Topside then, a 135mm thermally controlled fluid dynamic bearing fan spins up as needed, I think it is rated at 1800RPM. Even at decent load, you'll have a hard time hearing this PSU alright. It is very silent. Its dimensions are: 160mm x 86mm x 180mm. The unit weighs in at 1.93kg. The actual OEM of the RMx series we think might be Channel-Well Tech (CWT). CWT has been working with Corsair for a long time already and have proven themselves to be a very trust-worthy partner in terms of reliability and efficiency. Corsair is plugging this PSU with all Japanese 105°C capacitors for best reliability, and yeah well Corsair has increased its 7-year warranty towards 10 years now! 

  
When it comes to wiring we feel that there are enough connectors for this model, have a look at the supplied connectors, all with decent length by the way. The ATX motherboard connector is 60 CM, the Molex and SATA power cables 50 to 75 CM, the 8-pin CPU ATX power connector is at a great length of roughly 70 cm and the PCIe graphics connectors reach a lovely 75 cm as well. That is very nice.

The entire setup is modular, use the cables that you need and disregard the cables you don't need. It keeps the PC nice and tidy without an unneeded flurry-slash-spaghetti of redundant cables. All cables, including the 24-pin ATX cable, black sleeved type cables.
  

Above is a table showing the various cable configurations of the new Corsair RM850x. This model has plenty and lengthy cabling we feel.

When opened up we can now see that RMx (2018) units (550, 650, 750, and 850W) have moved to a wireless internal design, saving 20mm of space and bringing the size of the 750W and 850W units to a mere 160mm.
