The EVGA 850 G7 is one of the best 850W units the market today. The Corsair RM850x (2021) is close in performance and has an advantage in noise output, while the 850 G6 loses notably in performance but achieves a significant win in noise output. The performance FSP delivered out of such a compact platform is impressive. We can't stop thinking, though, about the improvement in noise output with a larger PCB and cooling fan. Downsizing high-capacity PSUs at that degree comes at a cost, of increased noise output, under harsh conditions.
Besides the tiny footprint, the top performance, the fully modular cable design and the high build quality, EVGA threw in LED load indicators on one of the PSU's sides. Someone can argue that it would be better if an external PCB hosted these LED indicators, which the user could install on top of their desk to be easily accessible. This sounds good, but it would also likely increase the cost. We also noticed is that FSP used two different bulk caps in this unit, with the second provided by a less known manufacturer. We would like to see both caps have the same quality.
The EVGA 850 G7 brings up memories of the legendary G2 units, which were among the best PSUs that EVGA ever offered. We are eager to see the upgraded G7 versions featuring the new 12+4 pin PCIe connectors and ATX 3.0 support.
