I'm curious, how much power is everyone's 3090FTW3 pulling, OC/No OC. Also, anyone daisy chain at least one of the power leads, and is it stable? I have a Seasonic 850w Gold PSU.

Not enough what?

This coming from first hand exp? Or rumors/bandwagon?

107% on the power slider is not enough.  GPU-Z shows anywhere between 400-450w of usage.  I've been tempted by the Strix vbios, but not sure it's worth it beyond benchmarking as games run well above 60fps at 4k.  

Hopefully EVGA will decide to release a VBIOS of at least 480w, the same level of the ASUS strix for these cards in time for the release of full cover waterblocks. I'd hate to be power limited of I'm not temperature limited. But then again I'd like to just be able to actually purchase a card at this point.

I have 750W and non oc my UPS only reported max draw of 630w with PC and monitor during folding@ home full load test.
after OC of card/CPU UPS reported max draw of 753w peak with PC and Monitor during folding @ home testing.
So 850 will be plenty for stock or OC

Overclock.net has most card BIOSes uploaded and logged. 3090 FTW3 BIOS reads 450W max. The Strix is 480W, but it's kind of pointless as it pushes temps into the 80's without max fan speed. Remember, these coolers are not much bigger than last year's, yet the chip is pulling 100W more. They are going to struggle.

My card hovers around 70C with auto fans on the 450W OC VBIOS (3090 FTW3 overclocked hovers around 1950 to 2000MHz, and +750 on the VRAM) even under the most stressful loads (which include Folding @ Home's new CUDA enabled work units (running all day)). Yet I have great airflow because my case has two fans on the removable side blowing cool air directly onto the card - lots of folks complain about the temps, but don't have cases with side fans that used to be standard.
 
Under full (CPU/GPU) stress testing, my rig pulls about 1KW from the wall. Idle is around 330W at the wall. Full specs in the ModRigs link. GPU only being fully loaded & overclocked - about 750 watts from the wall, GPU-Z reports 400 to 450 watts for board power, with it staying mostly right around 400W when Folding. Interestingly, while Folding I'm seeing 123% power limit in PX1 even though PX1 shows a 107% max limit (it bounces, but hits over 120% most of the time) - that's with GPU-Z reporting a fairly steady 400W board power draw.

last time the kingpin bios did not work with the 2080ti ftw3 unfortunately.
Our best bet might be an xoc from evga
 
when you compare the 3080 bios, going from 400w to 450w is a huge gain of 12.5% power.
 
going from 450 to 480 is only 6.5% gain and because of the high consumption, it wont be used properly without a waterblock.  Ideally we will get a 520-525w bios to play with

What benchmark/stress test is the best for seeing if a card is able to get the advertised power draw?  At default settings, I'm around 350W board draw and average around 1735 core in Port Royal.  The PerfCap Reason is Pwr over the entire run.
 
To see if this was an issue with the rest of the system, I swapped the card into another, updated all drivers and seeing the same behavior.
 
System 1
AMD 3970X
64GB DDR4 3600 CL16
Asus ROG Zenith Extreme
Season Prime Ultra Platinum 1000W
EK block on the CPU
Enthoo 719 Case
 
System 2
Intel 9900K @ 5Ghz all core
32GB DDR4 3200 CL16
Asus ROG Code
EVGA G3 1000W
Corsair AIO CPU on the exhaust side
NZXT H700
 
The card would draw 450W+ prior to the latest PX1 firmware update and Nvidia driver update.   If necessary I can always rip apart my ITX build which has a 10700k/2080 Super and see if that cpu/board make a difference but not sure it's worth it.

I've been playing through AC: Valhalla: Wrath of the Druids, and my EVGA 850W Gold PSU trips occasionally with a 3090 FTW3 and a 5950X.  I guess I'll have to either flip the bios switch to use less power or upgrade the PSU.

If it's a GA model RMA it - the GA originally had an issue with 3080s and 3090s that was fixed a couple months ago. Just make sure to let EVGA know about your 30 series card causing reboots/shutoffs and they should get you the fixed version.
