Best power supply on the market . It is worth every penny because all your other components are attached to it. Paying a little extra for the peace of mind of knowing your psu won’t fry your cpu, motherboard, ram, storage, or gpu is worth the price alone. Yet this power supply Is still great value if you ignore those facts. It is 80 plus gold certified for efficiency and that has been confirmed through Aris at Hardware Busters. He has his own rating system that also gives it cybenetics gold and cybenetics A- for noise which means 25-30 dbA This PSU has all the ports you could ever ask for. It has 8 ports that can accept CPU/PCIE cables. So you can run up to 7 PCIE cables if you also are powering a cpu at the same time. Thats 14 PCIE 6+2 8-Pin connectors as the cords have the extra pigtail connector. It also comes with 3 (three!!!!) 8-pin EPS cables to power your CPU. These are 4+4 design so you can break them in half if you have a motherboard that needs a 4 pin ( some motherboards will have 1 8 pin and 1 4 pin for extra power for example.) Considering 1 8-pin EPS cable can handle over 300 watts its complete overkill, but still nice to have. Regarding included cables; you get 3 8-pin EPS connectors and 3 6+2 PCIE power cables that all have an extra 6+2 connected via pigtails giving you 6+2 connectors on each cable. If you are confused a 6+2 PCIE cable is just an 8 pin cable that can be separated into two sections one being 2 and one being 6. This allows you to break away the 2 part of the cable if you need a 6 pin power connector. You also get a lot of sata cables, a couple moles for compatibility reasons, and a single floppy adapter if you still are powering those. You will have extra modular ports even if you use all the cables. But this allows you to buy more in the future if you want to start a render farm, do AI deep learning, or even cryptocurrency mining, you can power a lot of graphics cards with this device. Lastly the mag lev fan is another big upgrade for the 2021 model. This all but ensures your fan will last the length of the generous 10 year warranty Corsair offers for this unit. I have never even heard it make a noise, electrical nor fan noise. In conclusion, if you see the price and are hesitant just consider this, you are not going to have to upgrade your power supply anytime soon if the next generation of graphics cards are even more power hungry (leaks show they use even more power than ampere.) Also, with the maglev fan and 10 year warranty, this power supply might last you 15 to 20 years of use and be the last power supply you ever have to buy. Lastly because its 1000 watts you are usually going to be operating at peak efficiency. This is because power supplies get their best efficiency at around 50% of their total rated capacity. So this unit will be most efficient at around 500 watts. Because its built for 1000 watts, drawing 600 watts 24/7 wont degrade this PSU like it would a unit designed for 650 watts. The headroom is good for longevity, silence, and efficiency. Just beware of the size. Its 180mm long. The standard ATX spec says a length of 160mm is standard. And many manufactures actually have models shorter than that. EVGA; for example, has many models that are still in the 750-850 watt range, but are 140-150mm in length. But longer length also means bigger fan and better cooling/less noise. Just buy this if you want a power supply you can use for any build and never have to worry about it failing or if it will last you forever. It will.

I wasn't very aware that my computer was under powered until I installed this beauty. My system started running way better. I would recommend this over some of the smaller models that are closer to the 1,000 watts because it's not much more expensive.

Runs cool and quiet, comes with lots of nice beefy cables. Plenty of power for an RTX 3080 plus extras.

I did extensive research to find a powerful and quiet 1000W PSU, and the Corsair RMx kept coming up in discussions. It powers everything I need in my build and is nearly silent. I love this thing!

Very good power supply. The cords are high quality and very neat. They are plenty long enough for whatever size case you may have for your build. The power supply comes with everything you may need and runs very quiet.

Good power supply. Corsair makes good power supplies and while this isn’t one of their really good ones it does get the job done. I’m currently running a 3080ti, 2080ti, 2060, 1660super, 1080, and x79 i7-3930k on a rampage iv extreme motherboard. All on this one psu.

Great PSU. Loads of cables and gets the job done! Highly recommended if you need 1000W.

It does what I needed it to do. It's modular too so that's cool. Plenty of power and turns on my computer.

I bought it for my 3080 super quiet and of course modular. Plug only what you need.

Excellent PSU. Expected nothing less from Corsair. Running a Ryzen 7 5800x w/ RTX 3080 Aorus Xtreme and intend to overclock in the future. One critique about these PSUs is the larger size compared to other ATX PSUs. Other than that it is quiet, does the job, and modularity is always a plus. As other reviewers have stated the PCIe cables are chunky so I ended up using extensions to clean up the look.

Most of my PSUs are Corsair RMx series. They are decent, quiet, and fairly priced. I do not like the PCIE cables, because they are bulky, but other than that it works well.

Excellent product with a lot of quality, it works very well with good performance and does not make any noise. I recommend it to everyone who wants a quality power supply

Fixed my black screening issue. Other PC components were drawing to much voltage from original power supply. Been gaming on new one for a couple months and no issue as of yet ! Thank you!!

I love it....i bought this pcu about 3 years ago and just recently upgraded my gpu from a 4070ti to a 5080...i had to buy a cord for the 5080 but other than that i upgraded my pc with ease...i definitely recommend this pcu if u want to be future proofed

This charger saved me randomly one day when I was trying to build a pc. I purchased an EVGA and it failed. Then my motherboard we tried failed. It was a mess of a build and this power supply is the only item to still survive a year later. Recommend Corsair power supplys

Looks and functions incredibly well in my high power demanding build! Depending on the case you choose you may want to use a SHIFT series instead, but with the Corsair frame 4000d case/similar it works incredibly well

Power suply was exactly what i needed fits in my build and powers everything perfectly. My 4090 super gpu runs flawlessly. Highly recommend this power spuly for the price.

One of the best power supply, very powerful to power you pc to max capacity.
