@kiriakost hello again, I know this is an off-topic question but I really want to know what makes the difference between the brands?they use the same capacitor, same PCB, same transformer etc.. which component is the reason to be called premium?
This question has an very easy answer, the electricians engineers working for Seasonic they worth more, than few bits of electronic components.
I know, because I did talk with them too.
The leading design at high electrical efficiency, this period of time it is Seasonic work.
Platinum series they operate much cooler at 50% load when gaming.
At summer time (35C in door) all PSU they release heat waves within your living room.
My very aged PSU this releases 55~58C of hot air stream in a room with 35C all ready, the Air-condition unit, this should now work harder to reduce room temperature.
Energy savings comes mostly from a PSU, this having lesser thermal signature when operates at 35C in door.
All new FANLESS Seasonic PSU taking advantage of newest lesser thermal signature, electronics does not run warm, DC fans does not needed.
This is my sort answer, at my product review I will explain more.
We have now fresh EU regulations about the computer PSU and of new changes in the industry and in the market about assembled new PC and Servers.
Minimum PSU efficiency and power factor requirements from 1 January 2023
