A Detailed Look
The EVGA Supernova 750W G2L power supply enclosure is painted with a matte black hammertone finish and measure 165mm (6.5”) long. The back panel includes an AC receptacle, main power On-Off switch, LED lights On-Off switch and an ECO Thermal Control fan mode switch (On enables fan-less operation).
The 750 G2L power supply incorporates EVGA’s ECO Thermal Control System for fan speed control. This allows the end user to select silent, fan-less operation for low to mid power applications if desired.
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 starts out at low speed and gradually ramps up based on load and temperature (see graph above).
The power supply uses a 135mm, seven blade fan on the bottom for cooling. The Globe Fan (RL4ZB1352512HH) is rated for 0.45A at 12 VDC and is controlled by the ECO Thermal Control System. It features ball bearings for extra-long life and quiet operation.
The front panel on the 750W GQ incorporates eleven modular cable connectors that incorporate white LED lights. This gives a cool lighting affect for cases with a side window.
All of the modular cables are sleeved with a black nylon mesh covering.
Under the Hood
Here are a few pictures showing the layout and components inside the EVGA Supernova 750W G2L power supply. Just like the original G2 series, the G2L Series is based on Superflower’s Leadex platform.
The new G2L series features a modern LLC resonant circuit design with DC-to-DC converters for increased efficiency. The layout of components is clean while the soldering appears to be very good. All of the capacitors used inside the G2L PSU are high-quality Japanese made (primarily Nippon Chemi-con) electrolytic and solid polymer caps. The 750W GQ uses a single primary capacitor rated for 680uF, 400V and 105°C.
