Great Power Supply; Well Engineered; Very Quiet
This Corsair power supply has got to be the best PSU I have ever worked with In terms of Bench Testing a PC. The Modular Design lets you only plug in what is needed to make the system work, which allows you to avoid unnecessary clutter of unused cables unlike traditional PSU's. if i apply the concept of this power supply to building a PC, the Cable Management will be much easier as you will have extra space to store excess cables and can retain the unused cables in your box outside of the case until needed. During bench testing of my new system which contains the following parts: - ASUS ROG Crosshair X670E Hero - AMD 7900X 170 W - Corsair Dominator Titanium DDR5 - Gigabyte Nvidia RTX 3060 12G - Crucial T700 2Tb Gen 5 PCIe M.2 - Micron 500 Gb Gen 4 PCIe M.2 - RM1000e PSU 1000 W I was able to boot, and bench test (Cinnebench 2024) my system and this Unit didn't spin the cooling fan up once for the first 5 minutes of the test. Once the fan kicked on it was so unbelievably quiet. My current system has an EVGA 650W power supply in it and that thing sounds like a leaf blower sometimes. The Corsair PSU functions in a "Zero RPM" state only spinning up when needed and the fan is so quiet you cant really tell when its on unless you are looking at it. I plan on Building y system once my case arrives, and will update my review about installation and cable management, and include a few pictures to boot. I Ordered Corsair Pro Sleeved cables for my build so I will not be using the stock cables in my final build, however I did use them for bench testing and I can say that the stock cables are nice, flat ribbon cables with a durable exterior coating. They are flexible yet sturdy, and can be easily Cable Managed with zip-ties and Velcro straps. Overall first impressions i would Definitely recommend this to people who need a great power supply with intuitive modular cable management for cases like the Corsair 4000. ... show more

Stable, reliable, quality power supply
Color: Black Size: 1000 W Set name: RMe (NEW)
Been using Corsair for my PSU needs for years. None have let me down and this one is looking to continue that trend. Absolutely stable power delivery. Cables are high quality. Powering my 9800x3d and 5080 setup flawlessly since October 2025 now. Absolutely zero noise either from internals or the fan. Came with all cables I could possibly need. Cable length and flexibility are fantastic making them easy to manage. ... show more

A nifty PSU
Color: Black Size: 1000 W Set name: RMe (NEW)
I used the PSU for my side server that I am constructing. I got it and was a bit jelly because of the wires that were shipped with it. The look of it was good, no bells and whistles, but still. On my main PC, I have a 1200W Asus Thor. The 1st Gen. I was tempted to switch that out with this product. In the end, I set up my server. Plenty of power for my Intel Core i9-10980XE matched with my Nvidia 3080. It is very quiet as well. For what I paid for it, I recommend it. No problems installing it. I mean, it's only 4 screws. Cable management was simple: use what you need. It even comes with zip ties. My Asus PSU never did. ... show more

I'd been using Corsair products for a long time and it does not disappoint. I'd only used it for a short while but I expect it to last for a long time.

After over a year of owning it, still working perfectly powering up my rtx 4090 based gaming PC. I have had a few power supplies die right around the one year mark, but thankfully Corsair is a cut above most.
