Seasonic S12II-620

So I have the AC adapter because my old Bequiet with 530 watts (Cable Management) at my computer,
{
AMD FX8350
MSI 7870 Hawk
GA 970A UD3
Drives Samsung SSD and 2 Seagate
Couple fan yet
}
has begun unpleasantly high frequency buzzing about.

The Seasonic running stable so far and I have about 2 months.
The voltage values ​​are stable.
At full load, it goes into the 12 volt rail max. to 11.8 V, I think ... read with AIDA64.
These are quite good results for my health,
I've seen much larger declines in power supplies that have even more watts. (With ählichen components)

Contraindications to the power supply, the plug and the fan
Unfortunately, a SATA power connector is broken in me, one half is canceled by the plug.
And I did because now I really do not apply force.
But there are enough connections, so this is a, not a real loss.

When fan I had wondered after few hours Far Cry 3 a flutter-like noise,
by Google search, I learned that it was normal for the power supply and no reason for concern is.
The sound I've also heard only once.

Everything else looks as far from tidy and I can really recommend it.
I have a price of 79 euros paid ... Let's see what it looks like in the distant future.
