1600W Fully Modular ATX Power Supply

The EVGA SuperNOVA 1600 G2 delivers 1600W of continuous power for high-end desktop systems. It uses a single +12V rail rated at 133.3A to support multi-GPU configurations and heavy overclocking. 80 PLUS GOLD certification confirms up to 90% efficiency at typical loads. The unit accepts 115-240V input at 50/60Hz for worldwide compatibility.

Fully Modular Cable Installation

A fully modular design lets you connect only the cables your build requires, reducing internal clutter and improving airflow. The package includes nine 8-pin (6+2) PCIe connectors, five 6-pin PCIe connectors and sixteen SATA power connectors for extensive drive support. Japanese Nippon Chemi-Con solid-state capacitors are used throughout for long-term reliability. A 140mm double ball bearing fan provides cooling across the 220mm chassis length.

Sustained Load Behaviour

LLC resonant circuit topology combined with full DC-to-DC conversion maintains stable voltage regulation during extended high-wattage operation. Over-voltage and overload protection circuits safeguard components if draw exceeds safe limits. The single-rail architecture distributes the full 1600W capacity without per-rail balancing constraints. Efficiency remains high across a broad load range, limiting waste heat during prolonged compute or rendering sessions.
