ANTEC CSK550 550W 80+ Bronze Non Modular ATX 2.0 Power Supply

The Antec CSK550 is a 550W non-modular ATX power supply from Antec's Cuprum Strike Bronze series, engineered to deliver stable, efficient power for mainstream desktop builds. Carrying the 80 Plus Bronze certification, the unit achieves up to 88% typical efficiency, which translates to less heat generated inside your chassis and lower energy drawn from the wall under real-world workloads. Cooling is handled by a 120 mm silent fan designed for quiet operation and extended service life — an important consideration in noise-sensitive home office or study environments. The fan draws heat away continuously without the noise associated with smaller, higher-RPM alternatives. Connectivity is generous for a non-modular unit at this wattage. The CSK550 ships with a 24-pin ATX motherboard connector, a single 8-pin (4+4) EPS 12V CPU connector, two 8-pin (6+2) PCIe connectors for discrete graphics cards, seven SATA power connectors for storage drives, two Molex connectors, and one FDD connector — providing ample headroom for mid-range builds with multiple storage devices. Protection is delivered through Antec's CircuitShield suite, covering over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), short-circuit protection (SCP), over-power protection (OPP), no-load operation protection (NLO), and over-temperature protection (OTP) — all seven safeguards working together to keep connected components safe from power anomalies. Active Power Factor Correction (Active PFC) ensures compatibility with a wide input voltage range of 100–240 VAC at 50–60 Hz, making the unit suitable for use across different regional power standards. The unit holds regulatory clearances including cTUVus, TUV, CB, RCM, CE, CCC, and FCC.
