Get the most reliability and greatest performance with the use of the highest possible quality Japanese capacitors.
A high-quality fluid dynamic bearing fan gives the GM Series excellent reliability and thermal performance. EVGA Auto ECO mode ensures the power supply stays completely silent during low to medium loads. The fan does not spin until necessary, allowing for completely silent operation!

Tight Voltage Regulation (<2%)
A single +12V rail offers the best power output, rail stability and compatibility with the latest hardware. EVGA SuperNova GM power supplies provide up to 70.8A on a single rail!
