CORSAIR RM1200x SHIFT Fully Modular ATX Power Supply - 80 PLUS Gold - ATX 3.0 - PCIe 5.0 - Zero RPM - Modular Side Interface - White

850x Shift version.Solid, reliable and quiet so far. Installation was a breeze, made easier with the side-on ports. Plenty of room in my Fractal Design Meshify C case. Loads of cables included, most of which I didn't need.

Had a 500W Seasonic PSU before this CORSAIR RM-1000 SHIFT and this looks more cleaner and tight looks. This PSU has the industry standard 80 plus GOLD whereas the old SEASONIC PSU didn't have any 80 plus standard because that's how old the PSU was. It runs cooler and quieter than the SEASONIC and some might say overkill because I just need a 500W so, thumbs up from me.My electric bill is still the same.size wise, I have a GIGABYTE 3D AURORA case It fits in (not really) but I can only manage to fit two screws to secure the PSU and and it's not secure and I cant fit my door because the Type 5 cables from the PSU are protruding , so I need a new case effectively.

Great PSU, works very well. 5 stars!

The media could not be loaded. Overall it’s a great design, makes cables very accessible, however if you have a Corsair 4000D or similar cases it’s going to be hard to put all the cables away. Great addition however is that all cables are flat, makes a clean build.Very quiet PSU works like a charm. Had to swap out rm1000e due to bad coil whine, this one doesn’t have any which is great.

I purchased this power supply after spending a week reviewing numerous power supplies online. This PSU is listed as a tier A high end power supply on cultist reviewsI had recently upgraded my GPU to a 7900xtx and my Seasonic prime 850w could no longer handle the power demands put upon it so needed to upgrade.Due to supply shortages and high prices in the UK currently I decided to go for a cheaper option and so far I am glad I chose this power supply.My first choice would have been a platinum or titanium rated Seasonic supply but this gold rated supply from Corsair is still impressive for the price.Another benefit this PSU has is that it supports the new ATX 3.0 standard and comes with the new 12vhpc cable for when I need to upgrade my current GPU. The unit also comes with enough PCIe cables for any GPU requirement. Mine uses 3x cables. You get 6x cables total with 2x being able to daisy chain with but I don’t recommend you do that and instead use the 4x single 6/8pin cables instead.The unit fits nicely into my PC case without issue however my case is very large. It’s a cooler master cosmos s2 case. Had this awesome case for nearly a decade now.I am very happy with the build quality and the unit is extremely quiet with my PC under full load.I would highly recommend this power supply if your on a budget but you do need to make sure it will fit in your case first as cables are on the side of the unit.

I've been using the Corsair RM850x SHIFT for a few months now, and it's been nothing short of fantastic. The power delivery is rock-solid, ensuring my high-end components run smoothly without any hiccups. The build quality is top-notch, and the sleek design fits perfectly into my setup. The 'SHIFT' feature for real-time adjustments is a game-changer, allowing me to optimize power efficiency effortlessly. The cables are neatly organized and easy to manage, which is a huge plus for cable management enthusiasts. Overall, the RM850x SHIFT is reliable, efficient, and a definite recommendation for anyone seeking a high-performance power supply.

This is an innovative design where depending on the design of your case it may make it much easier to plug and unplug the cables where there is more space under or above the power supply rather than behind it.However in cases where the power supply slides into a slot you may find it won't fit with cables plugged into it. However where it only screws to be back of the case and leaves the side exposed then it should be ok and may be easier to work with if you have limited space at the back of the power supply and it may provide more effective cable management.

I am a big fan of Corsair stuff but initially opted for a cheaper and well reviewed PSU for my latest build from NZXT. After less than 12 months that unit failed, and was the first time I’ve ever had a PSU fail on me. Bought this as a replacement as I’ve never had any issues with Corsair products before. So far so good and love the connections on the side rather than the rear of the PSU. Makes cable management much easier.

ممتاز.

TUTTO OK

The idea of having the modular connections shifted to the side of PSU is awesome. This is the perfect PSU in my opinion.

The Corsair RM1200x SHIFT Fully Modular ATX Power Supply has been a game-changer for my high-demand PC setup, which includes a 4090 OC and other high-performance components. This power supply handles all my hardware needs effortlessly, providing stable and reliable power even under intense loads. Its fully modular design makes it a breeze to set up and manage cables, keeping my build neat and organized. If you’re running a demanding system and need a power supply that won’t let you down, the RM1200x SHIFT is an excellent choice.

Bought the PSU only to find out that the 1000 Watts doesn’t come with a 600 Watts cable but only 450 Watts. Only 1200 Watts model comes with a 600 Watts cable. To get 600 Watts on PCIe cable you need to order another one from Corsair. Complete waste of my time. Returned and refunded.Not sure how to attach image but I have PSU box image that says <=450 watts ATX 3.0.
