Both of these units are good and efficent. Both are around 500w and both are fanless.

my questions goes to the buzzing electrical noise sound. Which one is better ?

I heard that the seasonic are plagged by this buzzing sound. Whether the kingwin / SuperFlower model is not.

No one ?

Really ?

Have experience with two Seasonic X560, where one has a high pitch buzz/whine that changes according to load and another that are effectively silent.

The Super Flower 550 platinum Golden King line has a constant lower frequency buzz than the noisy X560 which makes the Super Flower less intrusive.

Have no experience with the Platinum Seasonic units, but SPCR recently had an experience with one.

maybe the reviewer can give us his experience with the two fanless units.

no electrical noise with my x560.

I have a SuperFlower Golden Silent Fanless in my fileserver. If I put my ear up next to it, I can hear a slight buzz, but it's quiet enough that even from 10cm away it's inaudible.

that's nice to hear...

anyone from seasonic avec the new fanless ones ?

please, no comment about other seasonic psu. only the fanless plantinum ones

What is the correct orientation of Golden Silent in the case with top PSU mount? Should the heatsink be oriented up or down? If mount it with all 4 screws, then the heatsink is turned down.
