Final Thoughts and Conclusions

During previous reviews of both the original EVGA G2 and G2L power supplies we found they delivered excellent performance with minimal noise. Now EVGA has raised the bar even higher with the introduction of the new G3 Series. Voltage regulation and AC ripple suppression are outstanding and as good as or better than before.

The EVGA 550W Supernova G3 power supply exhibited outstanding voltage regulation on all of the DC outputs along with excellent AC ripple and noise suppression. The power supply features a good assortment of modular cables and delivers great efficiency, easily meeting the 80Plus Gold criteria.

The 550W G3 PSU incorporates EVGA’s ECO Thermal Control System, which allows the power supply to operate in silent, fan-less mode at low to mid power levels. The warranty period is 7 years for the 550W and 650W model and 10-years for the 750W, 850W and 1000W units.  Overall, an outstanding new power supply from EVGA.

As you might expect, introductory pricing is still a little on the high side compared to other 80 Plus Gold PSUs in the same power range. However, prices may fall as these new units become more widely available.

•    EVGA SuperNOVA 550W G3 ($89.99 USD)
