Antec CSK550 80 Plus Bronze SMPS

The Antec CSK550 is part of Antec's Cuprum Strike Bronze series — a line of power supplies engineered to deliver stable, continuous power for mainstream desktop builds. With an 80 PLUS Bronze certification, the unit operates at up to 88% typical efficiency, reducing heat output and lowering energy waste compared to uncertified alternatives. Active Power Factor Correction (Active PFC) further improves energy draw quality from the wall, helping components receive cleaner, more consistent power across varying load conditions. Cooling is handled by a 120mm silent fan designed to keep acoustic levels low during everyday operation. The fan's longer-lifetime design suits always-on workstations and gaming rigs alike. Internally, the CSK550 features Antec's CircuitShield suite of industrial-grade protections covering Over Current Protection (OCP), Over Voltage Protection (OVP), Under Voltage Protection (UVP), Short Circuit Protection (SCP), Over Power Protection (OPP), No Load Operation (NLO), and Over Temperature Protection (OTP) — meaning the unit will shut itself down before damage can reach your motherboard, GPU, or storage drives. The connector layout covers a wide range of modern ATX builds: a 24(20+4)-pin motherboard connector, one 8(4+4)-pin EPS 12V for the CPU, two 8(6+2)-pin PCIe connectors for discrete graphics cards, seven SATA power leads, two 4-pin Molex peripherals, and one FDD connector.
