Final Thoughts and Conclusions
Overall the new EVGA SuperNOVA NEX750G Gold power supply proved to be a bit of a disappointment. Since it bears the SuperNOVA name and is advertised as being a premium, enthusiast grade power supply we hoped it would have similar features to the flagship NEX1500 but in fact the NEX750G is built on an entirely different platform and does not support EVGA's SuperNOVA monitoring software. The NEX750G appears to be aimed at more mainstream, cost-conscious consumers. However performance and pricing are very competitive at this power point, which puts a lot of pressure on the NEX750G to excel.
The EVGA SuperNOVA NEX750G Gold power supply operates very efficiently and easily meets the 80 Plus Gold criteria for efficiency. It comes with a good assortment of all modular cables that include two pairs of 4+4 pin ATX/EPS 12V connectors and eight PCI-E connectors. Voltage regulation and AC ripple suppression were within specification and acceptable, but not as good as we would expect from a premium brand, enthusiast power supply. And while the cooling fan is advertised as being "quiet… for near-silent operation" it proved to be far from it.
The EVGA SuperNOVA NEX750G Gold power supply is currently available and selling for $139.99 USD ($129.99 after MIR, newegg.com January 2013), which makes it a little on the expensive side given the stiff competition in this power range.
