The MSI PRO AA850PL PCIE5 computer power supply provides a stable electric current to the components in your PC case. This power supply unit delivers a total output of 850W, so it supplies enough power for even the most demanding graphics cards and processors. The power supply's architecture conforms to the ATX format and uses modern power technologies. The fully modular cabling makes arranging the internal case layout easier and helps improve airflow. The design includes a mains switch for quickly disconnecting it from the power grid.
When choosing a suitable PC power supply, power is a key parameter in addition to the format. This indicates the maximum number of watts the power supply can continuously supply to the components in the computer. It is advisable to use a web calculator to determine the optimal power based on your chosen components.
The power supply is 80 PLUS Platinum certified, confirming its high efficiency at various load levels. Efficiency does not drop below 92% during normal operation, which reduces energy loss. Less unused energy is converted into waste heat, which lowers running costs. The electrolytic capacitor, with its high-temperature resistance of 105°C, contributes to long-term voltage stability.
The device supports modern ATX 3.1 and PCIe 5.1 specifications for seamless cooperation with modern components. The power supply can handle short-term power excursions of up to 200%, which prevents system crashes during sudden current spikes. The dedicated 12V-2×6 connector provides power to graphics cards with a capacity of up to 600W. Safely connecting modern graphics cards requires only one special cable.
A comprehensive suite of integrated electronic protections enhances the safety of the entire computer. The power supply includes over-voltage protection (OVP), under-voltage protection (UVP), over-current protection (OCP), and over-power protection (OPP). It also features short-circuit protection (SCP), over-temperature protection (OTP), surge and inrush protection (SIP), and no-load operation protection (NLO). The protection system actively prevents damage to connected components in case of instability in the electrical grid.
A 120mm fan takes care of cooling the internal parts. The fan uses a hydraulic bearing, which reduces friction and noise during operation. Active PFC maintains a stable power factor and contributes to the efficient use of the input AC voltage in the 100–240V range. Flexible cables with an embossed surface make them easier to bend and route behind the motherboard.
The 80 Plus certification was created to objectively evaluate the efficiency of computer power supplies. This gives users a simple and clear way to compare different models. On the European market (where 230V is used), there are six levels of 80 Plus certification with set requirements for computer power supplies. Higher energy efficiency primarily means lower energy consumption.
