Perfect so far with a couple unique features
I installed this unit on 10/22/24, so it has only been in use for a couple days. It has been perfect thus far, and I doubt that will change since Corsair make some of the best power supply units available. I think some of the features of this power supply worth considering includes: Cable connections on side of power supply - this makes the cables more accessible than the traditional location on the back of the power supply. This is probably more intended for a dual chamber PC case, but works fine in a 4000D. Miniature power supply connections - the connections on the power supply size are about half as large as the connections for motherboard, GPU, etc. I'm not sure what the purpose is for this besides making it easier to add/remove cables, but it is a cool feature. The only "con" if you would like to call it that is the lack of braided cables. Regardless, the supplied cables feel durable and are not too stiff. I like what I see so far and think this is a great option for 1000W power supplies.

Works well and matches Corsair white case builds
Works well with the new Corsair Frame 4500X case and has modular white PSU cables to match white PC builds. The vent pattern is different (small triangles) than the newer 3 point vent designs that Corsair uses.

Side-Mounted connectors is a game changer!
The Corsair RM1000x Shift is one of the best power supplies I’ve worked with. The fully modular design and side-mounted connectors make cable management much easier, especially in the Corsair iCUE Link 3500X case. We installed this PSU in two gaming rigs, each with 10 fans total, including the 3 fans on the liquid cooler, and it’s handled the load effortlessly. I’ve been disappointed in the past when I purchased products from the same manufacturer expecting them to work well together, but not this time—everything just worked. What really sets it apart is the Shift side-panel modular layout. It gives you better cable routing options, especially with the PSU shroud making it tighter if not for the side-mounted connectors. No more wrestling with cables coming straight out of the back—this layout just makes sense. Overall, the RM1000x Shift is a great PSU for clean, high-performance builds. The modular flexibility and efficient power delivery make it well worth the investment for anyone building a PC.

Side access = Game changer
Fantastic as always with Corsair power supplies. The addition of the Shift lineup really is the one upgrade every pc power supply has needed since they first started doing modular wiring. Having the cables come out the side, readily accessible when installed in the case is just massive QoL improvement and I will NEVER fiddle with my fingertips trying to line up a cable again.

Solid, High-Quality and Whisper Quiet
Really impressed with this unit. The build quality is excellent—both the unit itself and the included cables feel premium and durable. Performance-wise, it’s been rock solid and, best of all, it runs quiet as hell. I barely notice it’s on, which is a huge plus in my setup. The only downside I noticed was the labeling—it could definitely be clearer. It took a little extra time to make sure everything was plugged in correctly, but once it's set up, it runs like a dream. Overall, a fantastic product that I’d recommend to anyone looking for a quality, quiet unit.

Buen diseño, tamaño de cables dificiles de conseguir.
Usa cables especiales mas pequeños, no lo recomiendo… a no ser que te guste el loselo u necesites este por ser lateral.

Excellent psu
Never knew about sideways PSUs until I saw this. Makes installing into a case much simpler. This uses Japanese parts so it's on par with super flower. Very quiet. Never hear it.

Awesome PSU for my PC
Item is as descrobed and it matches the PC case I have, 4000D Frame RS ARGB. I love it. The only thing I wish was different is the power cable color. I wished it was white as well to match everything else.
