You cannot call bad, or even mediocre, the EVGA SuperNOVA 850 P6, but it is a massive letdown that not only does it score lower than the 850 G6, but it is also noisier, too! Given the higher efficiency, we expected better performance and lower noise output. Seasonic has to tune this platform more to show its full potential and become more competitive. Till this happens, we cannot recommend it since at the same price, you can get the Thermaltake Toughpower PF1 850, which offers almost 4% higher overall performance.
The build quality of the 850 P6 is high and the extra-long warranty is a huge asset, but these two features are also present in the less expensive 850 G6 model, and at the time of the review the price difference between these products was 50 dollars.
This makes the 850 G6 a better choice. EVGA should rethink its pricing schemes for the G6 and P6 lines and push Seasonic to make some changes in the latter line, to improve performance. It is high time for new platforms, which will also be compatible with the upcoming ATX 3.0 spec and the new GPUs.
