Unannounced RTX 50 Super GPUs Listed with TGP on Seasonic Calculator

According to a report by Tom’s Hardware, the power consumption values for NVIDIA’s unannounced GeForce RTX 50 Super series have been listed on the PSU capacity calculation tool provided by power supply manufacturer Seasonic. The listed products include three models: the RTX 5080 Super, RTX 5070 Ti Super, and RTX 5070 Super.

Seasonic’s PSU capacity calculator is a tool that allows users to select components and determine the recommended power supply capacity. Within this tool, the aforementioned three products are selectable, with their respective Total Graphics Power (TGP) displayed.

According to Seasonic’s data, the RTX 5080 Super has a TGP of 415W, the RTX 5070 Ti Super is listed at 350W, and the RTX 5070 Super has a TGP of 275W. These figures represent increases of 15%, 17%, and 10%, respectively, compared to their non-Super counterparts.

The RTX 5080 already features a TGP of 360W and utilizes the “GB203” GPU die, which has all Streaming Multiprocessors (SMs) enabled. Therefore, the Super version is expected to achieve performance improvements not by increasing the core count but through higher clock speeds and increased memory capacity. Previous leaks have suggested the possibility of replacing the GDDR7 memory with 3GB modules, potentially increasing VRAM capacity. Although the power consumption of GDDR7 itself is relatively small compared to the board as a whole, an 8GB increase in VRAM capacity would likely have an impact on the TGP.

For the RTX 5070 Ti Super, the TGP rises from the existing RTX 5070 Ti’s 300W to 350W—a maximum increase of 17%. Similarly, the RTX 5070 Super sees a 10% increase from 250W to 275W. These models typically ship with some of their SMs disabled, and the Super versions may enable additional SMs. In addition, expanded power margins could allow for higher clock speeds.

Tom’s Hardware emphasized that these figures have not been officially confirmed by NVIDIA. The inclusion of these GPUs in Seasonic’s calculator may stem from either information provided by NVIDIA or provisional values based on leaked data. Whether these products will be launched as planned or if their TGP values will match these numbers remains uncertain.

The RTX 50 series was initially unveiled in January 2025, with the RTX 5090 and RTX 5080 followed by the RTX 5070 Ti, RTX 5070, and RTX 5060 series released sequentially. NVIDIA has yet to make an official announcement regarding a mid-cycle Super refresh, nor has there been any mention of these products at major trade shows. However, the listing by Seasonic suggests that NVIDIA may be preparing for something behind the scenes.

Reliability of Seasonic’s Calculator

Seasonic’s PSU capacity calculator is widely used as a reference tool for selecting power supplies. When the company lists data for unannounced products, it typically relies on information provided by chip manufacturers or publicly available specification sheets. However, it remains unclear whether the TGP values in this case were directly provided by NVIDIA or independently gathered by Seasonic.

Past leaks of this nature have occurred on several occasions, with some proving accurate and others differing from the final product specifications. As such, this information should be treated as preliminary figures from a leak.

Market Impact and Future Outlook

The RTX 5080 Super’s TGP of 415W represents a 15% increase over the current RTX 5080. This figure approaches the power consumption levels of the RTX 3090 Ti’s 450W and the RTX 4090’s 450W, highlighting the upward trend in power requirements for high-end GPUs across generations. For power supply selection, 1000W units are becoming increasingly standard.

On the other hand, the RTX 5070 Ti Super’s 350W TGP significantly surpasses the RTX 4070 Ti’s 285W. The increase in power consumption in the mid-range segment could raise concerns for users regarding system cooling design and electricity costs.

If NVIDIA proceeds with a Super refresh, possible methods for performance improvement include increasing the core count (enabling more SMs), boosting clock speeds, and expanding memory bandwidth. For the RTX 5080 Super, which already uses the fully unlocked GB203 die, the enhancements are likely to focus on clock speeds and memory. If power requirements exceed 410W, larger cooling solutions and custom PCB designs from AIC manufacturers may become necessary.

Editorial Opinion

The leak on Seasonic’s calculator is noteworthy as it hints at the potential existence of a Super refresh for NVIDIA’s RTX 50 series, possibly scheduled for the latter half of 2026. In the short term, the widespread dissemination of this information could prompt adjustments to current inventory and pricing strategies. Consumers considering the purchase of an RTX 5080 or RTX 5070 Ti may opt to wait for the Super versions, potentially impacting supply and demand.

In the long term, the steadily increasing power consumption of GPUs is becoming more apparent. Mid-range models requiring 350W and high-end models demanding 415W are likely to accelerate the trend toward larger power supplies and advanced cooling technologies. This may also influence power supply manufacturers’ product planning and the design of PC cases with optimized airflow.

While NVIDIA continues to improve efficiency in its architectures, it remains to be seen how these TGP increases will affect product competitiveness. The editorial team believes that these TGP values should not be taken at face value until NVIDIA officially confirms them.
