The ANTEC CSK550DC EC is a power supply unit that provides a total continuous output of 550 watts. It is engineered to deliver a consistent and stable current to all system components, a critical factor for maintaining performance during varied computational workloads. This unit is primarily intended for mid-range computer builds where dependable power is required without the need for higher wattage capacities. The design focuses on functional, steady power delivery suitable for a range of standard desktop configurations.
This power supply incorporates a comprehensive suite of industrial-grade safety protections to safeguard connected hardware from electrical irregularities. These circuits include over-voltage (OVP), over-current (OCP), over-power (OPP), and short-circuit (SCP) protection, among others. Compatibility with a wide array of motherboards is facilitated by the standard 20+4 pin main power connector. The unit is housed in a black enclosure, allowing it to integrate visually into the majority of system builds.
Key Features:- Provides a total power output of 550W
- Equipped with a 20+4 pin main power connector
- Features OVP, OCP, OPP, SCP, OTP, and UVP safety protections
