SFX has been equipped with a P4 4pin power connector, 2 MOLEX connectors, 2 SATA connectors and a universal 24pin connector for motherboards. For a better cooling effect, it has an 80 mm silent fan with automatic speed control. The power supply is characterized by high efficiency above 70%. It was made of durable, galvanized steel.
The PFC filter and a number of protections (OVP, OCP, OPP, OTP, SCP, UVP) ensure stability of both the power supply itself and the powered components, protecting against damage, including motherboard and processor.
In the set with the power supply there is a power cable.
