I recently built a pc with an rtx 5070 ti and had a 750W but it wasnt powerful enough to even run the gpu or even save my windows installation. After swapping to the RM1000e everything worked perfectly and still continues to be. You also cant forget the price value, at the time of purchase it was literally a 20$ difference in the 850W to the 1000W so obviously easy choice, long story short if you need a powerful PSU that i personally have still never heard a noise from then this RM1000e is the product for you!

Great power supply overall. Install was straightforward and everything felt solid and well built right out of the box. It’s been running quietly with no coil whine or issues, even under load. Cables are clean and easy to manage, which made my build look much better. Definitely happy with this purchase and would buy it again.

Was easy to setup fully modular allowed me to connect all my fans with ease

Great psu, would reccomend, got mine powering a b850 mobo, 9800x3d, and a 5070ti. Granted i couldve votten away with the 850 W but i wanted room to upgrade. Would reccomend, maybe do the 850 if you're not running a 5080 or 5090 tho.

Great Power supply, great for my 5080 and ryzen 7 combo!

Excellent psu for gaming I love the style and performance with hard components

Great product. Love it. It’s Corsair. Easy to install and I like how compact it is. Much smaller than all my other PSUs I had. Fits most of the cases. The only complain I have is only 2 Sata ports. Usually, all other PSUs have at least 3 and that’s for 750watt or less. Corsair supplied only 2 Sata cable which included only total of 6 SATA connectors. I tried to use EVGA connector and had issues powering on the unit. Please use only corsair type of sata connectors. 6 Sata connectors is not enough. Now, I have to purchase a separate cable from Corsair which is out of stock now. Really?

Easy to build with just like any other filling modular PSUs. But I love the new 12hpw connector that allows you to easily connect RTX 40 and 50 series GPUs

I built my PC and put in Corsair RM1000e with 8 Fans Three Monters. I needed lots of Power Its been working great

It's a great PSU. I love the dedicated tax port and cable for my GPU. It works great and gives it a cleaner look. It was easy to install and has great quality for the price. I see myself using this PSU for years to come.

I upgraded from the 4070 super to the 5080 and needed a bigger PSU. So far everything is working great!!

Running a 14900k and 5070ti. Plenty of power left for future proofing.

Great psu! Perfect for my build! 10/10 would buy again.

Great power supply. Came with all the connections I was needing

Corsair really makes nice PSU's and this one its just so nice. The cables are super nice quality and they look so good in an all white build!

I love how every cable is made, also the quality of the ps is great

It looks good, the cables have a clean look, BUT at some point after putting load on it it just makes this ticking noise which Corsair said they had fixed but it's still doing it.

It was faulty and i had to return it. Had to get the x version the 2nd time.

Will be returning because of static noise and random shut downs if your build is similar to mine I would just try to get something else. 5080/9950x3d

Very pleased with the product and the Best Buy experience. I had stopped going to BB years ago over some poor experiences. Holiday season 2025, I snag a deal on this Corsair RM1000e PSU for a build upgrade I was doing. The PSU is excellent. Smaller and lighter than my 10 y/o EVGA 750G2, but seems to have very good build quality as the EVGA's did for their day. The cables were great to route and manage. Lengths worked great for routing inside of a Lian Li Lancool 217 using the default internal 90-degree. That was the biggest reason I purchased this PSU. It was powerful and well-built, but also compact enough for this configuration. At 140mm in length it would also work well with the smaller Lian Li Lancool 207 as well. I wanted a little more space and went 217. The fan is quiet even under heavy load, but seems to exhaust hot air effectively. No issues at all, very impressed. The Best Buy experience was equally good. Folks were friendly pointing me in the right direction, getting me checked out quickly for an online order with in-store pickup. The price was great and local pickup was awesome. I am glad I gave them a chance again. Well worth my time, will buy from them many more times if this is how my experience will be.
