It's a piece of crap (big crap)
Power supply bought in July 2017 and died in November 2019, i.e. a lifespan of two years and four months: record broken!!!
(small precision: it had to run on average 3 hours per day)
On the power supply it is marked texto "PRODUCT CONCEPTION, DESIGN AND QUALITY CONTROL IN GERMANY" good after it is not necessary to joke it is nevertheless of made in china.
I'm not going to write more about it, I've had power supplies for less than 50 quid that have lived in much worse conditions and much longer, so if you want to spend 200 quid on a power supply and have a chance to change it in two years just after the warranty expires this product is for you, otherwise you can look at another brand.
