System failure during gameplay occurs.
Hello, Your computer frequently shuts down during gaming sessions, especially when playing Overwatch or Rainbow 6. I’m not sure what’s causing the issue. You’ve increased the fan speeds on your GPU and CPU to manage heat, but it’s unclear if that’s the root cause. Upgrading your power supply might be necessary, though I’m not certain. Your system specs include an i7 9700K, EVGA RTX 3080, Gigabyte Z390, 32GB Corsair DDR4, 650W 80+ Gold.
You're hoping for a crystal ball to understand what's troubling you. The discussion provided questions and resources to help uncover solutions, making the answers straightforward. Yet, if you're not interested in resolving your concerns, then asking isn't necessary.
I noticed a 650 watt power supply paired with a 3080. Have you verified the voltages your graphics card and processor are consuming? Intel and Nvidia tools should display the current power draw, as an older supply might not deliver the full 650 watts. Many of my Dell systems won’t boot or freeze because their 300 watt supplies drop to around 270.
During the test GPU reached 338 watts and the CPU hit 79 watts.
It's your PSU, straightforward. Get a Corsair RMax 850W. If you still face problems, upgrading the PSU is necessary because it's too weak for a 3080K. How do you assess this? Maybe look up information or ask more questions. Your PSU is significantly underpowered—especially for handling transient spikes, which you can't reliably measure. PS: Also, JFYI, the CPU will likely shut down during gaming, especially since it runs on a low-end board. That's not ideal, but Intel 9th-gen CPUs aren't known for longevity. TL;DR: weak PSU causes shutdowns, poor transient handling, so upgrade to a better one (over 2 years old).
I understand NVIDIA suggested a 750 watt power supply for the 3080. To check your actual output, you need a smart PSU with USB and monitoring tools or a power tester. This helps verify your remaining capacity and prevents crashes from overheating components like fans, RAM, drives, and more.

I used OCCT to assess power usage of the CPU and GPU, though I wasn’t sure about its precision. When I got the 3080, it indicated a minimum of 650 watts, but I realized an upgrade might be necessary. The power supply is around three years old, so it may not be operating at full capacity. I swapped it with a NZXT 850 watt unit and will keep tracking any problems.
