I have a Seasonic S12II 520W 80+ Bronze PSU,
My PC specs are: AMD Ryzen 5 2600, AMD RX480 4GB, 16GB DDR4, 1 ssd and 1 hdd.
I want to upgrade to a Seasonic Focus GX-650 650W 80+ Gold PSU, it's the best choice in this price range available in my country.
My reasons for upgrading are future proofing my PC in case I get a better PSU like an RTX 3060 when it releases or something that needs a better PSU, and because I read that my PSU is apperanly very old model (pre-Haswell days) so I would love to have something new and modern, and it's also fully modular which is always nice to have.
I also have random blackscreens and crashes that were never fixed when I changed my old no brand PSU to this seasonic model ( I also changed CPU, MB, RAM ) and the problem persisted especially when I try to OC my GPU, but the problem started occuring much less after cleaning and changing the paste on my GPU.
Anyway is the upgrade worth it? considering I will pay around 50-60$ for it after I sell my current PSU
Edit: My biggest reason for this upgrade isn't the wattage but the new unit being modular and being more modern and efficient in general
