Product information

Description

The Antec CSK650 650 W power supply unit delivers continuous power for desktop systems, featuring 650 W total output and a 20+4 pin ATX motherboard connector. Designed for broad compatibility, it accepts AC input from 100 to 240 V at 50/60 Hz and uses active PFC to improve voltage regulation and efficiency. The unit is 80 PLUS Bronze certified with up to 88% efficiency, and it incorporates a 120 mm silent fan for active cooling. The chassis is finished in black and the PSU is supplied with cables of varying lengths for motherboard and SATA connections, enabling straightforward installation in most mid-tower and full-tower cases.

Advantages

The CSK650 combines 80 PLUS Bronze efficiency with a quiet 120 mm cooling fan to produce a stable and energy-conscious power source for everyday and performance-oriented PC builds. CircuitShield protection features provide multiple industrial-grade safeguards for voltage and current anomalies, while active PFC contributes to smoother operation and lower heat generation. The unit’s compact weight and standard connectors make it compatible with a wide range of systems and simplify installation and cable routing.

Suitable for

  • Home and office desktop PCs requiring up to 650 W continuous power
  • Gaming and multimedia systems with single-GPU configurations
  • System upgrades where 20+4 pin ATX compatibility is required
  • Builds that prioritise a balance between efficiency and cost

Key specifications

  • Total power output: 650 W
  • Efficiency: up to 88% (80 PLUS Bronze)
  • Motherboard connector: 20+4 pin ATX
  • Input voltage range: 100–240 V AC
  • Input frequency: 50/60 Hz
  • Cooling: 120 mm silent fan
  • Protection suite: industrial-grade over/under voltage and short-circuit protections (CircuitShield)
  • Colour: Black
  • Weight: 1.95 kg

How to use

Install the PSU into a compatible PC case following the case manufacturer’s mounting instructions and standard safety precautions: switch off and unplug the system before beginning, position the unit so the fan intake has adequate airflow, and secure it with the supplied screws. Connect the 20+4 pin ATX cable to the motherboard, then attach SATA and peripheral cables to storage drives and accessories as needed. Verify all connectors are fully seated before powering on. Ensure the input voltage selector (if present) matches local mains voltage or use the auto-sensing feature where applicable.

Usage recommendations

For reliable operation, maintain sufficient case airflow and avoid operating the PSU near heat sources. Use the CSK650 within its rated power envelope and allow occasional brief load increases but avoid continuous overload. Regularly inspect cables and connections for wear, and consult Antec support for warranty-covered repairs or replacements under the 3-year warranty.
