At the jonnyguru link, they say "the results of the Chieftec are little bit worse as from the Kolink".
I have the Chieftec they are talking about, the SFX-350BS, and it is great. Cheap yet efficient, quiet yet cool, stable (no problems whatsoever for the past few years). It's currently powering an i3-6100 on a Gigabyte GA-B150N Phoenix, 16GB RAM, 500GB M.2 Samsung, and an EVGA 1060 3GB. During maxed out FULL HD gaming (Witcher 3, Call of Duty Black Ops 3, GTA V so far) the system draws 130-150W from the wall. As you can read on the russian review linked from jonnyguru, in this range the PSU is above 90% efficiency and as quiet as a mouse. What more could I ask for? And as I have accidentally found out a few day ago, there seems to be a more powerfull version, too:

Anyway, if Chieftec's results are a little bit worse than Kolink's, I see no reason not to buy the Kolink PSU... for the right hardware, obviously.
