Hi everyone, I have a question about my PSU. After checking the numbers from HWinfo, I saw something unusual—the 12V+ supply to the GPU seems fine until I found the "GPU Rail Voltages" at 10.515V. Everything else is at or above 12V. Could this affect performance during gaming?
Have you checked the voltage with a multimeter and tested the 12v leads on the Molex/SATA connectors? What other voltages are present? EVGA offers several PSUs in their Supernova lineup—what model do you own, and how recent is it?
Using a multi-meter feels a bit like voodoo to me, though I think I could manage it. The specifications are as follows: CPU – Ryzen R9 3900X, Cooler – Stock Wraith Prism, Motherboard – MSI Tomahawk B450 Max, RAM – G.Skill Trident Z 32GB, SSD – Crucial P1 1TB, HDD – Seagate Barracuda 2TB, GPU – Colorful RTX 3080 iGame Advanced OC, Power Supply – Evga 750w G+ Supernova fully modular, Case – Thermaltake View 32 TG, Operating System – Windows 11, Monitor – Gigabyte M27Q 170Hz 1440p. BIOS status is unknown at the moment. The system is four years old. The HWinfo label "GPU 12V rail" might be misleading. As you mentioned, the real issue lies in testing with a meter, not just sensors. I'm trying to figure out why my setup crashes during games like Cyberpunk 2077 and BeamNG.drive. It seems like a coincidence that everything started acting up after updating to Windows 11.
