But I have a high end, 80 plus cert Thermaltake which has been great thus far, and. I suspect exceedes the engineering design margin Nvidia has in their requirements.
Kinda late response, but if your PSU is actually good, it will turn off if power is not enough. What makes a PSU good is stability in power delivery and ensuring that your components stay safe. Do not try to push over the limits of the PSU, because you will damage it. It’s always better to go over than to be under on power requirements.
A poor PSU will try to deliver beyond its actual capacity, go unstable and could damage your system. Just be careful because Thermaltake has good PSUs but also bad PSUs (check Gamers Nexus for example, they’re actually very illustrative).
I’m on the same boat, if getting a 3080 or waiting for the 4080. Nevertheles I currently have a 2060 12GB, so my starting point isn’t the same. I generally have as a philosophy to run 1.5/2 generations back near top tier (for example, I’m running a 3700X, and probably will jump to a 5700X3D when 7000 will become superseeded by next gen processors). Nevertheless GPUs prices have been so crazy that getting an acceptable GPU for a decent price has been a nightmare, so I got the 2060 12GB (TBH it’s doing a very decent job, I play with a 1080p monitor scaling at 140, almost everything ultra, and I get 25-30fps mostly everywhere except at busy custom airports like KLAX with the PMDG 737-800, which is my test).
If you’re in the US, I’d wait for a 4080. MSRP is almost as a 3090Ti, it’s a superior GPU and ensures more years of supported technologies. In my latitudes, I’ll probably get a 3080 and live with it.
Best!
