Product is made of high quality components. The power supply has a 3x SATA connectors, 2x MOLEX connectors, P4 4-pin connector and a universal 20+4-pin motherboard connector. Supports ATX 12V 2.0 specifications, so it can be used with current and next generation of platforms with multi-core processors. Efficient, quiet fan with automatic speed control and a diameter of 120 mm ensures effective cooling. The power supply has a manual switch that allows the user to safely cut off power without having to disconnect the cord from the network. High efficiency above 70% allows effective supplying and so the stable operation of the power supply affects the reliability of all components of the computer.
An important aspect is the presence of several important protectors (OVP, OCP, OPP, OTP, SCP) and PFC filter that protects and prevents motherboard, processor and other parts from damage and stabilize the operation of the power supply so that it works without any unwanted interference.
