What is Expected Behavior of GPU Voltage and PCIe Voltage? [HELP]

[LeSandwich]

under load, or depending on the voltage spike, I see drops in the PCIe +12v Voltage readings on both HWInfo and GPU-Z softwares. the drops I see are still in ATX spec and if I'm not mistaken, higher load on the GPU can draw more power from the PSU and generate drops in the PCIe/12v rail, but what is the expected behavior here?

at 0.6 and 0.7v on the Core GPU Voltage, I see 12.0v on the PCIe reading
once I hit 0.8 and 0.9v, the PCIe drops to 11.9
and if I hit 1v, the PCIe drops to 11.87/11.88

under normal gaming load, I'm usually seeing 0.7-0.9v readings, although sometimes it might quickly spike to 1.08v; furthermore, if I run Heaven Benchmark at full 100% GPU load (around 230-250w iirc for RTX 3070), my PCIe voltage drops to ~11.79


is this normal behavior for the PCIe and Core Voltages? I know higher loads can create a drop in the PCIe, but are these specific voltage readings okay? my PSU is a Phanteks Revolt 1000w so obviously it can handle the 3070, I just need to know if something seems faulty here

There is no expected behavior, except that the voltage doesn't drop below the ATX spec which is 11.4 volts. You're literally talking about less than 1% offset and asking if its faulty. Go back to playing minecraft, or fortnite, or whatever you kids these days play. Bruhh

lmao Elden Ring but close enough I guess

wouldn't necessarily be keen on the voltages going too close to the ATX spec limits and that's why I wanted to know if I SHOULD be seeing those offsets. which apparently I am so whatever
