PC performance issues during gaming and frequent crashes are occurring.
PC performance issues during gaming and frequent crashes are occurring.
My computer has been struggling heavily during gameplay, shutting down completely after prolonged use. It performed adequately for a short period after setup, but then began to fail severely, causing crashes and drastically reducing frame rates. I ran several benchmarks on all my hardware, and temperatures remained normal. I returned the GPU motherboard, CPU cooler, and power supply, but they insisted everything was fine. All drivers are up to date, and I’ve reinstalled Windows multiple times through USB. Previously, I averaged around 400 FPS in a game, now it’s only about 140 FPS. I’ve searched extensively for possible issues over the past two years without finding a solution. No one has been able to assist effectively. I’m exhausted and just want my system to function properly. Do you have experience and can you help? Please message me on Discord or Telegram, or reply in this thread. I can share some benchmark results for my GPU and CPU if you’d like. I’ve also tried other games, but they performed worse than others. My system has fluctuated between stable and unstable performance. What could be causing this problem?
The Corsair RM-series power supply is of average quality. It isn’t the worst, but it’s also not the best. This suggests the problem might lie with the PSU itself or could be elsewhere. The only sure way to confirm is by testing it with a higher-quality unit.
Running an RTX 3080 on an 850W unit can be challenging because of temporary power spikes from the GPU. These spikes are 2 to 2.5 times the GPU’s TDP. For the RTX 3080, which draws 320W, you’d need either a 1000W ATX PSU or a 850W ATX PSU. This extra capacity helps absorb those temporary spikes. Before using an ATX 3.0 PSU, it should have enough wattage to handle the fluctuations. Post-ATX 3.0 models are designed to output double their rated power briefly, allowing them to soak up these spikes.
What are GPU transient power spikes? You can watch a video for more details: https://www.youtube.com/watch?v=wnRyyCsuHFQ
Good 1kW PSUs suitable options include Seasonic Focus/Vertex/PRIME, Corsair RMx/RMi/HXi/AXi, and Super Flower Leadex Gold/Platinum/Titanium.

The first step should be to replace with a new, reliable PSU that can manage these spikes. If the issue persists after that, you can proceed with further troubleshooting using the remaining components.
Random reboots and shutdowns are mainly due to two factors:
1. The CPU or GPU overheats, triggering the system to shut down to avoid damage.
2. The power supply fails to provide sufficient power to the GPU or maintains unstable voltage for the PC.
If temperature was the problem, it might have been because the room was warmer at that time, causing the CPU or GPU to slow down and shut down. However, a failing PSU is more likely, especially since an 850W unit isn’t adequate for an RTX 3080.
Basic calculations show: a 320W GPU can jump to 640W–800W. The CPU uses about 105W (higher if overclocked). Adding the rest of the system at roughly 100W, you’re looking at combined spikes around 840W–1000W. An 850W unit can handle up to 840W temporarily, but not sustained loads beyond that. A 1kW PSU can manage up to 1kW for short bursts, making an 850W ATX 3.0/3.1 suitable for brief periods.
Low FPS could stem from GPU drivers, CPU issues (like PB2 or PBO values), or the PSU’s high ripple. Therefore, replacing a new, quality PSU is advisable—it addresses many of these concerns and resolves shutdowns.
Please check a better PSU with more power. I need to mention that my room gets very hot and everyone says it stays warm, even though I don’t see the temperatures rising much. The main issue is frame rate, I’ve updated drivers for both GPU and CPU, but nothing seems to help. Also, I’m confused about why the benchmarks seem okay unless they’re actually lagging.
It varies based on the benchmark you choose. Cinebench for CPU performs well (Prime95 and AIDA64 also do), while Superposition works better for GPU. The 1080p Extreme preset is effective as it simulates a tough test. You can try different presets and compare scores with other GPUs to assess average performance. RAM testing via memtest86 is recommended, with 4 passes (15 tests per pass) being standard; however, 32GB takes about 5 hours per pass and 20 hours for four passes.
I shared two screenshots in my thread with the results you can check. I used four sticks of 8 gigabytes of RAM, did a bench test similar to what you'd see on BIOS, and three passed. I had to stop before the last one, but now I only have two left.
I've already looked at those, that's how i knew that you already ran Cinebench. Though, you only did multi-core test. No test for single-core and GPU.
But multi-core result looks good.
E.g here's similar setup with R9 5900X and RTX 3080,

With a diff that this person OC'd their chip to get a bit better multi-core result than you did.
As for 3DMark, well, your GPU performs average,

"or something" is very vague. With PCs, you need to be precise on what troubleshooting steps you actually did and what the result was.
Memtest86 does launch outside of Win as well, but it doesn't test one DIMM after another, instead it tests all DIMMs at once. And in one full pass, there are 15 tests in total, that takes some time. For 2x 8GB, you're looking ~2.5h per one pass or ~10h for 4 passes.
Memtest86 is only way to know, if RAM works as it is supposed to.
Here is full rundown what each and every test in memtest86 does,

For absolute result, 32 full passes are needed. Since Test #7 needs 32 passes for it to check every possible option. But no-one in their right mind is going to do 32 full passes, since it takes forever + then some. (For 2x 8GB, ~80h for 32 passes.)
1 full pass is bare minimum. 2 full passes is better, while 4 full passes is considered acceptable when testing RAM. Since RAM testing takes a lot of time, best to let it run overnight (when you're sleeping).
