    It's a great power supply especially when matched with some nifty white sleeved cables :P. This should do the trick for the newer series cards that have yet to come out. Fully modular so no mess, and well its corsair!

    This PSU was DOA, and now its outside of the return window for Best Buy - I work, so this was the soonest I could test this thing and no power whatsoever. All this and a heft price tag, no thanks.

    Had to get an extra pcie cable for the 4090 this only comes with three of them and in the future will upgrade to one that has the 12pin plug in but this worked to get my system going since my 850w didnt have enough pcie plug ins to run the extra plugs

    It does the job but it's overpriced.

    It works. Not a big fan of it though. Got it to upgrade from my EVGA 750 Gold watt psu and the first thing I noticed were the inferior cables. These cables are poor compared to the EVGA ones I had. Very thin cables with only the motherboard cable being braided. All my EVGA cables were braided and that one cost significantly less. Shame on Corsair for cheaping out on cables. The Ultra-Low noise doesn't seem to be incredibly accurate. It's for sure audible but it's tolerable. You definitely do hear this thing during bootup. It makes an audible sound everytime. Overall disappointed and wish I'd gone with a seasonic or evga again (just got it cause I had a corsair psu and pc case), and may just end up returning it.

      Hi,

      Sorry to hear about your experience. The cables are designed to With Zero RPM Fan Mode, this PSU's cooling fan switches off entirely for near-silent operation at low and medium loads. It is normal for the fan to switch on upon power up. The HX1000i allows you to monitor power settings and toggle between single to multi-rail overcurrent protection (OCP) via our iCUE software. For video guidance on setup, please refer to our CORSAIR LAB video: (https://youtu.be/Rt2cokCoOTM). If you have any questions, we'd be happy to assist: help.corsair.com

    Good psu. I returned it but only because it wasnt atx 3.0 pcie5. While they sell a pcie5 cable separately not worth the risk.
