ANTEC Atom B650 650W 80+ Bronze Non Modular ATX Power Supply

The ANTEC Atom B650 is a 650-watt non-modular ATX power supply carrying the 80 PLUS Bronze certification, meaning it meets independently verified efficiency thresholds at varying load levels. Active Power Factor Correction (Active PFC) is built in, helping to stabilise the power drawn from your wall outlet and reduce reactive losses under both high and low workloads. Cooling is handled by a 120 mm silent fan designed for low-noise operation across the unit’s rated operating temperature range of 0–40 °C. The fan’s larger diameter allows it to move sufficient airflow at lower RPM compared to smaller fans, keeping acoustic output down during everyday computing tasks. Protection circuitry carries ANTEC’s CircuitShield branding and covers over-power protection (OPP), over-voltage protection (OVP), under-voltage protection (UVP), and short-circuit protection (SCP). These mechanisms are intended to safeguard connected components should an unexpected electrical event occur. The fixed, non-modular cable configuration keeps costs down and ensures a secure connection, though unused cables will need to be managed inside the chassis. The connector set supports a broad range of mainstream ATX builds including systems with a single mid-range discrete GPU. The unit is backed by a 3-year manufacturer warranty as listed in the product specification sheet.
