I'm feeling a bit overwhelmed by the Power Supply Unit (PSU) tier lists I see online, especially regarding some technical terms. For instance, I don't know what 'minor rails' are or what it means if they need tuning or if their protection settings are set too high. Also, I'm unclear about 'ripple' and how important it is to have it suppressed. Then there's the whole idea of 'semi-digital' PSUs – is that a good or bad feature? Lastly, I'm not sure if a fan with a custom rifle bearing is significantly worse than one with a fluid dynamic or maglev bearing.
I recently upgraded my graphics card to a 5060 Ti from a 1080, but I'm concerned about my current PSU, which might be over a decade old. I want to ensure it's safe to use with my new setup. How do I sift through all this information to decide if a PSU is reliable enough or if I might be risking my new GPU for a lower price?
You can see my current build here: [PCPartPicker Build](https://pcpartpicker.com/list/gVM6cx) and here's the GPU I purchased: [ZOTAC 5060 Ti](https://www.microcenter.com/product/694730/zotac-nvidia-geforce-rtx-5060-ti-twin-edge-dual-fan-16gb-gddr7-pcie-50-graphics-card).

Minor rails refer to any voltage lines besides the crucial 12V rail, which powers your CPU and GPU. So, things like the 5V and 3.3V rail are considered minor. As for ripple, it measures how much the voltage fluctuates; ideally, you'd want it to be minimal to keep your system stable.
Semi-digital PSUs are just a style of AC to DC conversion—nothing to stress about. Regarding fans, their construction doesn’t hugely impact performance, so you’ll be fine with B-rated or higher PSUs generally. If you're really curious, you can find reviews of specific models, but it might not be necessary.
Thanks for clarifying! So, it sounds like even if a PSU has a B rating but notes about potential tuning issues, that’s still likely okay?
