Neither CPU cores and GPU at 100%

Sure. Something like a 3080 can pull 400-450W at full tilt. If you don't have enough wattage, between that and other components like CPU, RAM, storage, RGB, etc., then, yeah, you can easily be perf capped.

Fak, might be. It was at 330W when this occured. You know any way I can measure that problem?

does the PSU in any way tell the GPU that there's no more power to be drawn, though?

 

in my experience, it's just been hard shut down, not throttling

GPU cant know if PSU is the limiting factor, it simply would shut down if PSU was the problem. PWR is board power limit, not PSU.

Woah, ok so the motherboard could be a bottleneck. I have a ASUS ROG B550 F GAMING

Nope. PWR is Graphics card power limit, motherboard cannot provide more than 75W to graphics card as it is the absolute limit of PCIE power delivery.

 

Even the cheapest motherboard has to provide 75W through PCIE, even the best motherboard wont provide much more (even if motherboard was capable, GPU BIOS is locked to not draw any more than 75W through PCIE).

Okay? Says Board power draw is 350W. So what does it mean by board?

Your graphics card.

PWR just means the power limit that has been programmed into the card's BIOS has been reached. In MSI Afterburner you can increase the power limit by a couple %, if you want to go further, you need to shunt mod your card. This has nothing to do with PSU, it's just a limit the GPU manufacturer put in place, because the VRMs aren't specced to handle more power. 320W is the limit on regular 3080, your OC card probably has an increased limit at 350W. If power wasn't limited, the MOSFETs would go bad all the time.

some game pins the GPU at 98-99%(common), some at 100% (rare), and i've seen some at 95% (rare)

 

this might just be normal

this add to this (seemingly ignored) answer, board power does not in any way affect "GPU usage" parameter

that has to do with task scheduling, i think, which isnt affected by power limit

for example, i can limit my GPU to 50% power limit, and the GPU usage would still be at 95~100% in games instead of 50%, so i doubt it's anything to do with power at all in this case

dont think OP said they're using a 3080, it was an example given by chris.
i don't think what GPU OP is using was mentioned.

edit: it was in the title, im blind lmao

Power limit has a direct effect on GPU core clock speed. GPU would run higher frame rates when power limit wasnt hit until gpu/cpu

/other bottlenecks were reached.

yes, but it doesnt really affect the "GPU Usage" parameter was my point

your performance will drop definitely, but "GPU Usage" would stay the same, from my experience

@Question mark?? I have merged your threads together. Please stick to a single thread for your troubles/question surrounding the same topic.

Yes, my GPU TDP is at 350W. My GPU is currently running at 60C as the picture suggests. You think is should temper with the temp a little bit to squeeze some more performance out of it? 

 

Thank you for the help.

Literally just go into afterburner and set all power limit sliders to the right, gpus usually dont have much adjustment anyways so itll be fine, if your gpu does have a crap ton of adjustment then ocp will save you

Well i highered my power limit by 10%. Same issue still running at 60C at the exact same fan speed. Before the main PrefCap Reason was PWR with it sometimes suggesting VRL to be an issue but now the new MAIN issue is VRL. Seems as an normal issue.

Do you need more performance? In general, the cooler a device is, the less power it requires, but unless you're going below ambient, the difference will be very small. If you need more performance, you can increase the power limit in Afterburner by a small amount. If you want to go further, you either need a modified BIOS, which is very hard to do, or a shunt mod that tricks the card into thinking it's using less power than it actually is, thus not correctly calculating the limit.

VRL is voltage reliability, so now you reached the point where the MOSFETs can't keep the voltage stable enough because they're not specced for this much power. Basically your engine is burning fuel faster than the fuel pump can pump it. You can try undervolting, that might help taking some stress off the VRMs, but overall that's just the max all the components on your GPU are made for.

With RDR 2 I never got past 96% at 1080p or 1440p but did at 4k. 

Also the game is CPU bound at 1080p.

Looks like this. As you can see not much difference between 1080p and 1440p. This is with a RTX 2080 ti and an i7 8086k at 5.1ghz all cores.

With my 5900x and 3080 ti I am down to 51% usage at 1080p.  This is with Hardware Unboxed settings. Even GTA 5 is like this so it is a Rockstar thing.

Thank you for posting, i did my benchmark at 1080p.

Okay, thank you for all the help again. Little too scared to try the modified bios out.

Cant you just solder on more caps? Maybe soldering some more caps at the back of the card can help
