Seasonic is one of the best power supply manufacturers out there and often makes power supplies for other companies which then simply put their own brand on them.
The specific one I got (G12-GC-650) is quite silent and has its cables relatively well organized.
With this, I replaced my old power supply which, due to its age and usage (at least 15 hours a day), had started to reach the end of its life, mainly because its capacitors had "aged".

Very good and reliable PSU. Quite good in terms of performance / consumption ratio and excellent for its price.

I do not have specialized knowledge to evaluate its construction quality, but I have set up 3 systems with this one. It is quiet and functional.

Purchased for 120€ in the summer of 2020.
Spent the whole of 2021 mining with 2 graphics cards 24/7.
Now, it plays games but not fanatically, when time allows.....
So far, I have not had any problems.
I am not an electrician, of course, but this company has the best reviews.

26/02/24: Still working perfectly.

It is one of the best PSUs available at this price, it really deserves its money even though it is not full modular or semi, it has very long cables and you can easily do cable management

I mainly bought it for a Plex server (low-mid range system). It has plenty of SATA and molex connectors so you can connect multiple hard drives. The power supply is quiet (at least for me). In terms of wattage, it's okay, I didn't need a lot of watts anyway. It's gold certified and it's from Seasonic, which we all know is one of the top manufacturers. It's Tier B according to forums. So it's one of the best purchases I've made.
