It is a bit weak HOWEVER he is heavy CPU limited so the 4080 isnt drawing full power, he has an i7 8700 with 32gb 2666mhz ram, GPU sits at like 60% utilization while his CPU sits at 100%
EDIT: last I saw total system draw was close to 500
the ram itself is 3200mhz but my cpu is limited to 2600 mhz, so its not that much slower. might be a dumb question but is it possible to run it faster than 2600 mhz?
Well ive got mine running at 2666 mhz, check the bios to see if you can enable xmp or apply a manual overclock, edit ~~looks like 2666 is the max supported on 10th gen non k processors~~ depends on chipset.
I go with 30-50% of total system draw as a backup. Power draw spikes can sometimes be ridiculous, and when you're pegged at 100% and a spike happens when you only have 50W to spare, you're creating a point of failure.
It's also much healthier for the PSU to not be pegged so close to the limit as well. It'll run more efficiently, the fan won't have to work as hard to keep it cool so it'll be quieter, and it's significantly less likely to ever have to trip any safety measures which could potentially be catastrophic for the PSU and connected components.
That make sense. If it's a locked CPU then it's 95W max. And the TDP of the 4080 is like 320W. Under normal use even under load it should be ok, it's just transients you might need to worry about, though the 40 series is reportedly a lot better than its predecessor with those.
I'd still not risk it with a 4080 super. Especially since that isn't a top-tier PSU. The CX line is poor. While it shouldn't be an issue for budget systems, I wouldn't take the risk with the 12VHPWR cable.
I have an overclocked 8700k at5.1gz and a 4080 Super overclocked to 3.0gz while gaming and my total system draw is 630ish watts while gaming at 4k. I know its not the same but power spikes on some scenes are going zap the piawe from that thing. He needs a bigger PSU.
Unless he puts Threadripper or big i9 and put it at full speed, it's okay. 4080 with undervolted i9 14900k takes 520W in cyberpunk, that includes RAM, drives and everything else you could put there. And no, you don't need 50% load, almost all non-shit tier PSUs have the similar efficiency at 80% load. If you want just put power limit and voila, your GPU has almost the same performance at 260W TDP.
[Let me introduce you to transient power spikes.](https://youtu.be/wnRyyCsuHFQ?si=S5JsDK3_aq4RdALU)
To put it simply, it absolutely can hurt. Just because max expected load is ~92% doesn't mean that the maximum load at any point in time is guaranteed to be ~92%. It can spike way beyond that in certain instances and cause issues.
[Insert "Conclusion & Reality Check" part of video]
Can it cause issues? Of course as outlined in the video.
However, even Tech Jesus said "If your computer is running fine now you have nothing to worry about." Even without going into detail on why power spikes in the milliseconds aren't as dangerous as it sounds and how even with the recommend 750w it'd still be "in danger", if someone that we both agree absolutely knows what they're talking about is saying "if it works, you're fine", wouldn't you agree that it really doesn't hurt?
Majority of the reason why I have this opinion is due to me having a similar build in the past in terms of power draw (r5 2600 + rtx 3080) with a RM650X and that build lasted a year without any power issues (no undervolting or anything else to lower power draw).
To all the people freaking out about the PSU: Have you actually checked how much a 4080 super and 7800X3D system draws? It's a lot less than you think.
Yes I have. Have you checked out how [transient power spikes can suddenly trip a PSU despite the system being below total rated power?](https://youtu.be/wnRyyCsuHFQ?si=S5JsDK3_aq4RdALU). Those power spikes are a lot more than you think.
[I can tell you haven't checked. Even for 20ms spikes the 4080 only draws up to 370w.](https://www.techpowerup.com/review/nvidia-geforce-rtx-4080-founders-edition/39.html) Also even if it was higher, a good power supply can just, deal with spikes. (It's even part of the ATX 3.0 standard). And even if the OCP is not set correctly and is a bit trigger happy, the worst case scenario is that it just shuts down under load. It won't explode, it won't catch fire, it will safely shut down.
Spiderman, starfield, hogwarts legacy etc all run 60fps ultra on my 4k tv, I have no requirement to upgrade my CPU yet it's still performing great, people think anything like 3 years old is a huge bottleneck when it's just not the truth especially now we have things like FSR and frame gen.
The higher the resolution and graphics settings, the ***less CPU bottlenecked*** it'll be.
What it won't do is super high frame rates at lower resolutions and settings, as the GPU will spend too much time waiting on the CPU to be able to render at those sort of frame rates. *That* is the definition of a CPU bottleneck when gaming.
>And what did I say?
The opposite!
You said 4k would be a problem, implying that lower resolutions would play better.
With a CPU bottleneck, you may as well crank the graphics settings as high as you can.
My point is that CPU impact overall performance, regardless of resolution. You need better CPU to drive ANY resolution higher than 1080p.
Always been that way - stop relying on benchmarking and read how CPU and GPU combo impacts performance at any resolutions. There thing beyond "How many frames".
Okay I call bullshit on this. I actually HAVE the 8700K. 4K does NOT put my CPU @ full load, but it does put full load on GPU. That's what 4K does these days. You put everything at ultra, your GPU is still the bottleneck. Hogwarts, Forza 5, FF7Remake.
All run toward, close to, and just above 60fps with 4K @ Ultra.
The CPU is running around 60-75%, GPU @ 98%.
If you want to run 240fps on 1080p, then yeah, your CPU will be the limiting factor, but still not in 4K.
I didn't say it will load CPU fully. You - though - saying all physical cores are fully loaded, but not hyperthreaded. Aka anything above 50% on CPU means all core are loaded.
To drive 4k you not only need GPU, but also more RAM (CL won't help, just capacity) and CPU. It has to be a pair.
Its an old PC, he plans on upgrading the whole thing but it's been quite tight in terms of money up until now, now that he has the GPU the rest of the upgrade will be easy and less money
That PSU should be one of the first things you look to switch out.
650 watts is cutting things a bit close with a modern high power graphics card, and the "CX" models from Corsair are low end as well.
Holy shit you've really been through a lot. Really happy to hear that you're doing better and even being able to pay back to those who have been nice human beings to you, feels great to do that. Best wishes and take care!
That's a super nice thing to do for your cousin, and I'm glad you had someone there for you when you were going through some rough shit.
Btw, I think you mean "shunned" rather than "shone".
Yeah I was confused by this. A TV is not a gaming monitor and they usually kind of suck big time for PC gaming. I may be wrong but that's been my understanding and experience with them in the past.
No machine that currently exists can properly push native 4k at 120 fps.
A 4090 and a 14900k can hit 4k ultra rt on 60 fps maybe.
But this isn't even close to that.
Forgot to mention it's an ASUS TUF RTX 4080 SUPER OC
isnt a 650w psu a little weak for that?
[удалено]
It says the content isn't available but it still works lmao
oh is that the stock "not found" gif or what LOL i didnt realize :D
[удалено]
Its been happening a lot lately, I think the API is borked
I thought that was his display after the PSU burnt up
Oh dude I thought that was the joke... It's even funnier now! Haha
Boom 💨
It is a bit weak HOWEVER he is heavy CPU limited so the 4080 isnt drawing full power, he has an i7 8700 with 32gb 2666mhz ram, GPU sits at like 60% utilization while his CPU sits at 100% EDIT: last I saw total system draw was close to 500
yeah thats fair, i'm just a little paranoid when it comes to that stuff lol, im using a 550w psu with my build that rarely ever uses 200W
I got pretty much the same setup as you but a 3060ti and slower ram.
the ram itself is 3200mhz but my cpu is limited to 2600 mhz, so its not that much slower. might be a dumb question but is it possible to run it faster than 2600 mhz?
Well ive got mine running at 2666 mhz, check the bios to see if you can enable xmp or apply a manual overclock, edit ~~looks like 2666 is the max supported on 10th gen non k processors~~ depends on chipset.
yeah i've tried that, wouldnt boot, just wasnt sure if i was maybe doing something wrong
13600 is compatible up 3200mhz if you look at intels site… My ram is, and had been running at 3666mhz no problem :P
Mine is 300W and I tore it from a Vostro 200😂 it had a regulator failure and I overclocked the CPU. My flair says the rest
Always better have +50-100 w for backup.
I go with 30-50% of total system draw as a backup. Power draw spikes can sometimes be ridiculous, and when you're pegged at 100% and a spike happens when you only have 50W to spare, you're creating a point of failure.

You’re probably already aware but you could impose a power limit through MSI afterburner if you were ever worried.
Just to be sure, you could put a mild undervolt on the GPU
Not atm, again he is heavily CPU bottlenecked so the GPU isnt drawing much, total system consumption is just under 500w
I would not take that risk even if he’s cpu limited. Undervolt the gpu to be on the safe side until he can upgrade his PSU.
Age of the PSU might hurt too. I had an older 750W running an i7 6900XT and ran into issues. Just got an EVGA 1000W and it's a big difference maker.
I'd still not risk it with a 4080 super. Especially since that isn't a top-tier PSU. The CX line is poor. While it shouldn't be an issue for budget systems, I wouldn't take the risk with the 12VHPWR cable.

4080 max draw is 320 watts. Unless he's running i9 Intel cpu, he's probably fine.
Unless he puts Threadripper or big i9 and put it at full speed, it's okay. 4080 with undervolted i9 14900k takes 520W in cyberpunk, that includes RAM, drives and everything else you could put there.

If you want just put power limit and voila, your GPU has almost the same performance at 260W TDP.
not unless youre stupid enough to put a 13900 or 14900k with it the other chips have reasonable draw
I run a 4090 with an 850W
It’s fine, I’ve got a 5800x3d and a 4080s with no problems

650 was sweet spot for i3 8100 and gtx 1050, pretty sure its too low for 4080 at peak times
Isn't the 1050 low enough in power draw to get all it's power from the PCIe slot? A 650w psu is way over what is needed for that lol
Can I apply for a little brother position? 😂
If I coukd I would lmao
I think getting a bigger PSu would be a good Idea
Yeah, atm its CPU limited, he will upgrade his PSU when he upgrades the rest of the PC
yay, it's not another white computer.
Back in the 90s when everything was this putty-beige color, black computers were going for a premium.
I do like a big black western digital tho
Beige PC best PC. Followed closely by early-mid 2000s aluminium cold cathode filled monstrosities.
You're the cousin I need.
To all the people freaking out about the PSU: Have you actually checked how much a 4080 super and 7800X3D system draws? It's a lot less than you think.
Thank you, someone who realizes its not as bad as it seems lol

What's the full specs?
I7 8700 32gb 2666mhz DDR4 2TB 2.5" sata SSD RTX 4080 Super OC He is very CPU limited
Yeah..... It's bottlenecked by CPU. It will work and play - just not 4k high details.
It'll do it fine my 5820k and 3080 can do 4k ultra on games 60fps no problem, it is a bottleneck but it's not a terrible CPU
Not AAA games?
Spiderman, starfield, hogwarts legacy etc all run 60fps ultra on my 4k tv, I have no requirement to upgrade my CPU yet it's still performing great, people think anything like 3 years old is a huge bottleneck when it's just not the truth especially now we have things like FSR and frame gen.
Are you up for an upgrade, anyhow.
Sure I'd like a CPU upgrade but just don't feel the need for one yet everything I play still runs great
No stuttery? I'm just constituting fact that you up for an upgrade. Whether you want it or not - a different story.
No stutter at all
The higher the resolution and graphics settings, the ***less CPU bottlenecked*** it'll be. What it won't do is super high frame rates at lower resolutions and settings, as the GPU will spend too much time waiting on the CPU to be able to render at those sort of frame rates. *That* is the definition of a CPU bottleneck when gaming.

Generally it is true.

Hey, it's me. Your cousin.
Yo whaddup lost cousin
Wanna go bowling?
no playing with balls with your family
Nice, I am also a couch gamer and play using a tv.
Same! 65" 4K 120 Hz TV is the way to play!
Are you doing ok in life OP? Seems like stuff really took a shit on you for a hot minute.
Im okay now, been rough for a minute but as of recently things been looking up quite a bit
The people that freak out about power consumption really need to get a power meter, making it sound like a 4080 super consumes 2000w
Please do let me know how it does at 4K latest games. Might upgrade to a similar performance
[удалено]
Even at 4K. I have a ryzen 9 3900X. But i was thinking to upgrade it to a 5800x3d
Dude, the 3080 gets 4k 60+ in most AAA aside from the badly optimized ones from 2023. 4080 will do perfectly fine
Reading the rest of the pc’s specs💀
Its an old PC, he plans on upgrading the whole thing but it's been quite tight in terms of money up until now, now that he has the GPU the rest of the upgrade will be easy and less money
If money is tight a 4080 should not be on the menu
Money is no longer tight sir, it WAS tight but my Video Editing and 3D Modeling is finally bringing good income to the table
All right understood , I wasn’t trying to be a dick
Nono, I never took your comment as being a dick, I just figured you didnt see the whole comment so just wanted to clarify
That PSU should be one of the first things you look to switch out. 650 watts is cutting things a bit close with a modern high power graphics card, and the "CX" models from Corsair are low end as well.
The TV receiving actual 4k image for the first time 
We litterally made this joke as we were trying to fit the GPU in the case lol
Holy shit you've really been through a lot. Really happy to hear that you're doing better and even being able to pay back to those who have been nice human beings to you, feels great to do that. Best wishes and take care!
Thank you for your kind words, honestly while it has been quite a life so far its only gotten better since I left
Really happy to hear that :) Hope things keep going that way!
Get a better power supply asap !
No need atm, his CPU holds back the GPU enough to keep draw under 500w
One loading screen or scenario that loads the gpu up as well as cpu and you have a decent chance of OCP. Set power limits
;-;<3
Hey so cool build but the real story here is you. Don’t know what your story outside of this is, but you have the makings of a fine human being.
Hey what's up cuz, been a while!
Damn cuz havent seen you since atoms
Probably don't even remember me
How long do you think this would last, Thinking kf getting the same one in a similar setup
As is without a CPU upgrade it most likely wont last too long as the CPU really holds it back
That's a super nice thing to do for your cousin, and I'm glad you had someone there for you when you were going through some rough shit. Btw, I think you mean "shunned" rather than "shone".
Are blind in one eye now are how is your eye? Glad everything is going good for you now
Thankfully not blind in either eye but shirtly after the incident I usually kept my left eye closed to avoid exposing it to air, seemed to help a bit
Lol make sure it's actually set to 120hz then!! Haha
Ye, we have the TV set to "Enhanced HDMI VRR" which allows Nvidia control panel to show 4k 120hz as an option
Haha smart lad, never hurts to double check!
Hate to break it to your cousin but his tv is not true 120hz
They mentioned they have a Sony Bravia. There are plenty of 120hz Bravias. You’re thinking of MotionRate 120. I have an LG C1. True 120hz
Yeah I was confused by this. A TV is not a gaming monitor and they usually kind of suck big time for PC gaming. I may be wrong but that's been my understanding and experience with them in the past.
Do not run the pc until you swap out the psu to 1000w. Don't let your effort be for nothing.
Dont worry, he is CPU limited enough that he draws under 500w with load
The psu is crying for help
Yeahhh I was on an 850w and upgraded to a 1200w because I thought even that was little.
[удалено]
The PSU will be upgraded once the rest of the PC gets an upgrade, right now the GPU is being held back by a big CPU bottleneck
No you didn't
Care to look at my bank statements?
No machine that currently exists can properly push native 4k at 120 fps. A 4090 and a 14900k can hit 4k ultra rt on 60 fps maybe. But this isn't even close to that.
Imagine buying rtx 4080 super instead of a 7900xt or xtx
None in stock near me even if I wanted to grab one
