Sharkoon SilentStorm Cool Zero 850W 80+ Gold PSU Review

The package and its contents

The package is a typical size for an ATX PSU. The 850W unit is well-protected, and nothing is too tight as we used to see in other PSUs. The PSU is additionally covered in the pouch, while cables have a separate bag.

The package includes a power supply, modular cables, a user manual, screws, and a power cord. Simply, everything we need for the installation.

The package is well described, and we can find nearly full specifications printed on the outside. The PSU specifications are on both the box and the PSU itself.

The design is quite interesting and will look well on a high-end PC. All cables are modular, so we can limit them to the required minimum, saving space and improving airflow.

On the back, we will find two switches that most brands are not using. One is called Fan Delay Mode. It keeps the fan spinning for about a minute after turning off the PC. This is what some top PSU series have as a standard option, and we can’t turn it off. We recommend turning it on as it helps keep some components safe. As we can notice, it takes up to about a minute until the higher wattage PSUs power down completely. At this time, some elements can still be hot.

The second switch is Zero RPM Fan Mode which enables semi-passive mode. When the PSU isn’t under load, then the fan won’t spin. It affects the potential noise (which in this case isn’t audible) and helps keep the PSU clean as it won’t gather dust.

All the cables are long and flat what helps in installation and optimal airflow. I wish to see all cables separately braided, but it could be costly and not really required for most users. It still would highlight the high quality of the product.

On the next page, we will take a closer look at the PSU and its performance.
