Really silent product, look very high quality, however the cable for PCIE graphic are really dumb. 2x cables 2x8pins, so you left with one extension in the air, not super optic. But once hiden, very good product.

i never found a good psu for my pc like Corsair RM1000X 80+ Gold every thing is good .
Powerful and quiet PSU. The cables are a bit stiff and some of them could have been a bit longer for good cable management. But that's if you are fastidious, it's working good as it is.
It can power the GPU with 2 different cables which is nice. It can also support most high-end GPUs and CPUs without an issue, and still have leftover power.I don't get why people complain about the sound. When AAA gaming at 4K60 with an RTX 3070 and an i7-13700k, my PC is pretty quiet (no water cooling) and when the sound ramps up it's just the case fans and/or the CPU fan.
It's very well made PSU and offers enough power for the new GPU generation. Had previously installed an RM750X, which was great and ran absolutely stable.RM1000X has a small disadvantage. In the low load range it produces very slight coil whine, it's really very quiet but you can hear it. Not a problem for me, since it doesn't happen while idling (e.g. surfing, watching videos), but you can hear it in simple games. I knew beforehand that it could happen, it was mentioned in some reviews.From my side but a clear buy recommendation. Price performance is very good with the Corsair power supplies, and there is also a 10-year guarantee.
When installing this PSU I found a critical flaw: the wires from the heat shrink to the connector just do not bend.I have an ATX case THERMALTAKE Versa U21, the graphic gas pedal to the wall of the case is about 2 centimeters. My current PSU has good soft wires, so not much of a problem with that, but the wires from this Corsair...To use this PSU, I need to find a case where there will be at least 10-15 centimeters from the inserted graphics card to the wall of the case.Translated with www.DeepL.com/Translator (free version)
