I purchased this to replace my older Cooler Master semi-modular PSU that rather unceremoniously ate itself. I did not spend a lot of time carefully weighing my options as I needed something same day to get my computer back up and running.My primary criteria for a new PSU was 1000+w due to the anticipated higher power demands of 4000 series cards. In retrospect this may have been more than I needed as the actual specs for 4000 series cards were not quite as demanding as had been initially anticipated. That said, PSUs last a while, so it's probably not bad to overbuy a little.Other factors in choosing this PSU included the fact that it was fully modular rather than semi-modular making cable installation easier, the 80+ gold rating, Corsair's decent reputation for ... MoreI purchased this to replace my older Cooler Master semi-modular PSU that rather unceremoniously ate itself.

The internal fan seems to be pretty quiet, at least compared to my other fans in the PC.The best part of this was Microcenter's selection of available parts for purchase same day. Had I been stuck going to [competing big box retailer] to get a same day PSU, I'm certain I would have been stuck buying either a really low quality PSU at a mediocre price or a massively overspeced PSU at an exorbitant price. Good product, good service, there's nothing here not to like.

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 dbAThis 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 ... MoreBest power supply on the market . It is worth every penny because all your other components are attached to it.

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.

Fantastic power supply. I was having issues with my supernova G5 850 watt power supply when trying to play Steelrising and A Plague tale on my AMD RX 6800 XT at 4k the screen went black, so I decided to get this power supply and install it in my computer. I went and tried both games out on 4k and test it to make sure it works and it did, not black screen was running smoothly. I believed my older power supply couldn't handle it and was drawling to much power.

I'm a bit torn on purchasing this, even if it was on sale. Upgraded from a 750W EVGA G2 to help power the 11600K + 3080ti and while the core features of it are well made, I expected more out of a higher end product with a higher price tag. First gripe is the PCI cables that have the same options as lower capacity PSUs: 6+2 pin that are daisy-chained with no other options. The description mentioned 3x 8-pin cables which is what I expected (or even better, 3x 8-pin and 3x 6-pin) which isn't a big deal apart from the daisy-chained (all of them are like this). Why do manufacturers continue to do this when the PCI spec is to NOT do this? Next up is an oversight when looking at compatibility with their own product, specifically the 4000X. Trying to plug in their SATA ... MoreI'm a bit torn on purchasing this, even if it was on sale.

Why do manufacturers continue to do this when the PCI spec is to NOT do this? Next up is an oversight when looking at compatibility with their own product, specifically the 4000X. Trying to plug in their SATA cable into an SSD mounted on the back of the motherboard tray is difficult to say the least, since the cable has a right-angle connector which is pointed in the opposite direction of the drive, making it have to loop back over and around (their mounting bracket isn't reversible). Lastly are two small details that I would expect out of a 200$+ PSU: a little bag to keep the accessories and spare cables in. They came in a disposable plastic bag. Not sure why this is missed when several other manufacturers include them with most of their modular PSUs (like the EVGA G2 which was much cheaper). Another example is the sleeving, which is exactly the same sleeving as their TX (semi-modular, more budget PSU) model. Overall, I wouldn't pay full price for this but the quality of what counts is clear and a lengthy warranty goes to show that Corsair has the confidence to back their product up.
The psu was overkill for my current build but I planned on slowly upgrading it as I could with my current job and just wanted the extra wattage incase I ever need it. The unit is pretty quiet and runs quite well. The cables however were stupidly stiff due to the tape type material toward the end where they decided not to fully thread the cable. The plug-ins within the unit are also very difficult to plug in or take out, and are misaligned with the holes. While the stiffness makes cable management difficult even within my 4000x, its still a great power supply. I was able to get it at a discount or I wouldve just called it in at the 850. If you can look past the cons, and the price is reasonable or lowered at the time, get the unit. Maybe an aftermarket cord pack ... MoreThe psu was overkill for my current build but I planned on slowly upgrading it as I could with my current job and just wanted the extra wattage incase I ever need it.

Maybe an aftermarket cord pack could fix the issue but they would probably still have to be corsair as the unit clearly states to only use corsair or lose the warranty. Oh and since I bought this and told the dude running the live stream of that night, I got him to sniff the power supply he was reviewing and lick it. Regarding my build, I am using the built in graphics of the 11th gen intel i7 as I am still in highschool and only make 10 an hour. Plus its my first build I know the cable management blows I was to excited about testing it out and seeing if I built it correctly.
When it comes to power supplies - they are generally looked over because they don't really do anything cool other than boot up your system.Performance- Gold, fully modular, and Ten Year warranty? It doesn't get much better than that. As far as the fan attached to it, it might as well not even have it because I never hear it and the PSU does exactly what it is supposed to; disappear and never know it is there other than to turn your PC on and off.Value- For a gold 1k watt modular PSU, Corsair comes in right at or under the market median as these are ALWAYS on sale here at BestBuy for deals better than you can get elsewhere and at Corsairs own website. The cables that come with it are great and slim.

When I think of a PSU and computer brand I can trust I go straight to corsair because they haven't failed me yet as they have amazing customer service and even better products so you rarely have to utilize their +A customer service.Conclusion - From an easy-to-track out naming scheme to be a reliable switch, corsair has really killed it with this PSU. It is hard to get amped when it comes to PSU's as they do a thankless job that rarely gets any attention except for when it ISNT working. I couldn't recommend this PSU more and I have had 4 or 5 Corsair PSUs now with zero issues.
This does what it says and is stable. I'm running a RTX 3080 ti, which this should be more than enough to handle. I don't hear any fan noise as it has never gotten hot enough for the fan to turn on.Some feedback for the Corsair. The first concern I have is the length of the cables. The motherboard cables barely fit my compact mid tower case, the Corsair 4000D, while traveling through the case's built-in wire management. They are both Corsair after all. I also wish the cables were more flexible at the ends. There are large non-flexible sections at the end where the cable transitions to the mesh sheathing. Would also be nice if they included extra, short cables for the motherboard and GPU for folks that want to use strimmers. Then again, if they just included ... MoreThis does what it says and is stable. I'm running a RTX 3080 ti, which this should be more than enough to handle.

This is a problem with all PSU manufacturers, so not a problem particular to Corsair, but something they could do to differentiate themselves in the market.

I build and fix a LOT of computers, and I've seen power supplies fail in just about every way imaginable. The things responsible for converting wall power into precisely controlled DC outputs take a lot more wear and tear than people generally imagine. Capacitors wear down with age leading to voltage drops, cooling systems seize up and start grinding, I've even seen a couple short out and catch fire. But I can count the number of Corsair power supplies that have broken down on one hand - which is why they've been a regular fixture in my personal builds for over a decade now.Yes, it is a somewhat pricey unit. But Corsair's quality control and engineering alone is worth the premium given that a PSU failure can easily end up frying every other part in a system. And ... MoreI build and fix a LOT of computers, and I've seen power supplies fail in just about every way imaginable.

But I can count the number of Corsair power supplies that have broken down on one hand - which is why they've been a regular fixture in my personal builds for over a decade now.Yes, it is a somewhat pricey unit. But Corsair's quality control and engineering alone is worth the premium given that a PSU failure can easily end up frying every other part in a system. And the RM1000X has everything you need for a high wattage modular unit. The cooling fan is quiet even at high RPMs, voltages are solid and high enough that the system should be able to remain stable even as the parts begin to age, and the modular cabling system means you don't have to deal with excess bulk for your system which could lead to added strain or damage that could lead to shorts. I picked this up for my home VR rig which is running an overclocked 12th gen i7, a 3080, and a whole Christmas tree's worth of lights and I fully expect that I'll still be running it in ten years' time unless standards change or PSU power draws get high enough that they require a whole new PSU.
So far the PSU has been a great replacement for the EVGA BQ 850 I had been using on my Threadripper build. I purchased this as after adding more storage drives, case fans and most importantly an AIB XFX 6950 xt, i started experiencing power gremlins and spontaneous restarts while gaming that happen when running out of power. This Corsair RMX has fit the bill and has no issues supplying enough current for my bloated workstation/gaming rig. It powers a wnd gen threadripper mounted to an ASUS x399 board, 8 sticks of DDR4 memory, a 280mm liquid cooling system with push/pull 140mm Corsair ML series RGB fans, 3 Corsair 140mm case fans, Phanteks case RGB lighting, an HDD 4 drive RAID array, another 8tb 7200rpm storage drive, 4 SATA 1tb Samsung SSD's, two WD SN750 1tb NVMe ... MoreSo far the PSU has been a great replacement for the EVGA BQ 850 I had been using on my Threadripper build.

On top of that, 10 USB 2.0 and 3.0 ports are in use as well as 1 USB-C port. It remains seemingly silent when rendering or gaming, though the liquid cooler fans spin up a fair bit under heavy load so you wouldnt likely hear it anyways.
