RTX 5080 Super appears in Seasonic PSU calculator with 24GB GDDR7 and 415W TDP

The RTX 50 Super series has been in limbo for a while now, with the memory crisis and shifting priorities making a launch look increasingly unlikely. However, a new entry in Seasonic's PSU tool has brought the topic back, with the RTX 5080 Super now appearing alongside the RTX 5070 Super and RTX 5070 Ti Super that were added last September. All three rumoured Super models have now shown up in the tool.

According to the listing, the RTX 5080 Super carries a 415W TDP, which lines up with earlier rumors that placed the card somewhere above 400W. That is a 15% increase over the standard RTX 5080's 360W, and it pushes the recommended PSU from 750W to 800W in a system paired with something like a Ryzen 7 9800X3D. The higher power draw is expected to come from upgraded memory rather than additional CUDA cores, which remain at 10,752, the same count as the non-Super model.

The memory upgrade is the headline change. The RTX 5080 Super is expected to move from 16GB to 24GB of GDDR7, a 50% increase in capacity, using newer 3GB modules instead of the 2GB chips on the current card. Memory speed also gets a bump from 30 Gbps to 32 Gbps, which pushes total bandwidth from 960 GB/s to just over 1 TB/s. The bus width stays at 256-bit.

PSU calculators have historically been an early indicator of upcoming GPU launches, since manufacturers need to prepare recommendation databases ahead of release. That said, appearances in these tools have jumped the gun before. The RTX 5070 Super and RTX 5070 Ti Super showed up in Seasonic's calculator last year, leading to speculation ahead of CES 2026, before NVIDIA confirmed no new GPUs were coming. With that in mind, the listing should be taken with a grain of salt until we get some concrete confirmation.

A well-known insider said last month that the Super series is back on track, and the RTX 5080 Super's appearance completes the full lineup in Seasonic's tool. CES 2027 is currently the most cited target window, with a late 2026 announcement not entirely ruled out.

Question #1

What real-world performance benefits should buyers expect from the jump to 24GB GDDR7 and 32 Gbps memory on the RTX 5080 Super in memory-heavy workloads or gaming?

This article does not provide measured real-world performance numbers from the jump to 24GB GDDR7 and 32 Gbps memory. It states the changes increase capacity by 50% (16GB to 24GB) and raise bandwidth from 960 GB/s to just over 1 TB/s, but gives no concrete gaming or memory-heavy workload performance gains or benchmarks.

Answered

Question #2

If the RTX 5080 Super keeps the same 10,752 CUDA cores, what bottlenecks might remain that could limit performance gains over the standard RTX 5080?

If CUDA cores remain at 10,752, performance could still be limited by bottlenecks outside core count: the article notes the bus width stays at 256-bit, so memory bandwidth improvements are modest despite faster GDDR7, and the higher TDP suggests power/thermal limits could constrain sustained boost clocks. Additionally, pricing and whether the extra VRAM justifies performance are unknown factors that could affect value versus the standard RTX 5080.

Answered

Question #3

Given Seasonic’s PSU tool added the RTX 5070 Super entries before NVIDIA confirmations, how reliable is Seasonic’s listing historically and what should readers infer from it now?

Seasonic's PSU calculator has been an early indicator in the past because vendors prepare recommendation databases ahead of releases, but it has also produced false alarms before, the RTX 5070 Super and RTX 5070 Ti Super appeared in Seasonic's tool last year yet NVIDIA confirmed no new GPUs at that time. Therefore readers should treat Seasonic's listing as a plausible early signal but take it with a grain of salt until NVIDIA or partners provide official confirmation.

Answered

Question #4

If planning a purchase now, should users wait for official NVIDIA confirmation or proactively choose a higher-capacity PSU to prepare for an RTX 5080 Super?

You should wait for official NVIDIA confirmation because Seasonic PSU listings have jumped the gun before and the article warns the listing should be taken with a grain of salt. If you prefer to be cautious now, consider choosing a higher-capacity PSU since the Seasonic tool recommends 800W for an RTX 5080 Super in a system with a Ryzen 7 9800X3D.

Pricing remains unknown, but the 50% increase in VRAM on top of already elevated memory prices makes a significant premium over the standard RTX 5080 almost certain. The standard card already sits well above its launch price in the current market. Whether the added memory justifies whatever NVIDIA ends up charging remains to be seen until the cards actually surface.
