Hi everyone

I hope someone can help me. I have the 1000W FSP Hydro Ti Pro 80PLUS Titanium PSU since November 2024. For the last few days I've noticed an odd clicking noise coming from it when playing games (under load). Oddly I've noticed it in just 2 games but its is especially noticeable when playing Cities Skylines 2, the other is GTA 5 in certain scenes. Unsure why is that, I play games in 4K, mas settings etc. It does not appear in any other demanding games so far like Cyberpunk 2077 etc. 

Could someone advise what could be the cause ,if it is a sign of failing unit etc. I did not experience any shut downs, crashes etc. PSU is connected to high quality extension current protection etc. 

Link to my system specs and the YouTube clip with the issue are linked below.

Thanks!
