ANTEC ATOM V550 550W V2 Non Modular ATX 2.0 Power Supply

The Antec Atom V550 V2 is a 550W non-modular ATX power supply designed for mainstream desktop PC builds that demand reliable power delivery without unnecessary complexity. Built to comply with the Intel ATX12V 2.31 standard, this unit slots cleanly into standard ATX mid-tower and full-tower cases, making it a straightforward choice for everyday productivity machines, entry-level gaming rigs, and home office systems. Cooling is handled by a 120mm silent fan paired with Antec's Thermal Manager — an active fan-control system that adjusts fan speed based on internal temperature, keeping noise levels low during light workloads and ramping up only when thermal conditions require it. The result is a quieter computing environment under typical use. Protecting your components is Antec's CircuitShield technology, which bundles four hardware-level safeguards: Over Voltage Protection (OVP), Over Current Protection (OCP), Short Circuit Protection (SCP), and No-Load Operation (NLO) protection. These circuits monitor rail voltages and current continuously, cutting power to downstream components if unsafe conditions are detected. The fixed cable harness provides a generous connector set suited to mid-range builds. Two 8-pin (6+2) PCIe connectors support a single mid-range discrete GPU, while five SATA connectors accommodate storage arrays and optical drives. A single 8(4+4)-pin EPS 12V connector serves the CPU, and two Molex plus one FDD connector round out legacy peripheral support.
