Wow, all of 2 reviews.  Were they by technically expertise sites
reviewing PSUs?  Or just some users reporting in less than a month that
what they got worked at that time in a hardware configuration they never
stated?  An example of a more technical review is shown at:

At full load rating, 12V was just under the ATX spec.  At 110% load, the
PSU failed on 12V to meet the ATX spec.  Unfortunately many PSUs are not
overbuilt.  This reviewer didn't do sustained load testing to ensure the
PSU didn't burn up.

At 45 euro, you really think the warranty means anything?  It'll cost
you that, and probably a lot more, to ship the PSU back to Sparkoon,
plus the downtime.

80 Plus Bronze is not a great spec for a PSU.  OEMs are allowed to skew
the testing by letting them hand pick which units to test, and the spec
omits several key tests.

The less efficient the PSU, the more it has to dissipate for the same
load as a more efficient PSU.  Of course, with more efficiency comes a
higher price tag.  A hot PSU won't last as long.

Along with lower efficiency, and not knowing who really made (the OEM)
of the Sharkoon-branded PSU, is why I suggested running at a max load of
70% of the ratings on the sticker on the PSU case.

Not saying what you bought is bad nor saying it is great.  With a
"Sharkoon" sticker on the inside, you don't know which OEM is inside.
You may not need to dismantle the PSU to check the OEM.  Use a
flashlight to peek through the fan and venting grills.  I could've
missed it at their web site, but didn't find anything there noting the
terms of their warranties.  I did find:

With Sharkoon promoting themselves as a gamer's brand, the PSU you got
might be okay, but 80 Plus Bronze is at the bottom of that spec.
