how big of a power supply

I did some quick googling and it seems like every generation the recommend PSU jumps 100W. Obviously this cannot go forever there has to be a ceiling. 

in 10yrs I dont think that 10,000 watt power supplies will be required, because that would impossible. 
 

 

 

Are you looking at TDP, or actual GPU power consumption?

 

TDP wise...

GTX 680 (2012) -- 195W

GTX 780 (2013) -- 250W

GTX 980 (2014) -- 165W

GTX 1080 (2016) -- 180W

RTX 2080 (2018) -- 215W

RTX 2080 Super (2019) -- 250W

RTX 3080 (2020) -- 320W

 

Delta (2016 ~ 2020) = ~155W

I am upgrading to 5900x when in stock but keeping my 2070s.  I am going to be giving my 3700x + case/PSU to a family member. 

 

I dont think that I will be upgrading to a 3x00 series card anytime soon. Probably wait until 4x00 series cards. Given the linear increase in power requirements  for the cards and the long life time 

and warrenty does it make sense to go crazy and get a over powered PSU (1000+)  to give me some head room? 

 

I only this is wildly speculative about hardware that is not even in development, just want to know what people think.

With the way rtx 3000 has power spikes, if Nvidia doesn't fix it a 1000w+ psu wouldn't be a bad idea

Well the RTX 3000 series is just not very power efficient.

That said, it has a lot more CUDA cores and RT cores compared to the RTX 2000 series.

 

If the RTX 4000 series is going to use the same node / technology as the RTX 3000 series, power should go back down.

You should be covered with a ~850W.

I don't see the need to get a 1000W ..... unless the GPU somehow pulls 600W ~ 700W all on its own without physical mods (e.g. shunt mod).

I was looked at recommend PSU, like a said, it was very quick and dirty googling. 

This list is very helpful, It looks like a 750W or 850W should be plenty
