Customers frequently mention the RMx Series RM850x's excellent performance and quiet operation as major strengths. Its fully modular design and ease of installation are also frequently praised, simplifying cable management and the overall building process. While some users noted its larger size, the positive feedback overwhelmingly focuses on its reliability and value. The power supply is considered a great option for its price point.

    Not enough PCIe cables

    I bought this PSU to power my new RTX 3080 Ti that has three power ports, but was very disappointed to only find 2x PCIe cables packed in with the PSU. To buy more cables from Corsair would cost $30 each, and the PSU has the ports to support more connections. Strangely it comes with 3x 8 pin CPU cables, one more than I needed. I returned it and bought the EVGA 850w G6 instead which came with 4x PCIe cables and 2x CPU cables.

      Hi Pete,

      The PSU should include 2 cables that each provide 2x 6+2 connections and should be enough to power the GPU. You can refer to our Tech Specs here to see the included PCIe connectors as 4:

    Great quality product. For the high power item it is, it lacks adequate PCIe ports and cable. but comes with an extra CPU cable.

    This is a great psu, however I am on my second one, mainly because my last gpu killed it by over drawing power.

    They removed the bag the cords came in, removed a PCI-E cable and gave you 3 CPU cables. All while increasing the price.

    The power supply died one week after I installed it, and three days after the 15 day return period expired. Best Buy would not let me return it for replacement, forcing me to go through the Corsair RMA process, and keeping my computer as long as that takes. The power supply was quiet for the 7 days that it worked.
