ANTEC EarthWatts 750G 750W Pro 80 + Gold Semi Modular ATX 2.0 Power Supply

The Antec EarthWatts EA750G Pro is a 750W semi-modular ATX power supply built around an 80 Plus Gold certification, which means it operates at up to 92% typical efficiency across a wide load range. That higher efficiency translates directly into lower energy consumption and reduced heat output inside your chassis — a meaningful advantage for any mid-to-high-end gaming or workstation build. At the heart of its design is Antec’s PhaseWave topology: a server-class full-bridge LLC circuit combined with synchronous rectification and a DC-to-DC conversion stage. This approach keeps output voltages stable under shifting loads, particularly on the 12V rail, which carries approximately 99% of the unit’s capacity to optimally feed modern CPUs and discrete GPUs. Four PCI-E connectors are provided, supporting multi-GPU configurations where needed. The semi-modular cabling design keeps essential ATX and EPS leads permanently attached while allowing peripheral cables to be connected only as required. This simplifies installation, improves internal airflow, and reduces cable clutter without sacrificing flexibility. Cooling is handled by a 120mm fan governed by Antec’s Thermal Manager, which adjusts fan speed based on load and temperature. The result is near-silent operation during light and medium loads. Japanese heavy-duty capacitors reinforce DC stability over the unit’s full rated lifespan. CircuitShield industrial-grade protection is integrated throughout, including Over Current Protection (OCP) and a full suite of additional safeguards that help prevent damage to connected components during fault conditions. The power supply is ATX12V 2.4 compliant and holds ErP Lot 6: 2013 compliance for standby energy efficiency.
