Antec Atom V550 550W Power Supply

Dependable Electrical Foundation Built to Intel Standards

Equip your everyday desktop rig with a consistent and stable source of power. The Antec Atom V550 is precisely engineered to align with established Intel ATX 12V configuration standards, making it an excellent match for multi-core processors and basic graphics setups. Whether you are assembling a brand-new home office workstation or repairing an existing system used for web browsing, data management, or digital learning, this power supply provides the operational stability required to keep your systems running smoothly.

140mm Compact Physical Footprint for Easy Building

Streamline your internal system assembly and reduce structural clutter. Designed with a highly optimized, compact 140mm depth profile, this ATX power unit slips effortlessly into standard mid-tower enclosures as well as tighter, space-restricted budget cases. The shortened chassis footprint provides additional clearing space inside your power supply shroud, leaving plenty of room to route cables cleanly, store excess wiring slack, and maintain unrestricted airflow pathways across your other primary hardware components.

Silent Fan Thermal Engineering and Smart Cooling

Maintain a quiet, distraction-free work or study zone. The internal cooling layout features a specialized 120mm silent fan managed by an integrated thermal sensor. This smart manager automatically monitors internal heat loads, spinning the fan at lower, whisper-quiet speeds during routine desktop tasks and scaling up cooling output only when your system tackles more demanding rendering workflows. This keeps acoustics low while ensuring vital electrical circuits stay well within safe thermal thresholds.

Industrial-Grade Circuit Shield System Protection

Safeguard your delicate internal processing components from unexpected electrical threats. The Atom V550 comes fortified with Antec’s signature Circuit Shield, an industrial-grade suite of built-in hardware defenses. This comprehensive protective barrier includes Over Voltage Protection (OVP), Over Power Protection (OPP), Short Circuit Protection (SCP), and Under Voltage Protection (UVP), acting as an active line of defense to safely shut down your system before power irregularities can cause component wear or data corruption.
