i can easily say you what i mean:
my GPU cloking max 2 Ghz instead of 2,8.
i locked my FPS on 50 with frame gen enabled so in this game my GPU draws on average 150 Watt. I tested it and i watched over the time Period on the numbers.
Every time ppl want to tell me, that my PSU must be the culprit there and even then my GPU can Draw 320 Watts on other games + my CPU maxes out and i got no shutdown.
I Play Unreal V titles. ARK Survival Ascended is an exampel of a Game thats poorly optimizes and draws Power like no other has seen before. T got way less FPS then here and it draws way more Power. I Played it at the time it came out. No Shutdown. 320 Watts drawn here, 90 Watts on the CPU etc.
X-Box One
650 Gold means it can deliver 650 watts while drawing 11% more power out of the wall. this is the efficency. At least here in the EU it is required that the PSU can deliver what is marketed...
In my case, with the 25.3.1 AMD drivers and Highest textures and the game installed on a SATA SSD, I got system freezes and restarts, but when I changed the first two parameters the restarts changed to GPU driver crashes, and then moving the install location to a NVMe SSD seems to have fixed the issues entirely. My current impression is that something can go wrong with the directstorage data loading and cause the driver to hang and timeout. Which might be possible to work around by changing the driver timeout delay in the registry, but I didn't try that.
But one thing to keep in mind is that software monitoring in Addrenalin or other software is only reading the wattage at the core or input on the GPU (what is "given" to the GPU).
But the actual draw can be much higher depending on the efficiency of the parts used, the temperature, and even humidity.
Even if it said 320W in software, that's after any loss of power that may have have to do with conversion or step up/step down, and that amount is around 5-15%. It could be more depending on how motherboard makers handle their power circuitry.
And, what do you know...let's look at what MSI a motherboard manufacturer reccomends for PSUs:
https://download-2.msi.com/archive/mnu_exe/pdf/RECOMMENDED_PSU_TABLE.pdf
Here, 7900XT + AMD R7 CPU is actually recommended an 850W PSU. These numbers aren't coming from anywhere, it's coming from actual testing.
AMD themselves:
Note the bold about 12V 64A... does your PSU meet that? Unlikely.
hey,
in theory your completly right.
But you missed the point pretty hard. My Graphics Card has no problem. i only and only got the shutdown in Wilds.
What you describe is the electrical law behind it. This law stays the same no matter which game i play. So i need to have shutdowns with every other game. period.
ARK ASA: 900 hours not a single shutdown with this GPU and my 650 Watts Power supply. Not a single time i got a shutdown while drawing 320 Watts + Power with the GPU alone.
Can you explain this?
Destiny 2 (Unlimited frames): 300 Watts Power draw, 1300 hours game time, not a single shutdown. per electrical law of Watt it needs to shutdown if my powerdraw is higher than my PSU can deliver. it doesnt.
Wilds: around 70 hours, 10 shutdowns: around 150 Watts Powerdraw cause of highly limiting the GPU in Drivers and in game with locked frame rates.
Every Powerdraw i called was looked through adrenalin. So on every game i called so far your 5 to 15% extra power draw applies.
secondly: a Technician named Igors Lab has allready shown that the recommended PSU Specs are way to high compared what is needed. 90% of the time you can go 100 watts less and you will not suffer any shutdowns.
So no, they dont test much, they try to upsell as much as they can.
It's not an upsell, and even if IgorsLab or whoever tests it there's an issue: PCs vary dramatically in how they are configured. AMD themselves recommend that value of 750W (12V * 62A + safety margin) because they designed it to be so. Also keep in mind that's the minimum recommendation .
Also, 62A is for the GPU clocked at its base game clock around ~2000MHz, not for an overclocked one
Thing is, consumption of power can vary on literally anything. consumption also varies on work done, not just clock speed
# of harddrives, whether your board supports USB PD and you are using, case fans, lighting, etc. but not just what is connected, the condition and age of components matters too .
Again, as heat rises, the power draw also increases for most electric components...and increases heat and power draw even more.
Now, back to the 62A , what happens when your PSU needs to supply 62A on the 12V rail but can only supply less than 54A, before accounting for CPU and anything else you have attached?
Motherboards are designed to shut the computer off when they detect voltage drop that look abnormal. PSUs also are designed to shut off. I assume you are experiencing this if your PC literally turns off -- that's only done by the motherboard or PSU in most cases, rarely ever will the CPU shut the PC off like that unless it was overheating or it also has an electrical problem detected
Now, as for why this game only does it -- I don't know, no one can guess how components interact which is why the specs exist in the first place -- they also give space for the unexpected.
hey thanks for the answer
yes you are right again. all the theoretical and pratical stuff is right. This is why i reduced the clock speed AND the work done.
idk where your 62 amps comes from tbh. For 62 Watts on 12 Volts to occure you need a power draw of 744 Watts. OfC the PSU cant deliver this power draw but first of all the power must be drawn.
Dont expect that 62 amps flowing through the PSU all the time. It draws the Power it needs. So you have to add all power drawing ressources in your PC:
GPU: 315 Watts overhead 100 Watts so 415 Watts.
CPU: 120 Watts (never saw 120 watts only 100 Watts) no overhead
RAM: Let us say it costs 30 watts (what is pretty much)
Storage: 27 ( 2 ssds + 1 hdd max output per specshiet)
Fans: 15 Watts ( 8 cpu fans 1,8 Watt per fan as of the specshiet)
Mobo: 30 watts
peripherals: 1 Watt
and now if we add it aaal together we see what we have without overhead and what we have with overhead als power draw:
without overhead: 538 Watts
With overhead : 638 Watts.
Powersupplies have to deliver the ammount its marketed for. So it draws more according to the efficiency.
i went extra with the highest Power draws i could think of which is even now covered by my PSU with the typical overhead you should have for your GPU.
638 watts divided by 12 volt = 53,17 Ampere and that lies within specs.
and now you see how much they want you to have more which is not needed.
Actually, looking into it, your SSD might need a firmware update to get directstorage to work correctly? Seagate has an article entitled "How To Update Your DirectStorage Firmware for FireCuda 530", which gives instructions.
hey, thanks for the feedback.
i tested lower textures, i tested without frame gen and FSR and without raytracing. the only thing that helped for a time was deinstalling and reinstalling the game + deleting shardercache. Was able to play around 30 or 40 hours error free.
and then it happened again.
direct storage isnt active on win 10 if a remember correct.
... well i think then its time for switching to win 11. Thanks for the feedback.
If you don't mind updating to Win11 then hopefully that fixes things for you. If not... I didn't see mention of which driver versions you've been testing with, so maybe that remains an option.
