Hello, everyone. Could you please review my HWiNFO readings about the PCIe slot voltage? I have some concerns about potential dangers if those fluctuations occur during full GPU load. The first image displays GPU data from HWiNFO and GPU-Z, while the second shows the motherboard perspective. I’m unsure which reading—11.6 V or 11.736 V—is more significant. Are these variations normal? Thanks. P.S. Don’t worry about my native language on HWiNFO. My specs are: Motherboard: Gigabyte B85+HD3 Rev 2.0, PSU: Corsair TX650M, RAM: 16 GB, CPU: Intel i7 4790, GPU: Gigabyte RTX 3060 Windforce OC, OS: Windows 10 Pro 64bit.

It's not exactly what we expected, though I think it's still aligned with the requirements. Also, my Z97 configuration behaved similarly.

Sure, to put it simply—if everything holds steady so far, I shouldn't have any concerns, correct?

If it's stable, everything is fine. There’s always a slight voltage drop when drawing power. The spec calls for at least 11.40V. It seems your PSU is providing the correct voltage, but the board’s PCIe power delivery isn’t up to the mark.

Under these conditions, your parts should remain safe over time. No further voltage reduction is expected, so long-term stability is likely maintained.
