Corsair RM850x 80 PLUS Gold, 850 Watts, Fully Modular ATX Power Supply Unit - Black

Product Information

A 135mm rifle bearing fan with a specially calculated fan curve ensures that fan noise is kept to a minimum, even at full load. CORSAIR RM Series Fully Modular Ultra-Low Noise Power Supplies with multiple EPS12V connectors deliver consistent 80 PLUS Gold efficient power to your PC and have all the connections needed to power today’s most demanding PC upgrades. Flat, sleeved black modular cables with clearly-marked connectors make installation fast and straightforward, with good-looking results.

The higher the efficiency levels the lower the thermal loads, so the cooling fan has less work to do and can rotate at lower speeds. The Corsair RM850x is the second-strongest member of the line, suitable for strong gaming systems since it can support all high-end AMD and Intel CPUs along with such power-hungry cards as the RTX 3080, RTX 3090, RX 6800 XT, and RX 6900 XT. It registers high performance in all areas: efficiency, load regulation, ripple suppression, transient response and, on top of that, it is dead silent as well. Five universal 8-pin connectors can be used with any 8-pin cable, satisfying all the power needs of modern motherboards and GPUs. The same care that goes into the design and testing of our renowned high-power enthusiast power supplies also goes into the TX-M Series semi-modular, because you need confidence and reliability regardless of your build budget.In the “SINGLE” position, the full output capability of the power supply’s +12V rail is available to any and all connectors, while in the “MULTIPLE” position, each individual connector has Over-Current Protection so no more than 40A of current can be delivered on any given cable.

With such great analogue platforms, someone could wonder why spend more on digital ones, where all major functions are controlled by micro-controllers instead of analogue ICs.

The minor rails are very strong with 150 W maximum combined power, and the 5VSB rail has the typical current output for a unit of this capacity.

The super-efficient operation of the TX Series semi-modular results in lower energy use and lower operating costs. When at low and medium loads, the fan stops spinning entirely until it's needed, resulting in virtually silent operation. For consistent, reliable power and superb electrical performance, each RMe Series power supply features a robust resonant LLC topology with DC-DC conversion and 105° rated industrial-grade capacitors. The Corsair Link cable has two headers that connect to the Corsair Link system sold separately; and it allows the PSU to connect with a USB header on the mainboard.

These durable and flexible cables come in triple-layer mesh paracord sleeving with included interlocking cable combs for an easy-to-install, professional looking build. Completely modular cables means you only connect the cables your system needs, and the wide range of included cables adds broad compatibility with modern graphics cards and motherboards.

Corsair decided to cooperate again with Seasonic and this is good news in our opinion, since this manufacturer has some great designs to show. CORSAIR provides a ten-year warranty on all RM Series power supplies; your guarantee of reliable operation that will last across several system builds. There are several actions that could trigger this block including submitting a certain word or phrase, a SQL command or malformed data.The cables are quite long but the distance between the peripheral connectors is small at only 100-110mm.

Complement your system's look with CORSAIR Premium Individually Sleeved Type 4 Gen 4 PSU Cables(sold separately), available in seven different colors and patterns. CORSAIR HX series power supplies give you extremely tight voltage regulation, quiet operation, Platinum-certified efficiency, and a fully modular cable set. This is excellent news because this bearing has the great endurance of double ball-bearings under high operating temperatures and the low noise output of a fluid dynamic bearing.
