I bought an MWE Bronze V2 650W on the 30th of December for my new build (RTX 2060, i5-9400f). I didn't have many choices, the PSU market here is very limited. A few days later I realised that I could buy a Riotoro Enigma G2 for 17 euro more (good job, me!). Furthermore, this PSU makes a quiet high pitched noise when the PC is off. I'm kind of stuck right now, as the consumer protection laws in my country don't allow me to return a product just because I don't like it, so if I would like my money back, I would need to send it in for testing, which can take up to a week or more... I really don't know what to do. Any advice would be much appreciated. (and the cherry on top is this low-load ripple issue. Great.)
