Nexus is a long-established brand specializing in quiet PC components, mostly fans, power supplies, heatsinks and cases going back nearly a decade. Some Nexus products have long been used as reference quiet products at SPCR, the most notable being the Nexus 120mm "Real Silent Case Fan". Back in the day, some Nexus power supplies were also among the quietest available. In recent years, quiet power supplies became much more widely available as competition in this sector intensified, and the Nexus NX-8050 and 8060 were good and quiet, but no longer exceptional. The Value 430 put Nexus back on top as it turned out to be the quietest fan-cooled PSU ever reviewed.
The RX-8500 is a different animal altogether. It is the first Nexus PSU to enter the super high power realm; this 850W was joined recently by the RX-1K, a kilowatt model that appears to be part of the same series, with identical casing, fan and modular cables. With such high power ratings, there's no doubt that the target audience is the "serious" gamer (which always sounds like an oxymoron). Nexus claims that the RX-8500 is "the quietest 850 Watt model in the market." Such a claim is quite bold, because these days, there are many 850W power supplies that can be described as very quiet.
The biggest box of all Nexus PSUs.
It's quite well packed.
It's modular and comes with many output cables, but several thick cables are permanently attached.

80% efficiency; a minimum of 80%
efficiency guaranteed at all loads!

It's not 80 Plus certified, and 80% is no longer exceptional. 80 Plus Silver and Gold models offer up to 90% efficiency. |
|
Inaudible performance with Real Silent 13.5cm fan

Big fan usually means lower speed and noise... but we'll find out. |
Modular, sleeved cables.

Good |
Overvoltage and short-circuit protection
