I need to replace an ailing PC power and cooling 1KW , Silverstone is a solidly built silent running power supply that would last the average user 3-4 upgrades without a problem.
I wish I could afford one; because Seasonic's quality has been consistent through the years... which is unfortunately more than what I can say about most other OEM brands.
I personally have only 1 Seasonic power supply and that is the SS-350SFE. It has been a great little power supply so far. I feel it has a good build quality to it. After running this power supply in a gaming sfx computer, I can honestly recommend Seasonic now.
Seasonic is my favorite brand of power supplies. They make top quality power supplies that a lot of other vendors use also. Quiet, reliable power supplies with awesome features and warranties.
