Product information

Description

The Antec Cuprum Strike CSK550 550 W is a mid-range internal power supply unit designed for desktop PCs. It provides continuous 550 W output with up to 88% efficiency and 80 PLUS Bronze certification. The unit includes a 20+4 pin ATX motherboard connector, active PFC, and a 120 mm cooling fan. SATA power cable lengths vary (500, 650, 800 mm) to accommodate different drive layouts, and the supply is finished in black with a compact footprint and a weight of approximately 1.53 kg.

Advantages

The CSK550 combines energy efficiency and built-in protective features to deliver stable power while minimizing heat and noise. Its 80 PLUS Bronze rating and up to 88% efficiency reduce wasted energy. A 120 mm silent fan provides active cooling with lower acoustic output, and the CircuitShield protection suite safeguards the system against common electrical faults. The mix of cable lengths for SATA connections improves cable routing flexibility inside diverse PC cases.

Suitable for

  • Home and office desktop PCs with moderate power demands
  • Workstations with multiple storage drives requiring flexible cable routing
  • System builds where quiet operation and energy efficiency are desired

Key specifications

  • Total power: 550 W continuous output
  • Efficiency: up to 88% (80 PLUS Bronze)
  • Motherboard connector: 20+4 pin ATX
  • Cooling: 120 mm silent fan
  • Input voltage range: 100–240 V AC
  • Cable lengths for SATA connectors: 500 mm, 650 mm, 800 mm
  • Active PFC and CircuitShield protection suite
  • Colour: Black; Weight: approximately 1.53 kg

How to use

Install the power supply into a compatible ATX case following standard safety precautions: disconnect mains power, ground yourself to avoid static discharge, and secure the unit with the provided mounting screws. Connect the 20+4 pin ATX connector to the motherboard and attach SATA power cables to drives as required, choosing appropriate cable lengths to minimize clutter. Ensure the AC input is within the 100–240 V range and that the case airflow is not obstructed to allow the 120 mm fan to provide adequate cooling.

Usage recommendations

For reliable operation, pair the CSK550 with systems whose total continuous power draw does not exceed the unit’s 550 W rating. Maintain good case airflow to optimize fan performance and keep operating temperatures low. Periodically check cable connections and dust buildup around the fan to sustain efficiency and quiet operation.
