Preliminary TDPs of NVIDIA's GeForce RTX 50 "Blackwell" Gaming GPUs including the RTX 5090 & RTX 5080 have been listed by Seasonic.
In addition to the AMD Radeon RX 7000 "RDNA 3" refresh models, the Seasonic Wattage Calculator has also listed the NVIDIA GeForce RTX 50 "Blackwell" gaming GPUs. The manufacturer lists five models which include the GeForce RTX 5090, RTX 5080, RTX 5070, RTX 5060, and RTX 5050. Just like the previous post, we should mention that these graphics cards and their associated TDPs are preliminary and should not be considered final specs.
Starting with the top GPUs, we have the NVIDIA GeForce RTX 5090 which will be replacing the RTX 4090 as the next-gen flagship. Currently, the NVIDIA GeForce RTX 4090 has a TDP of 450W and the next-gen model is suggested to go even higher with a 500W TDP, a 50W increase (+11%). NVIDIA is working on brand new cooling solutions and PCB designs for its Blackwell flagships such as the RTX 5090 and RTX 5080 so if the company is indeed going for higher power, then the necessary changes will have to be made for the new Founders Edition designs.
The NVIDIA GeForce RTX 5080 has been listed with a TDP of 350W which is once again an increase over the 320W TDPs for the GeForce RTX 4080 SUPER and RTX 4080. This marks a 30W increase in TDP (+9.3%). The RTX 4080 SUPER was unaffected by the core count and memory spec bump over the Non-SUPER variant but the new Blackwell core might need more power to deliver increased performance.
