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.

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.

Really nice PSU, as always, from EVGA. Are the LEDs on when the PSU is connected with power, but the system is power down? Those LEDs will be really helpful when trying to connect a power cable but the room lighting doesn't help.

PS. I am reading that some EVGA FTW like going SuperNOVA because of bad PWM cooling.

Here's some thermal pads suckaz, fix it yourself, signed EVGA! The FTW line of GPUs should be calld the WTF line. I'd RMA that crap right back to EVGA, let them fix it!

If the user has to apply the pads does it void the warranty?

Based on an email that a Greek forum member got from EVGA as a reply, they do NOT acknowledge a problem, they insist that the cards DO NOT need those pads. They just give those pads as a free service to their customers. Funny right? Cards don't need pads, but take them and use them.

No, unfortunately the LEDs only come On when the PSU turns on.

Pity. It would have been a useful feature, rarely necessary, but useful.

You said :
• (1) 20+4 pin ATX
• (1) 8-pin EPS/ATX12V
• (4) 6-pin PCI-E
• (2) SATA
• (2) Molex

At second page there was 2x 8-pin EPS, which one is correct?

The full specs are given on page two, which list two 8-pin (4+4) ATX/EPS connectors - this is correct.

The table you quoted is a list of the connectors I used for testing (however, it should have shown two 8-pin EPS being used instead of one - fixed). Sorry for the confusion.

gold should be made a defualt standard for power supply units, and should be starting at 60$ to save the world energy/environmental crisis

that would put a lot of people out of a job fixing PC's for a living. LOL
