- In this video, I am going to show you how to find out how much power your RTX 4090 really needs. This is an important step if you want to avoid disappointment and get the most out of your new card!
Just adding VSync option and easy undervolting can improve using experience. And how to make your GPU silent.
The same rule applies to any other card that has more power then your monitor needs. Cards like 4080, 4070 Ti, 3090 Ti, 3090 and ect.

Wow, first video on YT where someone is showing actual power consumption without extra talk however with condition accurate for most players (144 hz on monitor)
Thank u for that simple video!!!
Extra question: Can u share info what it your power consumption while doing non-game activities like web-browser,YT? Plus what is your CPU?
Hey, glad to hear that!
At idle GPU drains 20-30W, 4k video playback - same 20-30W :D
CPU - 13600K, you can check my build on my channel - th-cam.com/video/NAcAGLOJxXY/w-d-xo.html
Wonderful Content Exactly what I was looking for.!
Glad it was helpful!
@@fidalfidal9837 thanks for that
What were you looking for exactly? A palliative that would make you love the 4090 for both performance and p.consumption? Too bad you won't find it here nor in any other video; want a very good 1440p gpu that is also p.efficient? Go 4080. 4070TI would be great too if it had better memory specs
@@sandbox8717 Nope your assumption is wrong, and exactly opposite of what I was looking for. 4080 at 1200$ no thanks, the 4090 is way better value for all it offers. I would rather even get the 7900XT at 800$ than a 4080. Also I play in 4k mainly not 1440p or 1440p uw. Last part I do agree though the Vram and bandwidth really hamper the 4070ti.
Der8auer also shows how power efficient the 4090 is "for what it offers " when tuned right.
@@johnarigi6274 even if you set your 4090 up with der8auer efficiency curve it's drawing AT LEAST 350w therefore, as stated in my previous comment, you can't get both high fps and low wattage in general, unless you're playing exclusively something like a moba or...(I said LOW WATTAGE, not POWER EFFICIENCY!). Therefore it's not clear what you were looking for when watched this video, since there the owner is basically saying: "look at how low the power draw is, they're all lying", then you look at gpus usage and it sits at 60% at best.... thx to my ass, every gpu draws significally less as soon as you drop the load, here's a hint: since the load is extremely low he could prob get away with a 4080 at around 85% load and draw even less, also saving at least 400eur like this; incredible right?!
that's why ppl chose a gpu based on the resolution they're playing at, instead of going straight for the top end gpu....lol
Also the comparison between nvidia and amd is just inappropriate: the topic of the video is energy consumption at X performance; if you type "that's exactly what I was looking for" in a context like this1 it basically means you're a person looking for a "low/moderate" wattage gpu, and this is definitely NOT the 4090 profile.
From this pov nvidia is just better hands down: the 7900 xtx draws like a 4090 with 4080 perf, while the 7900 xt drinks like a 4080 but fermorms like a 4070ti; I would definitely pick a 7900xt over a 4070 ti but for the profile you described the 4080 is THE pick; ofc the 4080 it's a maxed 1440p gpu, I wouldn't buy it for 4k unless you're playing stuff like mobas, diablo, hollow knight, console emulators in general....
great content, and a new sub :) btw did you try removing fps cap? how much power would it pull in that case? would it go over 500w?
Thanks! Maximum consumption that I had - 450w
Would be interesting to see all these benchmarks again with an undervolted 4090. Setting a power limit only saves you power, when close to 100% usage. But when the card is at lower loads (which will happen all the time, if you cap fps), then setting a power limit changes nothing about power usage.
For example, you could set a standard undervolt for the 40 series cards, by pulling up the frequency curve in MSI afterburner by 150-250 mhz and then capping the voltage at 900-950mV. This should bring a 4090 at 100% load down from 400+ to around 300 watts, potentially even somewhere around 250-280. Expected performance loss with an undervolt like that is only 5-8%, which you won't notice anyway, unless you are staring at the fps counter.
I agree with you, maybe I'll try it in a few games a bit later
Yes great video, that is were the beatiful old tecnology of V-Sync comes on, it caps your frames to your refresh monitor speed, and it not only consumes less power, it just keeps your cpu and gpu way cooler allowing to keep keep them healthy and inproves a better lifespan trhu the years to come.
This is with 100% power target/without Afterburner settings? If so, that card doesnt really need more power then my 4080... That would indicate that power consumption scales pretty much linear with the 40series...
Thanks for your video! 💙
Yes, it was 100% power target with default settings.
4090 needs more power when you play 4k@100+ fps, than it can use up to 450w, but I usually limit it to 300w with almost the same performance, like i showed in the end of the video :)
@@trysometech52 Thank you!
that was exactly what I was looking for...
I'm using 4k 60hz monitor , thank you so much.
i have a i7 13700kf with a 850w psu corsair rated gold , can i run a 4090? id really hate to get a new psu since this is a prebuilt would like to keep my system as it is just change the gpu currently using a 4070 , been researching seems people ruin 4090 on 750w to 850w but i so far cant find any videos of it so not sure what to make of it , will my system be ok with 850w i7 13700kf not overclocked and a 4090?
Hey, with an non-overclocked CPU you should be fine. I've been using 13600k with 4090 for a while on an 850w PSU.
Also I'd like to recommend you to undervolt the CPU and GPU, after that you'll get almost the same performance and your PSU will be easier to handle.
one thing i want to ask , can i connect two 1000w pc on single extension board , on ehave 4080 and other have 1660 super , my extension board is max at 10amp , 250v
Dunno man, can't say for sure. That's really depending on quality for your extension board.
But on the other hand, your 2 PCs use as much power as a kettle or hairdryer (they usually drains around 2000w).
4090 are power efficiently and beast of performance
the 4090 is indeed very efficient, though not by capping your frame rate, but instead limiting your power consumption. The 4090 still delivers 95% of its performance even when limited to 70% power consumption. As for the reason why you would want 300+ fps when your monitor is 144hz, that is because when you have significantly higher fps than your monitor refresh rate, your GPU can let the monitor display the most recent generated frame when the monitor is about to refresh and significantly reduce input delay. This is especially important in FPS games, hence you never see esport players or streamers use V-sync in FPS games.
True, but this rule works if you have a 60Hz monitor and disable V-sync, you'll notice it immediately. For a 144 monitor, the difference is not that high: 1-2 ms. For an Esport player it might matter, but for the rest of us it doesn't :)
a shame you don't have the 13900k so this test could be even better, i wanted to get both but those 2 together must go to 600 watts at least, right now i'm at 250 combined
thanks for test anyway only person that actually did it lol
Yeah, i was also surprised that no one talks about it. At least i didn't seen that
And 13900k would be overkill for me :)
Just what I was looking for so it basically runs low power just like any other GPU playing a little demanding game and runs high when needs to act like the monster that it is. I figured this would make sense but I couldn’t really confirm anywhere never had a gaming PC and didn’t have enough confirmed knowledge about silicon. Best of both worlds, nice to know. Just curious is your 4090 under volted and curve optimized? Don’t think you would ever see it go over 350 if you had that in check
I just use Power Limit at 69%, you can see that in the end of the video. Power draw is around 300 Watts at peak load, and performance is almost the same. As far as I know, it’s the best way to undervolt it
@@trysometech52 undervolting actually makes the chip more efficient, think of it as fine-tuning beyond how it comes from the factory. Power limiting is just that preventing it from going over a certain limit which works really well enough though with the 4090 because it only loses at most about 10% from 350 to 450 W. Might be something to consider. Point is if you’re already power limiting you only have something to gain by doing the other, I’d say best is to do both
@@ChiquitaSpeaks usually - yes, but i've seen a guy who made a lot of tests and in result he said that power limit on 4090 is the best way to undervolt, cuz here i lose around 5% of performance
Many, many,many thanks for your video 🎉
My 4080 uses around 240 to 280 watts with v sync
My 2070 super takes around 250 watts at full blast stock clocks, overclocked i measured it at almost 400 watts
My 1080 ti has used 410 wtt massively
@@Sonflixv2 my current 3080 uses 500 if I let it 😅
Is it just voltage and max power settings turned up or both that and an actual overclock @@Sphyxx
@@Sonflixv2 it's an evga ftw 3 ultra 3080 and it might be the overclock bios I don't really know what they adjust with it turned on but it sucks power, in normal gaming on 1080p it uses around 200-300 depending on game and usage what I've seen max is 60% with palworld every other game has been around mid 40s and maybe 50 (I know overkill card for 1080p but I got it as a gift from a friend)
Hi thanks for the video just what i wanted. would of liked the data numbers to have been 2 or 3 times larger as thats why we are here not to see the game. cheers
Fair enough, i'll keep that in mind next time. Thanks
@@trysometech52 subbed thanks
Oh wow that is some insane efficiency holy cow
I've been a bit confused because tech power up's testing had similar results to this one but other efficency related youtube videos I've seen had much higher power consumption even at 60fps capped. I guess those were probably 4k? Or some extreme factory over clocked model like the Palit version that asks for a 1200W psu
Hmm, probably all factors that you mentioned: OC GPU mode, 4k and also depending on a game. But anyway, even with uncapped FPS and PL at 69%, I never seen more then ~310watts
@@trysometech52 I have a zotac 4090 gaming w i7 13700k, maximum I archive was 372w running flight simulator 99% usage GPU 4k 120hz samsung Q90B TV running at 180fps, will use vsync now, thanks for the tip
Look like 4070Ti is just enough for 144Hz 1080p 😂
Is a 850w psu enough?
Yeah totally. I even managed to run it on 700w PSU :D (check my first video)
@@trysometech52 Including a stock i9 13900K with RL Corsair? I have a Corsair RM850E 850W 80+ Gold. I play at 1440P/165Hz. Thank you so much!
@@javigarcia5278 Hey, for games it should be enough, but if your CPU & GPU will be on 100% load (in theory), it's gonna work on limits. Just keep that in mind. I hope your 4090 does not drain 600w like ASUS ROG :D
Not even running 4k, whats the point of this test?... use 4K (through dsr or native) and these numbers are entirely different.
I explained why I chose that resolution, but apparently someone skipped directly to the benchmarks. Info regarding 4k res was also mentioned.
so it depends on the load right ? Just need to be sure of that fx if I just browse the net, facebook and stuff like that, wathcing a movie that it doesnt draws 500 watts or more ^^
Right. Without any load it drains around 40watts
7900xt costs 700 bucks while the 4090 costs 2000 bucks.....7900xt doesnt use more than 320w no matter the resolution.....4090 can go 400 plus depending which game u play.
to be honest i would never get a 2000 dollar card that can get fire into my pc....i would rather get the 7900xt ffor 700 bucks and game for 4 years while waiting for a better card that uses less power while being a safe and beastly card at the same time
Just build my new pc, and it eats 860w~ in Atomic hearth with 240fps
And it's kind of scary, since I got power suply with the new 600w cable but only for 1000 watts😮
Holy cow! Probably 13900K? :D
I don't know man, just not sure how necessary 240fps in single game. Probably I'd limit it to 120-140
Or use power limit for GPU \ undervolt for CPU. Performance will be almost the same, but better temps\less power consumption
cannot see the consumption
0:59 at the left top corner
My 4080 uses more than the 4090 why is that i use v sync too
Because 4090 is more efficient. For example, it will show much better results at 100w vs 4060, same rule works here as well
Yeah power consumption is now a thing late utility bill inflation. Some people are switching to APUs because of this reason.
True. Lucky me that in Hungary electricity bills are not that high
The utility bill won't add up much because ~400W is a very insignificant power draw. If you crank a GPU at 400W 8 hours a day, getting a more efficient GPU that achieve the same result for 200W will save you around 5$ every month.
@@Phiiiiiiiiiiiii sounds good, but check electricity prices in Germany and count again :)
@@trysometech52 Hydro price in Germany cost 94.8 euros per MWh, which is 30% cheaper than the number I used for my first calculation. So, roughly 3 dollars per month saving
@@Phiiiiiiiiiiiii where did you get these numbers from?
i think you miss the point if you can achieve the same fps with a cheaper and slower card
u r basically paying for gpu resources that you are not using by enabling vsync
My point was that every reviewer tells us about constant 450W power consumption on the 4090, but it really depends on your monitor or TV
@@trysometech52 yea that's the point I am making too if you have a lower refresh and lower resolution monitor why waste money on 4090
@@crescentmoon256 for example, I have a monitor (which was in the video), where 4090 is overkill (most of the time), but that the same time I have 4k@120 TV, where I need that power of 4090 :)
Or maybe someone wants 4090 right now, and upgrades the monitor after that
@@trysometech52 but at that point u will draw that power closer to what reviews say, the power advantage you showcased will only manifest by engaging vsync Or limitint you graphics card by other means like undervolting, frame limit etc
for most people 4090 is just not a realistic choice, it's performance is great but it's best suited for people who target 4k which a slower card can't really match/ provide
😃 but i guess your showings will help people that dont know or starting to get into pc 👍🏻
@@crescentmoon256 yeah, totally agree :) I usually use undervolt, so power consumption is near 315W with almost the same performance. Still better then 450 :D
Shiiit, maybe i jumped the gun with the 4080. Im only using like 50-80 watt less.
And maybe I was in a hurry to buy 4090, cuz not using it as often as I expected :D
