Rumour has it the top tier Big Navi card also has two power connections, with a 300W requirement.

TDP (thermal design power) for my EVGA GTX 1080 Ti SC2 is 250 W and Suggested PSU 600 W, if the top AMD Big Navi is 300W one can see a reason to go for AMD instead of Nvidia.

Personally, I'll go for a mid range with increased performances over my 1080ti but not the top range.

I do agree that the PSU is one of the core components that it pays dividends when going with higher quality and rating as it is likely to last you for several builds and is often overlooked. Always makes me wonder when someone drops big $$$ on a CPU and GPU, only to cheap out on a power supply... The life blood of the system. In the last 10 years I've only had two PSU's. My TT tough power 750 lasted me close to 6 years. Then I upgraded to a Seasonic 850 when the TT lost a 12v rail; its going on 4 years and hoping to get at least 2-3 more years out of it.

My thought when upgrading a PSU has been, estimate what your comsumotion is likely to be, then give yourself 25-50% headroom. Always buy quality brand PSU, your system and your sanity will thank you.

As for 3080's power consumption, it doesn't bother me as it's nothing I really care about. I always overclock and run watercooling to squeeze every last bit of performance I can out of the hardware.

Well aware. I thought that was well established. But I guess I should have made it clearer. Platinum is what I buy.

Do you watercool your 1080Ti and if yes do you have a viable solution?


Thanks!

And remember the memory is rated at 21GB/s and is set at default to 19GB/s. SO there is margin there too.

This will be quite noisy to cool unless you put it on water.
