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

Product Information

I should also point out that I haven’t used the new scoring algorithm for the above graphs because I don’t have data for all PSUs, especially some older ones. CORSAIR offers a ten-year warranty on all RMx series power supplies, your guarantee of reliable operation that will last across several system builds. To check the functionality of the power supply, you can perform a simple test by shorting the green wire (PS_ON) with any black wire (COM) in the 24-pin ATX power connector. 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.

If you plan to overclock a system with similar specifications considerably, you are better off with the RM1000x. At low and medium loads the cooling fan switches off entirely for near-silent operation, but once the action picks up, the fan activates, ensuring critical component temps stay in check. GPUs that require 3 cables are fine running on two pigtail cables, connected to the 3 PCIE connexions. Overall, the Corsair RM850x appears to be a capable and efficient computer adapter with a high total power output and well-distributed power outputs for different components.

I prefer the ML fan over the FDB one since it is more reliable, especially at high operating temperatures. The RM850x is my current (primary-PC) PSU ,for about 2 years now and i’m extremely satisfied by its performance. With precise timings, RMx supports Microsoft Modern Standby, ensuring extremely fast wake-from-sleep times and better low-load efficiency. Since this is an older unit, don’t expect to find 12VHPWR connectors, but I am sure Corsair will soon update its RMx line offering the new PCIe connectors. From individually sleeved cables in a variety of color combinations to 12-pin micro-fit GPU cables and 12VO motherboard cables, complete your build your way.

Corsair continues with a single 12V rail and enables the entire capacity to be meted out at an ambient 50°C. As before, five sensible capacities ply the range - 550W, 650W, 750W, 850W, 1,000W - and certification stays at 80 PLUS Gold. For consistent, reliable power and superb electrical performance, each RMx Series power supply features a robust resonant LLC topology with DC-DC conversion, and 105°C rated 100% Japanese electrolytic capacitors. The better your problem and question is described, the easier it is for other Corsair owners to provide you with a good answer.The ML bearing fan greatly enhances the PSU’s reliability since magnetic bearings don’t have a problem operating under harsh conditions for prolonged periods. CORSAIR RM850x Series fully modular power supplies with EPS12V connectors are built with the highest quality components to deliver 80 PLUS Gold efficient power to your PC,with virtually silent operation. Magnetic Levitation Fan: Utilizes a magnetic levitation bearing and custom engineered rotors for high performance, low noise, and superior reliability. Supports Modern Standby sleep mode for extremely fast wake-from-sleep times and better low-load efficiency. I haven't got the PSU yet but have seen that this is the case in a couple of reviews and on looking at the product page as well.
