Overview
The Antec Atom V450 V2 is a 450W non-modular ATX power supply designed to deliver reliable, stable power to budget and mid-range desktop builds. Part of Antec's Atom Series, this V2 revision brings improved thermal management and Antec's CircuitShield industrial-grade protection suite, making it a dependable choice for everyday computing and entry-level gaming rigs. At the heart of the Atom V450 V2 is a 120mm silent fan governed by Antec's Thermal Manager, an advanced fan control system that modulates fan speed based on real-time heat load. This helps keep acoustics low during light workloads while ramping up airflow only when needed, striking a balance between cooling performance and noise levels. CircuitShield protection covers four key safeguards: Over Voltage Protection (OVP) guards sensitive components against voltage spikes, Over Current Protection (OCP) prevents excessive current draw, Short Circuit Protection (SCP) instantly cuts power in a fault condition, and No Load Operation (NLO) ensures stable behaviour even without a connected load. Together, these protections help shield your CPU, GPU, and storage devices from common power anomalies. The unit complies with the Intel ATX12V Version 2.31 standard, ensuring broad compatibility with modern motherboards. Its fixed cable harness provides all the connectors a typical build requires without requiring cable management add-ons. Verified Specifications: - Model: ATOM V450 V2 - Max.
