About this deal

i7 8086K, AORUS Z370 Gaming 5, 16GB GSKILL RJV DDR4 3200, EVGA 2080TI FTW3 Ultra, Samsung 970 EVO 250GB, (2)SAMSUNG 860 EVO 500 GB, Acer Predator XB1 XB271HU, Corsair HXI 850W. I always like to see a mixture of straight and 90 degree angled SATA connectors, as it can help the build phase in some chassis. Zero RPM Fan Mode: Since the fan doesn’t turn on until it’s needed, you’ll enjoy virtually silent operation at low and medium loads. Well this means we can eliminate secondary noise pollution in the test room and concentrate on components we are testing.

It's powerful enough to accommodate a high-end PC with more than two graphics cards and a potent CPU. Inside the box, alongside the power supply is a user manual, regional specific power plug, warranty guide, and a soft bag of modular cables. I would imagine they are using another NR135P fan, but will get a better look when we open the unit shortly. The 8 pin cables for EPS 12V, ATX12V and PCIe have added capacitors to help reduce ripple noise via the cables.And with the proliferation of new high end boards expecting 8+4 or 8+8 CPU power connections only 1 would be a poor fit for the enthusiast market. There’s no more unwieldy mythical tentacled monstrosity of unused cables to clutter up the inside of your case. The original HX520W and the HX620W are now but a distant memory, yet the HX series is still targeted towards demanding PC enthusiasts, consisting of eight high output (750-1200 Watt) units with very impressive specifications. Yeah, that design is not really suitable for modern systems, I'm still running them (even got a first-gen S12 in service), but they're on older PCs that aren't worth much. Add in the seven year warranty and for many it was a no-brainer that this was the power supply to have for mid-range systems.

We already reviewed the HX1200 and HX1000, so we have a pretty good idea how the HX family performs. The RMx series for instance is a 80 Plus Gold certified, fully modular range incorporating a 135mm rifle bearing fan inside. Our results highlight that load regulation is very good, and the HX850 Platinum also passed the cross load test without a hitch. Unfortunately, we cannot identify the OEM of the fan but we can tell that it is a quality model with a fluid dynamic bearing engine for longevity. The 135 mm fan responsible for the cooling needs of the HX850 is the Corsair NR135P, a fan we frequently see in the company’s high-performance PSUs.Ryzen 7 3700x | Asus B450-F Strix | 16gb Gskill Flare X 3200mhz | Corsair RM550x PSU | Asus Strix GTX1070 | 250gb 860 Evo m. Built with all Japanese 105°C capacitors, they’re a great choice for high performance PCs where reliability is essential.
