    • Side-Mounted connectors is a game changer!
Size: 1000W
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. ... show more

    • Solid workhorse and the side cables make easy access in tight PSU areas
Size: 1000W
Review Image by FastRedPonyCar FastRedPonyCar
I've got this in my Phanteks X2 and it fits nicely and the side mount cables don't interfere with the rear panel. PSU fan is completely silent and easily enough juice for the 12700k and OC'd 5080. Having a dedicated 12 pin connector for the GPU is nice.

    • Perfect so far with a couple unique features
Size: 1000W
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. ... show more

    • So nice not to have messy hanging power supply cables (that are not required) in our builds.
Size: 1000W
Over the past few years, this is the second "modular" power supply we've bought from Corsair. This design sure beats the design of old power supplies with dozens of wires hanging (many of which were never put to use.) Incredible amount of current (power) available to power massive multicore CPUs, incredible modern graphic processors, huge amounts of "RAM" memory and giant solid state "drives". ... show more

    • Solid, High-Quality and Whisper Quiet
Size: 1000W
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. ... show more

    • Power potentes y prestaciones únicas.
Size: 1000W
Esta es mi tercera compra de este producto. No hay quejas, sin duda uno de los mejores power supply para PC. Por lo general uso esta marca para mis ensambles. Sin quitar méritos a otras. Creo que la línea shift es una de las mejores innovaciones que tenemos hoy en día.
