rather than more silicon.
This is the second time the Super series has shown up in Seasonic’s calculator only to go nowhere. The RTX 5070 Super and RTX 5070 Ti Super appeared there months before CES 2026, and NVIDIA then confirmed there would be no new GPUs at the show. We covered that whiplash back in February, when the series looked all but shelved in favor of AI silicon and RTX 60 planning. A well-known insider has since claimed the Super family is back on track, and this listing is the first bat signal to back that up.
A PSU calculator entry confirms nothing except that Seasonic’s engineers needed a wattage number to plan around, and that number has to come from somewhere. It’s a good early indicator, historically, but it’s also produced false alarms before. Given the DRAM and GDDR7 supply situation right now, with the RTX 3060 12GB having to relaunch at its original 2021 MSRP just to give budget buyers something to buy, NVIDIA adding 8GB of extra VRAM to a mid-cycle refresh is either a bet that memory prices ease by early 2027, or a decision to eat the cost and pass it on.
If the Super series does make an appearance, CES 2027 remains the most cited target window. Until NVIDIA says otherwise, treat every one of these numbers as fictional. (Ed: we’ve written that sentence about this exact GPU series at least four times now, and at some point that stops being a caveat and starts being a running joke.)
