I've been looking into the PURE POWER 13 M 850W power supply and I heard that its quality might affect coil whine, though it seems to be an unpredictable issue overall. It received strong ratings on Cybernetics and is listed as an 'A' on SPL's tier list. I'd love to hear from anyone who has experience with it, especially in relation to how it performs with the 9070XT or 5070ti graphics cards.

I think it's all about luck. I have a 9070XT and tried a couple of PSUs; I got medium coil whine with the FSP Hydro G Pro 850w but had no issues with the Hydro Ti Pro 1000w. There's no guaranteed outcome, just a chance.
From what I've seen, it's really hit or miss. Personally, I've paired different PSUs with various GPUs and had differing experiences—like getting medium coil whine with an EVGA 750 Supernova Gen 2 and none with the Gen 3 model. So, it really seems to depend on the combination you have going on.
Coil whine can be pretty random. Some people experience it more than others due to various factors, including the specific components they have. For example, the Corsair RMe series tends to have more issues with coil whine compared to the RMx series. So, it's definitely something to consider based on your setup.
