I'm looking for the best power supply units (PSUs) available for around €200. My main priorities are that it should be silent and long-lasting. Previously, I used a Seasonic Vertex PX-850 ATX 3.0, which unfortunately started failing during low power tasks after just one year. It was excellent and quiet in hybrid mode, but its quick failure is disappointing, especially since my last Seasonic lasted a full decade. Maybe I was unlucky, but I've heard there could be some low power issues with ATX 3.0 units.

I'd recommend the Corsair RM850x—it's a solid choice and likely to last a long time. I feel confident it will outlive me!
I've been using the 'be quiet! Pure Power 12M - 1000W' since early 2023 and I really recommend it! It's pretty silent and has been reliable so far. You might want to look into the latest models, just in case there's a newer version available.
I just found out they have a Dark Power 14 model with a 0rpm mode. I'm tempted to try the be quiet! brand since the price for an 850W is similar to my failed Seasonic. Plus, going for 1000W could make it more future-proof.
For sure check out models like the RM850 and Sama XP. The Black Diamond and Cor Reactor are also great alternatives you might want to consider.

I think it's a bit overpriced. There are better options out there for the price.
