How are people with 3000 series cards faring with PSU usage?

I have an overclocked 10900k and an overclocked 3090FE running from a 850W Asus PSU, no issues at all and my entire house is pulling less than 650w when gaming so I don't forsee any either.

I have the Palit OC, I moved the power slide to 109% in Afternburner as it is very power bound due to being basically reference 320w, now peaking out about 345w in HWInfo. This really helped with clock maintenance, as did undervolting in order to use power more efficiently. It now hardly every drops from 1980mhz, previously I was getting sub-1800mhz in games like Metro Exodus due to power rather than heat. Real world performance in benchmarks has increased so there's no clock stretching with the undervolt or anything like that.

Really sweet chip, even if the the Palit is a pretty basic model.

Any idea how much it's loading? Guru have also recommended 650w for 3080 which reinforces some of the sentiments in this thread

Jeez, 5 weeks on and you've still not bought one?

Nope, all I know is that I can play CP2077 for hours with no sign of any crashing or anything.
12v rail remains steady and never drops at all so it's all good
