The overall performance is similar to the Seasonic Focus Plus Gold 750, which uses the same platform. The RM750 earns top place in the performance charts, while the RM750x scores lower because we made some changes in our overall performance algorithm, taking into account more factors. On top of that, we measured a new RM750x, which didn't perform as well as the previous one.
The graph below depicts the cooling fan's average noise over the PSU's operating range, with an ambient temperature between 30 to 32 degrees Celsius (86 to 89.6 degrees Fahrenheit).
The fan speed profile could be more relaxed.
The following graph shows the PSU's average efficiency throughout its operating range with an ambient temperature close to 30 degrees Celsius.
The overall efficiency is inline with the competition's offerings.

Nice-looking PSU. The only problem is that these days, people don't know which way to turn with all of these re-branded PSUs. As you stated, this is the same as the SeaSonic, which makes it good, but there are so many good PSUs that the market is just saturated. Names like EVGA, Antec, Corsair, and Be Quiet! are all top-tier and well-respected names.Reply
Then in the second tier you get names like Cooler Master, Thermaltake, Gigabyte and ASUS. This NZXT could easily get lost in the mix.
a bit late but a question about the noise level, it says 33 decibels average across usage, but if im only using say 550W max load is it ever going to hit that 33 decibels? its the only thing stopping me from picking one up at the momentReply
