Most games are slow when things go wrong, especially when stuttering makes frames per second drop low.

I have had really bad stuttering and frame rate drops in most games for a long time. It goes from 100-140 frames down to maybe 20-40, then it comes back up all by itself. I have a computer that is strong enough to play these games, which is an Intel i7 10700K with a NVIDIA RTX 3080 and 32 gigabytes of RAM. I tried uninstalling the graphics drivers and updating them again, changed settings in the NVIDIA control panel many times, tested every Windows option, checked power management settings, adjusted CPU settings, etc., even uninstalling Windows completely and updating my BIOS. Nothing really helped much. My temperatures look fine to me; after all this trying, what stands out to me is that my graphics cards are not being used very well in some games, and I see huge drops in both the CPU and GPU usage right when I get these stuttery moments. I tried several different GPUs, lots of RAM, changed many settings, but nothing has fixed it yet. Any advice would be great. EDIT: These problems happen mostly in tougher or less optimized games, even though my hardware is good for them. I can play simpler ones like Valorant and CSGO without issues.

Which make, brand, and specific model number (SKU) do you have for your power supply or PS U?
Alright, that's a budget PSU from EVGA. Not the very best, but not THAT bad either (though, others can correct me if I'm wrong). EVGA released the BR series for the budget-conscious users. Actually, NVIDIA recommends a min 750 Watts PSU for the RTX 3080 GPU. Your PSU should also work, but for a 750 Watt unit it's much better to grab at least some other high quality unit, min GOLD rated and above. I'm not saying the PSU is indeed the culprit here, but can you test your GPU by using some other high-quality PSU ? Maybe borrow one from your friend, or test your GPU on his system ? BTW, what is the brand and exact model number of your RTX 3080 GPU ? These cards require a single 12-PIN power connector (you can use an adapter), with some models requiring 3 8-PIN PCIe cables. Though, your current PSU is already having 4x 8pin (6+2) cables for the GPU. NVIDIA GeForce RTX 3080 Specs | TechPowerUp GPU Database Since you are getting low GPU utilization only in graphic demanding games, I still suspect your PSU to be the cause of poor performance here. Though, if the game is badly optimized, then that's a game's Engine and coding issue, and not your current hardware. For the RTX 3080 I would personally go for a more powerful and high quality PSU from any reputed brand. Just saying !
Thank you so much for your reply and help. I'm going to try testing with a friend's power supply soon to see if that fixes my problem, then I'll buy a new one. Back when I used a 3060 Ti, I had the same issues, but it could just be a bad PSU (or one that is too old or cheap) all along. My graphics card model is FTW3 ultra gaming with 10GB of GDDR6X memory.
I know it has been a long time since then, but I've swapped out the power supply unit and am still hitting the same big drop in frames per second when usage goes down. I spent hours trying to figure this out by checking for overheating and other problems, but I can't pinpoint exactly what's causing it. Do you have any other ideas besides a bad PSU or thermal issues?
Which power supply unit (PSU) model or brand did you actually purchase and install, not just talk about?
