Fairly New PSU is hella loud

Okay, so I'd say about less than half a year ago I got a 500W evga PSU... I've always noticed how loud my PC was, but I just recently felt like doing something about it. It's 100% coming from the psu.. I have it in the case correctly, it's not fixable in the bios, and nvidia 3d settings aren't doing much either.
Now, it sounds like the things going into hyperdrive which is what confuses me the most. I have an Intel i5, 3.1 ghz, 8g ram, a GTX 730 (the 60 dollar kind lol) so it's not like it needs a lot of wattage to keep up (I bought the 500w with plans to get a better gpu, but money was stolen from me)

What might help is the mobo I'm using is pretty outdated. I honestly have no idea what type it is. The thing is still green and I have done as much research as possible on it, but nothing comes up.. it came with a prebuilt manufactured 5 yrs ago... Could it be the motherboard causing this? Or is the psu just crapped out from the start? I can answer any questions to help

Lower-end PSUs usually have sleeve bearing fans in them without any passive features. Meaning that the fan turns all the time and due to the design of sleeve bearing, the fan lifespan is also very short (20.000 hours or so) where when the fan is at the end of it's life, it will get noisier. Higher-end PSUs usually have fluid-dynamic bearing fan in them which is very quiet with long lifespan (300.000 hours or so) and many such PSUs also have passive fan where the fan doesn't turn at all when there's a low load on a PSU. E.g Seasonic Focus+ series,
