Inter-Tech IPC ASPOWER R1A-KH0400 400W (redundant)
The Inter-Tech IPC ASPOWER R1A-KH0400 redundant PSU supplies power to server assemblies in a compact 1U design where reliability is a key factor. Its design with two independent modules keeps the system running continuously even if one power supply unit fails. A total output of 400W covers the needs of critical applications, while 80 PLUS Silver certification confirms high energy efficiency. A pair of 40mm fans with automatic speed control, which adjusts cooling performance according to the current load, dissipate heat from key components.

Choosing a power supply
When choosing a suitable PC power supply, the key parameter besides the format is the power output. This indicates the maximum number of Watts the power supply can continuously deliver to the components in the computer. It is a good idea to use a web calculator to calculate the optimal power output based on your chosen components.
Continuous operation thanks to redundancy
The core of the power supply consists of two separate power modules. If one fails, the second module immediately takes over the entire load without interrupting the power supply to the connected components. This architecture reduces the risk of server failure and supports the continuity of critical business processes. Furthermore, a faulty module can be replaced while the system is fully operational.
Efficiency and protection
The 80 PLUS Silver certification confirms energy efficiency, which reduces electricity consumption and waste heat production. A comprehensive set of protections protects the server from damage. The power supply integrates overvoltage, overcurrent, and thermal protection along with overload and short-circuit protection circuits. These mechanisms actively prevent hardware damage.
Advanced diagnostics and monitoring
The status of each module is indicated by coloured LEDs on the rear panel. In the event of a failure, an audible and visual alarm is activated, immediately informing the operator of the problem. Support for the I²C communication bus compatible with PMBus expands the possibilities for remote monitoring of voltage and current in real time. This gives administrators a detailed overview of the power supply status.
Designed for demanding deployments
The power supply's design ensures reliable operation in environments with operating temperatures up to 50°C. Its compact 1U format is suitable for standardised server cases. The cabling includes all the necessary connectors for the motherboard, processor, and add-on cards, including one 6+2-pin and one 6-pin PCIe connector for graphics accelerators.

80 Plus certification on the European market
The 80 Plus certification was created to objectively assess the efficiency of computer power supplies. This gives users a simple and clear comparison of individual models. On the European market (where 230V is used), there are six levels of 80 Plus certification with specified requirements for computer power supplies. Higher energy efficiency primarily means lower energy consumption.
