Customer Ratings & Reviews

This is a great power supply for when you have 12th or 13th gen Intel chips and an Nvidia RTX card. I'm using a water cooling AIO along with lots of fans and argb lighting. This power supply comes with a cable that plugs directly into the GPU without having to use an adapter for the 12 pin plug. The plugs for the cables are on the top also, so you'll have to make sure your case has space above the power supply instead. With the cable plugs being at the top, it's so much easier to manage cabling. I highly recommend if you're needing to plug your power cables in at the top.

I have been a long-time purchaser of Corsair PSUs. This RM1200x is powering my current build flawlessly and seems to be of the same quality I am used too. I have a 7800x3d, Asrock Taichi B650e, 64gb CL 30 6000 Ram, Asrock Taichi 7900XTX and 12 case fans in a 7000D case. The system has been super stable, and I have had zero power issues. I wasn't sure about how I would feel in regard to the side connections for all the PSU cables. While using the 7000d I have had zero issues and find the side connections very convenient and easy to work with. I think if you had a case with closer clearance between the frame and the case backing/door the side mounting could be a potential issue. The fact that it is ATX 3.0 was important to me. It also has 4 single 8 (6+2) pin pcie cables so I could connect the 7900XTX without having to use the pigtail style. There is a new metric being used that includes a CYBENETICS rating which I don't recall being included in the description. I have included a picture of the CYBENETICS rating for this PSU. I don't care for using words like overkill. In my opinion purchasing key components like PSUs above what you think you will need will always allow for system to function under less strain and also provide for more future upgradability. I would rather save up more money for a build than to ever drop a level on core components such as a PSU. I would absolutely recommend this PSU.

Good PSU, no problems adding after market extension cables. Powers my 4090 and 14900k with ease. Although, with usb headers becoming more and more needed. There are better options out there with them built in.

Corsair quality doesn’t need introduction so, the high outlut plus the new 600 w capabilities make all the difference

Corsair psu is the only psu I will ever use. Always had great luck with them

Side connections make it very easy to install and cable manage. 1200w has plenty of pcie/cpu slots. Have had no problems at all.

I wanted a new P/S, and wanted to never have to worry about 'is it big enough?', and have the cables come out the back. This is big enough, for sure, and the back connectors are a win. This thing sleeps through the heaviest work, would buy again and again.

I would recommend this product to anyone with a high end gaming rig. It may seem like overkill, but its nice to have the extra overhead to limit the power spikes. The design is top tier, and makes one of the more frustrating parts of building a walk in the park. Do yourself a favor, and buy one of these!

The psu has a very solid design with very convenient side plugs which makes making cable changes easy since you don’t need to remove the psu to make changes. Also with the 12vhpwr cable included it prevents needing adapters to use a 40 series gpu. The cables are also very well done unlike some other cables that have a tendency to have weak points at the connectors.

I was looking for a new PSU to power up my RTX 5090 and I came across this one. It stood out to me because of the location of the cable ports. I researched and learned that this would fit my Corsair 5000D case, while also leaving me with plenty of space for my HDD cage. So it was a perfect solution to my situation :) The PSU itself is nice. The cables are like any other psu cables, except they have smaller connections to the PSU, which is interesting. It came with the power cable I need for the 5090, so I was happy to avoid using the adapter that came with the card. So far the PSU have served me well!

Pros: Small form factor and genius design, can't believe that other manufacturers haven't thought of putting the cables facing towards the user, which makes cable management and changing cables easier. Plenty of included cables No Coil whine Quiet Cons The sata power cables are weirdly organized, they don't really work with corsair's own cases (4000d and 5000d) without some brute force

Going strong after 2 years. I have this PSU powering an RTX 4090, intel 9 13900k, multiple monitors along with VR games and it has been flawless.

This has been a great power supply! Fits my Corsair 700D case perfect. has plenty of power running an RTX3080 and four mechanical Hard drives. Very quiet! the connections exiting the side make for much better cable management versus the old style.

Good PSU with solid power delivery right out of the box. Easy to use and connect. Buyers should be mindful that this is a shift model, meaning the connections will be to the side rather than the back. This can be great for cable management but it really depends on your case, so plan accordingly. Would rate 5/5 but the included cables are very stiff and look/feel cheap; probably to encourage sales of their separate "premium" cable kits.

Fantastic PSU. I had all sorts of issue with my rig and an 850 watt EVGA PSU. I couldn't set my ram correctly with EXPO and had to down clock DDR5 6400 to DDR5 5700. My rig would blue screen and crash in COD. I thought it was a bad motherboard. Then I was reading on Asus's site that I should use a 1000 Watt or great PSU for my configuration. All other PSU configurators said I only needed a 650 Watt PSU. I picked this PSU up and it has fixed all my issues. I love love love the side mounted power terminals. Makes install of the power cables a breeze. No more busted knuckles.

This power supply is a beast. Plenty of power for all my computer components. Came with the new power cable for Nvidia 40 series GPU’s. Also very quiet. Highly recommend

This is a solid power supply that suits my needs perfectly. It easily powers my 9800X3D and RTX 5090. It even includes the 12V 2x6 cable for the GPU.

Excellent power supply, quiet, easy to set up. Has all the cables for the latest video cards.

You can’t go wrong with Corsair. At least I haven’t. I have their memory, cooling units, and now I have their top-of-the-line psu. I have confidence why. I turn on my pc that it is going to start up fast and strong. I run 2 video cards, blu-ray player, cd-rw, an ssd, and a hdd. Plus I have a water cooling unit for my gpu. Not a hitch. I would definitely buy this again, if I was building another unit. For sure.

Great for my 5080 build and upgrade later down the line
