Final Thoughts and Conclusions

As we expected, the EVGA 650W GQ power supply produced almost identical results to what we saw earlier this year when we reviewed the 750W GQ.  The smaller capacity 650W GQ version produced very good voltage regulation on all of the DC outputs along with good AC ripple and noise suppression. The power supply features a very good assortment of modular cables and delivers great efficiency, easily meeting the 80Plus Gold criteria. And just like we saw with the 750W version, the AC ripple values are a little higher than we might expect to see on some of EVGA’s premium PSUs but these are very reasonable numbers for a value oriented PSU and well below half of the ATX recommended guidelines.

All of the GQ power supplies incorporate EVGA’s ECO Intelligent Thermal Control System, which allows the power supply to operate in silent, fan-less mode at low to mid power levels. During our testing the 650W GQ was virtually silent up to mid-power range, even with the ECO fan-less mode turned off. The warranty period is five years for the new GQ series.  Once again, very good for a value minded power supply.

The MSRP for the EVGA 650W GQ power supply is $89.99 USD but you can find it online for $79.99 USD (, March 2016).
