I5 8600k Voltage Drops

Verify two points:
Observe the CPU GHz during Cinebench, ensure it decreases under maximum GHz.
Check for VRM or Current limiting issues; they will turn yellow.
I followed your advice and the max GHz continued to drop slightly below the limit, but the VRM or Current didn't flash yellow.
Could there be an issue with my PSU: VS 650 (corsair)?
If you observe XTU during the benchmark or review the graph afterward, you can identify what occurs when the GHz drops—it will reveal details such as temperature, current, TDP, etc. It should clearly display the relationship between these factors. For instance, with my EVGA FTW Z370 board, it often sets the BIOs Processor Core IccMax to 120A, which is significantly lower than expected and usually restricts the CPU to around 60W TDP. This issue can be resolved, but only through XTU support. Additionally, not every CPU benchmark or real-world application runs at full capacity. If the workload varies, the GHz and voltage will change accordingly. Cinebench generally utilizes all cores effectively, providing a solid load; I notice you are doing that. The XTU benchmark applies loads with multiple cores, so it doesn’t overburden them much. Here’s a snapshot of my system under an x265 task. For context, my i7-8700k achieved a Cinebench score of 1579 with older 2400-speed RAM, roughly 100 points lower than what review sites report. I recognize that achieving those high scores with mixed components and a preference for consistently high temperatures is challenging.
