Someplace around this forum is a listing of PSUs, and Sharkoon is on Tier 5....definitely in the junk category, but there are a sprinkling of reviews and evaluations on the I'net that essentially agree on that point. (Never trust just one source.)
For the time being, you can't go wrong with a Seasonic PSU in the higher power category; however, companies rise to prominence, then they subside. Sometimes it takes a sale, or a key leader leaves the firm, then things go downhill slowly.
So, always critically assess anything you are considering for a build, and remember that the leader today will be supplanted by somebody else tomorrow.
