  • Nice unit, rattles sometimes.

    Its a nice power supply; I haven't had any issues with power draw, no funny smells, stuff like that. The unit rattles/vibrates irritably and VERY loudly at a certain fan speed when set manually, but it's got an "auto" function that controls the fan speed if you choose. When on auto, I haven't noticed the rattle, and I don't believe the fan kicks on audibly. I like that the cables are flexible and seem to be nice quality. It allows for much easier cable management and a nice looking setup.

    Psu is quality, runs 13700k and a 3090 without issue. Fan is quiet or silent. Oem cables are nice and can have combs added to tidy up looks.

    I got this power supply for my gaming PC and it's absolutely fantastic! The cables look great and it has zero issues pushing my hardware (not too surprising considering this is a little overkill for what I'm running) I absolutely love it!

    My son's computer kept crashing. I was advised that this power supply was a good brand. My son has not had an issue since. Price was reasonable, product works great.

    Replaced my nearly 10 year old RM 1000 with this one for my new build and couldn’t be happier. The other one was still working when I replaced it. Corsair has upgraded the cables that come with the PSU. They are no longer in those awful woven sleeves that don’t bend. Much easier to route the new cables.

    Have no complaints. Been using Corsair power supplies for over 10 years and have had no issues with them. PSU is quiet and have had no issues powering a 5090 and a 9800X3D

    Broke my motherboard. Customer service for Corsair is online chat only. Resolution was to send everything to them and wait almost two moths for them to decide if they would compensate ANYTHING and your stuff would be discarded at that time. I’ll never buy Corsair again. After two premature failed AIOs, 2 failed mice just outside of warranty (meanwhile my logitechs have been going for 10+ years) and a failed headset dongle… now this… pass

    This currently powering my main setup . plenty of connections easy to use with plenty of power for future upgrades . If I was to purchase another Power supply I would definitely look at the corsair shift series ... The cables attach to the side on those ..

    Upgraded to a new graphics card and i had the older rm850x series. I bought the newer model that had the newer 16pin 12vhpwr built into the power supply so i didnt have to use an adapter. Thought i might as well upgrade to a high wattage too. So far, works just as advertised.

    This little beast powers my new gaming rig in 2025. I don't skimp on PSUs, whereas with some other PC parts you can truly afford to go cheaper. Peace of mind achieved.

    Powers my build. It has no issues and its really quiet. Corsair products are reliable from my experience and it has a 10 year warranty from Corsair so that eases my mind although I hope ill never have to use it.

    I've used Corsair power supplies in every build for the last 10 yrs. They've never let me down. The modular construction means you only use what you need, lessening the clutter of your case. If you want the best power money can buy then Corsair RM100x is for you.
