Don't cheap out on your PSU

Reviewed in the United States on October 24, 2021

I'll leave the technical reviews to other more knowledgeable peeps. But from an end user perspective, Corsair is the way to go. All my builds have used Corsair PSUs and Ive never had a problem. Not only are they function, they also look great in the case. I do wish ALL the cords were cloth covered as standard, so that they all match.

Don't second guess Corsair. People saying you can get the same thing cheaper? Sure. Go ahead. Go cheap on your rig. Expect the same customer service too. No brand has provided me the reliability of Corsair. And their customer service is spot on. If something goes wrong, they replace it quick as long as it is a product defect. I've been using them for years and no problems.

Wire leads too short.

Reviewed in the United States on August 9, 2021

Wire leads too short to do proper case build. Too short to be able to hide and route properly out of sight. Love Corsaire however really think they cheapened out on the electrical leads. Possible Pandemic cost cutting?? All I know is both my older Corsaire APUs came with a nice upgraded material bag for leads as well as a Thermaltake APU I purchased included the same. Now not important in grand scheme, however I think it shows Corsaire is cutting costs. This came with leads and wires in clear plastic bag instrad of reusable pouch like others. Bad move Corsaire!! Don't care about clear plastic bag however give us wire lengths of which can be long enough for proper instalation hidden within a case as is expected and proper. Seriously considering returning and buying higher wattage Thermaltake. The best has been dethroned!! Very much a shame!! And yes the consumer notices.

Energy Efficiency and Noise Level

Reviewed in the United States on August 15, 2022

Size: 850WVerified Purchase

This is the first PSU I ever bought for a PC, and first time installing one in a new case to move my build over from an old. My old PSU was one that came with my pre-built PC which was 500w. It started making some grinding and humming noises for a while and I also upgraded my cooling method for my CPU. I originally had a Thermalake CPU Cooler which I hated because it always got so hot. But I had to upgrade my PSU because my old one was not giving enough power. My RGB Fans and my Liquid Cooler RGB Lights would either dim or turn completely off and sometimes the PSU would get even louder like it was working a lot harder to keep the power flowing which caused a lot of performance issues. I. Love. Everything about this PSU, it's so much quieter, my computer is performing like new again, and all of my lights are staying on with no issue. I took online advice and made sure not to go cheap with this kind of thing because one cheap psu, if it's bad, it can go from cheap to expensive if you know what I mean. Your entire PC can fry which would make every component unsalvagable which means replacing the entire thing!

My old PSU has been making the noises at least for over a year, I didn't think anything of it. I kept up with cleaning and maintaining it every 3 to 6 months to make sure dust never accumulated enough to cause issues. I'm still fairly new to this PC building thing but as far as my experience with this PSU so far, it's great, it's quiet, and it made my pc performance so much better. Take the advice like I did, don't go cheap with something like this. You won't regret it. The heart of your pc deserves the best for its lifespan.

Excellent PSU with all the right features

Reviewed in the United States on August 28, 2022

Size: 850WVerified Purchase

Easy to install and zero fan spin and noise under normal load. You may wonder why the fan does not spin all the time like most of the PSUs and that's because it's by design with new technology. The fittings of each modular cable is nice and firm. Packaging is well done with all the required cables and ties in a bag. I have this installed in my BeQuiet case powering my ASUS Rog Strix X-570-e gaming motherboard having 32GB RAM, a fanless GPU that uses big heatsink, Bluray player and couple of SSDs. My whole setup is noiseless unlike my previous build that's 13 years old and having noisy fans. Not a gamer, and using it for daily stuff and streaming. Rock solid PSU giving plenty of power. Don't try switching cables with other PSU brands because you will have voltage issues, etc. Stick to brand specific cables. Good luck!

Typical Corsair; works well.

Reviewed in the United States on August 13, 2022

Size: 1000WVerified Purchase

Ever since Enlight became harder (then impossible) to source modern power supplies I've been using Corsair with no issues and this is no exception. I _never_ have problems with any of them, be it with voltage quality/stability, long term durability, noise levels or anything. This is the largest one I've gotten yet, and it's no different than the 650/750/850s etc I've used in the past.
Modular cables (a main attraction for me) are great as usual, but be warned that they are NOT the same as all models of Corsair modular supplies.
My only complaint is that this one, for some reason, is oriented the opposite of all previous supplys with the fan facing up into the case with no way to flip it... This is an issue for me as I use a specific model, also Corsair, computer case for all of my builds (I picked up a dozen years back on clearance when the local Tiger Direct closed) uses a bottom intake and filter system for the power supply. This renders it effectively useless of course.
It's a minor inconvenience as I'm sure that's probably only a small percentage of cases that have that versus not, but it's still sort of irritating as I've *never* seem another supply oriented that way.
Never the less, top notch.

Good PSU, but awful packaging and cables

Reviewed in the United States on August 2, 2022

Size: 850WVerified Purchase

I honestly don't have much to say about the performance other than it seems to work and will most likely fit my needs for a while. However, one thing I noticed was that the packaging is really bad. Before this PSU I had an EVGA G3 550W and it served me well til I wanted to upgrade my GPU. People said that corsair was better than EVGA so I went with them this time.

But when I opened the box I saw that the PSU was protected only by cardboard and the cables were in a non-ziploc plastic bag. I spend $130 and you give me THAT? The EVGA packaging was WAY better. It had foam protecting the PSU and actual cloth bags for both the cables and PSU itself. What gives? This has nothing to do with the performance, but it shows how much they care. I don't know if I sound like a karen when I say this, but this lack-luster packaging is enough to drive me right back to EVGA.

Also the cable for the CPU was almost too short, in a 4000D, a CORSAIR CASE. I am not about to buy cable extensions for something so trivial. Just make the cables a little bit longer. The cables were more than enough for the EVGA PSU.

Overall, it's a fine power supply, but the packaging and cables bother me too much to give this 5 stars.

Excellent 1000 watt power supply. Very versatile!

Reviewed in the United States on September 2, 2022

Size: 1000WVerified Purchase

With all of the different modular plug in wiring harnesses for ATX/CPU/PCI-E and SATA/PATA this is an awesome power supply. My new motherboard requires the ATX and two CPU power connections and this power supply has more than enough connections for that need. I have not heard any noise level from the cooling fan.

The modular connections make it so you don't have a bunch of wiring hanging around that you don't need.

Perfect for rtx 3080 strix

Reviewed in the United States on September 5, 2022

Size: 850WVerified Purchase

Works perfect for my ROG rtx 3080 strix. This card is very beefy and requires 3 6 pin connectors. The PSU does not have 3 direct connects for this. So you will have to daisy chain one of them. So far I am having no issues at all. My prior PSU would shut off when I would stream intensive games. Now it’s all working perfect no shut offs!

A Power Supply is a Power Supply, Right? Think again.

Reviewed in the United States on July 24, 2022

Size: 850WVerified Purchase

Higher end power supplies are not like regular power supplies. Usually these go in gaming rigs and the nice thing about these is the design. Only use the cables you need and enjoy the quiet operation and the built-in protections. While this power supply provides a whopping 850 watts, You might still have to do some home work and make sure it will provide the power you need for the individual branches, whether that's PCI Express, CPU, Mobo, Storage devices, USB, SATA, etc. Those different areas may require 12, 5, or 3 volts in + or minus variations. Like all power supplies, each is limited to how many watts of power it can supply for each need. So be sure to check your requirements.

That said, this power supply met my needs perfectly and I highly recommend it.

This Corsair RM 1000x Power Supply is the Cat's Meow! You won't hear the Meow though. It's as quiet as a church mouse.

No issues

Reviewed in the United States on August 22, 2022

Quick PSA for stupid first-time modular PSU users like me: Clip in cables before you install it. I made the mistake of installing it before putting the cables in, and I had to take it out and put it back in. Had minor coil whine for the first day or so of use, but that went away, and it runs basically silent. Besides that, no issues running my 3080, I7-11700 system.

Great PSU, and great upgradability options

Reviewed in the United States on July 5, 2022

Size: 850WVerified Purchase

I decided to go with the Corsair RM850x after seeing the positive reviews for Corsair power source units. I also had some friends recommend them due to longevity and trustworthiness.

The fully modular feature is nice in preventing unneeded cables floating around in my tower. The 850 watts is also perfect for upgrading when I decide to switch out my GPU in the future. I haven't noticed any noise thus far, and after about a month, everything is running strong. Set-up and directions, even for a first time builder, were relatively painless with some time and research.

I think it's important to remember to not cheap out on your PSU. This thing powers every other component, meaning it could completely ruin every other component if its some unreliable brand. So stick with someone like Corsair to give you that peace of mind, and definitely research what wattage will work best for your set-up + potential future upgrades down the road.
