SilverStone’s latest PSU GPU support list includes a bunch of unannounced NVIDIA graphics cards, including the RTX 3070 Ti and the RTX 3080 Ti. It’s unclear whether this is a typo or simply a guess on SS’s part, but we’ll just have to wait and see:
The RTX 3080 Ti won’t be launching anytime soon, and when it does it won’t be based on the same GA102 die as the RTX 3080 and 3090. We’re likely going to see a larger die, with the full-fledged chip representing a new Titan and a cut-down variant forming the RTX 3080 Ti. I expect the announcement to come sometime in mid-2021, around Computex.
SilverStone recommends a 1100W PSU for all the top-tier Ampere cards including the RTX 3070, RTX 3070 Ti, RTX 3080, RTX 3090 and the RTX 3080 Ti, so there’s a good chance that this is just a placeholder.
