The Inter-Tech IPC ASPOWER R2A-DV0800-N PC power supply provides a stable power supply for server configurations and systems that require continuous operation. Its redundant design consists of two separate modules that take over the load in the event that one of them fails. With a total output of 800W and an 80 PLUS Platinum certification, the power supply operates with high energy efficiency, reducing both running costs and residual heat production. The compact 2U format installs into server racks.
When choosing a suitable PC power supply, the key parameter besides the format is its power output. This indicates the maximum number of watts the power supply can continuously provide to the components in the computer. It's a good idea to use a web calculator to work out the optimal power output based on your chosen components.
The foundation of this power supply's reliability is its redundant architecture. Inside the chassis, there are two separate, independently operating power supply modules. If one module fails, the other immediately and seamlessly takes over the full load, keeping the powered system running. This concept is crucial for servers, data storage, and other critical applications where any downtime is undesirable.
Energy efficiency is confirmed by the 80 PLUS Platinum certification. The power supply converts a high percentage of mains electricity into usable energy for the components, reducing losses in the form of heat. Two 40mm fans with automatic speed control handle the dissipation of residual heat. They adapt the speed of the cooling to the current load and temperature for an optimal balance between noise and cooling performance. A set of safety circuits protects the connected hardware. This includes protection against overvoltage, overcurrent, short circuits, overheating, and overload.
The power supply offers extended status monitoring options via an integrated I²C bus. Thanks to its compatibility with the PMBus protocol, administrators can monitor key operating parameters such as voltages, currents, temperatures, or fan speeds. A status LED display provides a quick visual check, and if a problem is detected, the system activates both an audible and visual alarm.
The 80 PLUS certification was created to objectively assess the efficiency of PC power supplies. This gives users a simple and clear way to compare different models. In the European market (where 230V is used), there are six levels of 80 PLUS certification with set requirements for PC power supplies. Higher energy efficiency primarily means lower energy consumption.
