Life Span & Safety Features

The Glacier 850 boasts over 100,000 hours mean time between failures (MTBF), indicative of longer device life, better reliability and decreased component failure rate. Additionally, Short-Circuit, Over-Temperature, -Current, -Voltage and -Power and Under-Voltage Protection provide maximum safety to your critical system components.

TUV Rheinland, CE and FCC certification badges


Glacier PSUs have successfully passed safety and compliance tests from CE, FCC, TUV, and cTUVus.

Fan Performance Activity Graph

Silent & Intelligent Fan

Equipped with an Aero-Diversion fan featuring Auto Fan Speed Control, the power supply's 135mm fan turns slowly at low temperatures, reducing power consumption and fan noise to near silence. When temperatures increase, fan speed will also increase. This decreases the odds of over-heating, extends the fan's life span and reduces energy consumption.

Semi-Modular Ports on the Back of the Rosewill Glacier Series Power Supply


A semi-modular PSU design comes with only the essential cables pre-attached. This allows for some customization of additional cables, plus reduced clutter and better airflow compared to non-modular PSUs within your computer case or system.
