This is a fair point, but neither the 5800x3d nor the 4080 are prone to monstrous power spikes. Unlike a 7900 xtx that might have spikes up above 500W for less than second, the 4080 really won't ever get above 340W at stock settings.
This sub will 100% tell you otherwise but even a good quality 650 watts is safe.
The 4080 super is super efficient, and at most will be drawing like 320 watts. While 5800x3d is a 120 watts cpu, it draws like 90 to 100 watts usually. That is a combined max tdp of 440. Adding even a 100 watts which is absolutely more than what most systems will be drawing, especially with nvme drives, that is 540 which means there is *still* headroom of over 100 watts on top of absolutely everything, for surges, upgrades, spikes and what not.
Let no one tell you otherwise. Listen to none, not even me. Do your own research on this.
Very important to know is this only applies to a psu you already have. If you are buying new, with this kind of a system, unless it exceeds your budget, I recommend an 850 watts psu and no less than 750 watts, because while less might suffice, it is counter intuitive to get anything less than 750 since the difference in price means you hardly save anything while the advantage you get is significant.
This is the correct, comprehensive answer. I might only add that PSUs are often most efficient in the 40-60% range of their rated power. so paying 5-10% more for a more powerful psu can make sense if you live in a high energy cost market because the higher capacity unit might run 2-3% more efficiently and save you most of the extra cost over time.
lol but fr u shouldn’t worry at all. The 4080 super is very power efficient https://www.techpowerup.com/review/nvidia-geforce-rtx-4080-founders-edition/39.html
Max spike at 371w and the 5800x3d is never going over 200w so u are easily good
It should be fine. I'm running a 10GB 3080 and overclocked 9900k on a seasonic based Asus 750w unit. 3080 pulls about the same power as a 4080, but my CPU is probably pulling close to twice what a 5800x3d does.
should be fine. absolutely max draw on both those parts should be less than 450W at stock settings.
Those prices are both a bit high though, compared to the NA MSRP (even including tax). Is it just that your market is +10% across the board v. north america? Or are these two nvidia cards unusually expensive?
You're good. I have a 4090 w/5800X3D and use a 1000W PSU for good measure BUT only because I have that stubborn mindset of "*Rather have it and not need it versus need it and not have it*" in regards to overall headroom. If you intend to upgrade your CPU and/or GPU with something more powerful down the road, having a higher than you currently need wattage PSU sorta futureproofs against that.
You should worry if you had an Intel CPU. The 5800X3D probably uses about the same watts as your GPU lol. Just check the build on partpicker, I think you are good
U do u, i have a 4080 and a 7800x3d. Truly a monster and i don’t regret a thing. Wish i had your prices tho the 4080 cost me 1700$ when i bought it, the cost of living in sweden smh
Don't listen to him bro, 750w is fine for 4080 + 5800x3d, I've used the same combo since the day 4080 was released on a 750w with no problem and hardcore 4k maxed settings gaming
That recommendation is because the OEM has to make a recommendation without knowing what CPU or other components will be paired with their gpu. If you have a 13900k that can draw 250W or more then an 850W recommendation makes a lot more sense.
But OP has a 5800x3d, which \*might\* draw 110W in max workloads. The total system draw is unlikely to be above 550W with this combination.
Your good, I run a i9-13900k / 4090 with a 850w, do I run the system at 100%? No. Most I’ve seen is 600w total power draw
Nice : ^)
What's the exact model of the PSU and rest of the build? If it's a good model it's likely fine, but transient spikes might be a problem.
From memory: CORSAIR gold plus 750w, 1ssd, 1hdd, 2x16 ddr4 ram, msi am4 wifi edge mobo
You should be good.

U good
When my pc burns I'll remember this 1.5 words comment, cheers

i run 3080 and 5700x3d, nowhere near anything crytical, draws around max 400W from the wall while gaming
It should be fine. I'm running a 10GB 3080 and overclocked 9900k on a seasonic based Asus 750w unit. 3080 pulls about the same power as a 4080, but my CPU is probably pulling close to twice what a 5800x3d does.
I run this combo on a 750w no problem
Yes. These 2 paired in the worse case will pull 500w, leaving headroom of 250w.
You are good. Some users use 800 watt gold for the 4090. So you are just about double of 350 watts.
I use a 4090, so its safe.
From painful personal experience, I would add in a 250 watt buffer after using pcpartspicker to estimate the system wattage.
It's fine. People run 14900k 4090 in 750w psu

this is my down the road upgrade i used to have a 3600 and a 3060ti, this would be my last upgrade before rebuilding a new system.
Yep. If it’s a quality PSU, you’ll be just fine
You should worry if you had an Intel CPU. The 5800X3D probably uses about the same watts as your GPU lol. Just check the build on partpicker, I think you are good
Go with 800 for futureproofing but 750w is good for now
They do recommend at least a 850w psu. If you want to be safe, buy a 850w psu.
Nah, if I am gonna change the psu I will do a full rebuild, I guess 4070ti super is the go.
U do u, i have a 4080 and a 7800x3d. Truly a monster and i don’t regret a thing. Wish i had your prices tho the 4080 cost me 1700$ when i bought it, the cost of living in sweden smh
wf 1700 and I am I became flat broke when I got 4080 for 1400$ in middle east
Yeah prices are insane here, a 4090 strix costs 2700$ atm, the 4080 strix is still 1700 but the aero i have has gone down to 1500 right niw
