Hey,
Im waiting to the card arrival next week..
But i keep seeing reviews/posts of people say that the card crush while gaming with 750w psu..and the card taking 450w+..
Do i need to be worry?the recommended psu is 750w according to the product page..

And what do i need to expect in therms of temps and noise (stock..no oc for now)..coming from 3080 aorus extreme that was not silent..but acceptable..

Thanks!

Thanks,
I got 604w (9700kf)..why is the x1.5 for?its not supposed to be accurate?

Is turning of the card RGB should help a little?(i dont care about that...)

Thank you!
450-530w is unbelievable!is it the normal or oc bios?
And if that so..why is the recommended psu is 750w?you dont need to undervolt the card in order to use it with the recommended spec...

Thanks.
On the card there is a physical switch-normal bios or oc bios ..so if the normal one draws 530..how much does the oc one draws??

As far as I know that switch only affects the fan table and not the actual power limit of the GPU so it should draw the same power.

Our minimum recommended power is typically going to be the same as NVIDIA's recommended power supply.  On the specs page on GeForce.com, NVIDIA usually lists what the system configuration was tested with when they determined the minimum power requirements, and you can compare that to your system.
 
For example, go here to find the 3080 Ti, and you'll find NVIDIA's configuration is: "Requirement is made based on PC configured with an Intel Core i9-10900K processor. A lower power rating may work depending on system configuration."

Interesting. Although the FE 3080 Ti has a peak power a lot lower of 412W vs 531 and at gaming the FE consumes a max power of 352W vs 452W for the FTW3:
 

 

A PSU is most efficient at 50% load, even then some of its output will be lost to heat.  80+ Gold means the PSU is rated for 80%+ efficiency, and Gold should be around 87% efficient at least, so that would mean a 750W Gold PSU can support up to ~652W of actual consumption.  In a stock system - no overclocking, messing with power limits - the 750W recommendation will work.  Just realize you don't have a lot of headroom if any.
 
I'd personally recommend looking for at least a 1000W PSU if building a new system with high end GPUs and CPUs in mind today...  but keeping in mind the 50% is the sweet spot, 1200-1300W PSUs might be closer to the mark for ultimate efficiency.  Pick a single rail PSU over multi rail.

This is partially truth. The power efficiency is output_power/input_power, but the output power is actually 750W DC, so when the power efficiency is lets say 80% on a PSU that means the output power is 750 W DC and the input power is 937,5 W AC
 
For example my PSU at 100% load delivers 749,38 W DC and draws from the wall 844.02 W AC. which means a power efficiency of 88.79% which is aprox 89% power efficiency which is the rated efficiency for a platinum rated PSU

So, if things wont work well with my 750w..
Is the Corsair gold rm1000x s ok?or should i go for antec signature platinum 1000w ?(around 30 bucks diff)

I recommend a power supply of 1000w or more. I think that it works stably even at 850W depending on the CPU.

750w is more than enough for normal use, unless you OC the hell out of your cpu. Most people overestimate the wattage on a PSU. There were people running the kingpin 3090 on 700w just fine. Your overclocking headroom is lower, but in normal gaming use you will be more than fine with 750w. Just make sure you have at least a gold rated.

So how does it get with the review saying it takes over 450w while gaming?
It sounds like this model is very very power hungry compared to other models..even compared to some 3090 models..

Thanks - looks like I misunderstood how PSUs are rated, so efficiency affects wall draw and PSUs can always output what they're rated for.
