INTRODUCTION

   Professionals, enthusiasts and even gamers who spend much for a new PC (or even to upgrade an older one) know all too well the benefits of using a top-tier power supply units. Not everyone however belongs in those 3 consumer categories and so regular users have neither the need or will to spend as much on that specific hardware component and so most of the time they decide based on price alone. Still even though it's clear to everyone that price matters a lot a good price/performance ratio is the best outcome and, in a market, flooded with power supply units finding the right one might not be the easiest thing. Well, it just so happens that Sharkoon seems to have just the answer in their inventory so today I’ll be testing their Silent Storm Cool Zero 850W power supply unit.

   Since 2003, Sharkoon has been developing “Designed in Germany” gaming products, which are popular in the worldwide gaming community due to an exceptional combination of high-performance and affordability. Stylish PC cases, precision keyboards or mice and comfortable gaming chairs – all these represent an elegant blend of high-quality design and modern technology. Numerous awards from the international trade press underscore the performance and quality of the Sharkoon brand.

   The Silent Storm Cool Zero line of power supply units has been around since 2019 (i imagine some tiny improvements have been made since) and is currently available in 650/750/850W outputs all of which feature fully modular designs (future-proof since you can always change the cables if needed) and the 80 Plus Gold certification (over 90% electrical efficiency). The Silent Storm Cool Zero line is based on a DC-DC design/topology (with LLC resonant converter technology) which aside its 80 Plus Gold efficiency also gives the unit a strong +12V rail (70.A) capable of delivering 100% of the units total power output (850W) and a peak power output of no less than 988W. Of course, Sharkoon equips the Silent Storm Cool Zero line with sleeved and slim cables, 135mm fluid-dynamic bearing fan, long-lasting Japanese capacitors certified for use up to 105 degrees Celsius, zero fan and fan delay modes (rear switches) and a full array of electrical protections including over-current (OCP), over-voltage (OVP), under-voltage (UVP), short-circuit (SCP), over-temperature (OTP) and over-power (OPP). In terms of warranty Sharkoon covers their entire Silent Storm Cool Zero line with a 3-year limited one.
