The Fractal Design Newton R3 comes with a cable for just about everything you'd want and need. The only thing that I'm not much of a fan of is that two of the PCI-E cables are natively wired and I would like to see that only one of them be this way. It is my experience that most users of 700W-800W power supplies only have a single GPU in their system, so that leaves an unnecessary cable just hanging inside the PC. Other than that, there isn't anything to complain about.
Rail distribution is as simple as it gets with a single 12V rail. There is no need to worry about load balancing here.
A Look Inside
Plenty of passive cooling is present with a layout that isn't overly crowded. There are also some green and gold capacitors in the top left which doesn't look good for that claim of 100% Japanese capacitors on the back of the back of the box.
A pair of Nippon Chemi-Con bulk capacitors sit on the primary side of the power supply.
The secondary side is littered with a bunch of Teapo caps. This is the first time that we've caught someone stating that their units featured 100% Japanese capacitors and it didn't, so we certainly aren't happy about this at all.
Fractal Design uses their own 140mm fan to provide the active cooling for the Newton R3 800W power supply and it is rubber mounted to help reduce noise from vibrations.
