Customer Ratings & Reviews

Easy to hook up and get started. Quiet, provides plenty of power.

I've got a RTX 3080Ti (not flexing, context) and an old 750W PSU which raised me a lot of doubts over whether or not it would suffice to run the card, AND to overclock the card afterwards, and upon some research, I found out my system would run at around 700w at full load, so I knew I had to get a bigger PSU to feed the beast, especially during spikes, and so I did, and this PSU was actually smaller than the 5 year old 750W I had! I'm very pleased with the product so far, and I hope it lasts me very long. It has in-line capacitors on some cables, but I don't care, whatever reduces the coil whine works for me. PSA: This being a full modular PSU replacing another full modular PSU, at first I thought the cables were the same. THEY'RE NOT! So to save you a lot of potential headache, heed my warning: Unless you're 125% sure it's the same pinouts, replace the whole cabling going to MB, CPU, GPU, SATA... all of it with the cables included on your new PSU, regardless of brand.

This power supply is a bit longer than a standard ATX power supply but offers Lots of power for use with multiple and/or high end graphics cards. Comes with 3 PCIe cables. Also has two 12V CPU outputs for over clocking. Great choice for gaming or intense use machines but would be overkill for a casual use PC (i.e. web browser or office apps. Gold efficiency rating for lower power use, quiet and a 10 year warranty.

Provides stable power for Ryzen 9 7950 and 6900XT. Easy setup and module allow for custom cables.

Great power supply for the money, and for gaming builds that need a lot of power. This replaced a Corsair CM750X which was great, but didn't have 3 8 pin PCIE connectors that I needed for my new 3070Ti. This was a little longer physically, but it still fit in my case fine. I like that its fully modular, including the ATX and CPU power lines. I've been running it for 2 weeks and put many stress tests on it and its still great. Highly recommended, especially for the cost.

The Corsair RM1000X PSU is a game-changer. Its 80 PLUS Gold efficiency saves power and keeps things quiet. Modular cables simplify setup, and Corsair's reliability is evident. Whether you're a PC pro or newbie, this PSU is top-notch. It's made my computing life easier, and I highly recommend it!

This PSU is very easy to install and comes with lots of cables. Great power too.

I bought this to replace a faithful Rosewill psu. I wanted to future proof my gaming pc, and this power supply for the bill. It’s a little bigger than some but runs great and the modular cables keep my case less cluttered. Really pleased with the product and no issues even after 6+ months of use.

Great power supply for power-hungry setups. The fact that this power supply is fully modular gives you more freedom to how to manage your cables. Pretty good unit for the price as well. An amazing purchase overall.

PSU was easy to install. Came with more than enough cables. Very quiet operation and I am very pleased

I’ve had this for a couple months now. Haven’t had any overheating issues and it’s quiet. Highly recommend this for higher end Gpu’s and future proofing. It being modular too is a big win, no more cluster of cables.

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 pcie drives, a Panasonic Bluray burner and lastly the XFX Merc319 6950 XT graphics card. 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.

Great PS !! More than enough to power a 3080T. Was easy to install in my case and quiet.

Love the PSU. Its bigger than i thought it would be, but i needed the extra power to run my new 4080. No issues with the install, cables are premium as well. Corsair makes a solid premium product. I would recommend to anyone.

Fully modular, well powered, cooled and quiet. Well worth every penny.

Great performance, super easy to install. Fully modular. High Quality PSU.

Fantastic modular psu for a custom system. Very quiet and easily installed into a Corsair 4000D AirFlow Case. The only issue was the hdd cage had to be moved to the forward position in order to fit all power cables. All cables are sleeved and work well. Due to upgrading GPU a higher wattage psu was needed. This replaced a cm750.

Powerful PSU! I love the fact that it’s fully modular and it has all the power you will need to pair it up with high-end components!

Outstanding power supply, silent while powering an overclocked/liquid cooled 13900k and rtx 4080. Corsair is the brand i turn to when i want a dependable psu.

Great power supply. Never had any issues. Modularity is great. Good option for a long term power supply. Plenty of room for high end upgrades and good price
