Discovered this the hard way when building quad GPU servers. 1080Ti has TDP of 250W per spec, yet most "1600W" power supplies will crap out and shut down your system if you fire up 4 1080Ti's simultaneously. The only brand I've tried that didn't crap out was EVGA. Supposedly Corsair 1600W PSU is also OK, but I haven't tried it. Even in nvidia-smi (which I think still averages things out somewhat and never shows the momentary peak power), 1080Ti will often jump way over the 250W "limit" when it's at 100% utilization.
