A Detailed Look
The EVGA SuperNOVA G2 power supply enclosures are painted with a flat black hammertone finish and measure 180mm (7.1”) long. The back panel includes an On-Off switch, AC receptacle and a small 2-position switch labeled “ECO OFF/ON”.
The SuperNOVA G2 power supplies incorporate EVGA’s ECO Intelligent Thermal Control System for fan speed control. This allows the end user to select silent, fan-less operation for low to mid power applications.

With the ECO Thermal Control System turned ON, the power supply cooling fan does not start spinning until the internal component temperatures reach a pre-programmed setting. The fan then operates at low (750 rpm) or high speed (1500 rpm) based on load and temperature (see graph above).
Both power supplies use a 140mm, seven blade fan on the bottom for cooling. The dual ball bearing Globe Fan (RL4Z B1402512HH) is rated for 0.50A at 12 VDC and is controlled by the ECO Thermal Control System.
The front panel incorporates twelve modular cable connectors, all nicely labeled.
The SuperNOVA G2 power supplies come with a good assortment of all modular cables and connectors. All of the cables are sleeved. As we mentioned previously, the cable sets for the 750 G2 and 850 G2 are very similar, except the 750 G2 gives you four 6+2 pin PCI-E connectors, while the 850 G2 provides four 6+2 pin and two 6-pin PCI-E connectors.
