ANTEC Atom B650 V2 650W 80+ Bronze Non Modular ATX Power Supply

The ANTEC Atom B650 V2 is a 650-watt ATX power supply designed to deliver stable, efficient power to mainstream desktop builds. Carrying the 80 PLUS Bronze certification, it meets a defined efficiency standard at multiple load levels, helping to reduce wasted energy during everyday use compared to uncertified units. Active Power Factor Correction (APFC) is built in, which improves the quality of power drawn from the mains and helps the unit work more efficiently across a range of input conditions. The unit ships with a flat cable harness, keeping cable routing tidier inside a mid-tower or micro-ATX chassis without the need for cable combs or ties. Thermal management is handled by a 120 mm fan paired with ANTEC’s Thermal Manager system, an automatic fan speed controller that adjusts airflow in response to internal temperature and load. The result is quieter operation during light workloads while maintaining adequate cooling under sustained load. ANTEC’s CircuitShield protection suite provides industrial-grade safeguards: Over Power Protection (OPP), Over Voltage Protection (OVP), Under Voltage Protection (UVP), and Short Circuit Protection (SCP). These protections help safeguard connected components against common power-delivery faults. This is a non-modular unit, meaning all cables are permanently attached. While this limits flexibility in cable management compared to semi- or fully-modular designs, it eliminates the risk of loose connector seating and is a common choice for budget-conscious builds. The Atom B650 V2 is backed by a 3-year parts and labour warranty from ANTEC.
