ANTEC Atom G650 80 + Gold Fully Modular ATX 2.0 Power Supply

The ANTEC Atom G650 is a 650W fully modular ATX 2.0 power supply unit carrying the 80 PLUS Gold efficiency certification. This rating means the unit delivers high efficiency across a range of load conditions, helping to reduce wasted energy and lower electricity consumption compared to lower-rated alternatives. Full modularity means every cable — including ATX main, CPU, and peripheral connectors — is detachable. You connect only the cables your build actually needs, reducing clutter inside the chassis, improving airflow, and making cable management substantially easier during assembly or upgrades. Cooling is handled by a 135mm silent fan paired with ANTEC’s Thermal Manager, an intelligent fan-speed control system that modulates fan RPM based on internal temperatures. The result is quieter operation during light loads and adequate airflow under heavier demand. ANTEC’s CircuitShield protection suite provides industrial-grade safeguards covering Over Current Protection (OCP), Under Voltage Protection (UVP), Over Voltage Protection (OVP), Over Power Protection (OPP), Short Circuit Protection (SCP), Over Temperature Protection (OTP), and No-Load Operation (NLO) protection. This multi-layer design helps shield connected components from potentially damaging electrical events. The unit uses Active Power Factor Correction (APFC) and a DC-to-DC conversion topology, which contributes to stable voltage regulation across the +12V, +5V, and +3.3V rails. Flat ribbon cables are included to assist with routing in tighter spaces.
