Summary: The RX-6300 represents the first time we have reviewed a power supply from Nexus and one of the few times we have seen an ATNG based unit. In the past, ATNG units have been very much mediocre in our testing but hardly what we would call bad units. Nexus on the other hand has a history of producing a range of high quality quiet cooling products.
Summary: Nexus RX-6300 was a really nice surprise, with efficiency between 83.2% and 86.6% in our tests. Although it is not 80 Plus certified, it achieved a performance that would easily get an 80 Plus Bronze certification, if the manufacturer wanted to.
We could easily deliver its labeled power at 50° C and we could overload this baby up to 840 W without burning it.
Summary: Nexus has a sleek, solid, silent PSU in the RX-6300. While the short EPS12V cable will certainly be a concern to some, every other aspect of performance is stellar. If you’re looking to build a silent PC for a home theater, a file server, or any other situation where noise is a no-no, this power supply will not disappoint.
Summary: The Nexus RX line of power supplies are currently available in wattages ranging from 530 to 1000. So you are bound to find a PSU to fit your power needs and budget. The 630W model performs really well, even with an HD 5870 Video Card installed. It also come with an ultra quiet 135mm fan, modular design and is efficient.
