Adata does a strong come back in the PSU market, through its XPG sub-brand. The Core Reactor units offer high performance and increased reliability, thanks to the modern platform from Channel Well Technology, which uses good parts. In the output noise area, there is room for improvement, though, given that the Corsair RMx line has set the bar pretty high in this section. Even the noise that the PSU makes can be a problem for sensitive users.
If you don't want to spend so much money and practically don't care about the alternative sleep more support and the high efficiency under light loads, you could take a look at the RM850x (or the RM850) and the more expensive EVGA 850 G3, which is among the best PSUs in this category.
