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!
