Insanely quiet and powerful, i have never heard this things fan once. Cables are also a nice braided black although they are quite tough out of the box so you may need to bend them back and fourth before your build to make cable management easier. Best power supply for the value!

Gives a good supply of power. Absolutely no drop in voltage and runs very fast. The integrated fan cools it very well and helps it to run very efficiently and cant help but say enough great things about this power supply and its modularness. Channels really well with its technology.

Power supply is very clean looking, came with plenty of cables, and so far seems to run quiet while handling gaming very well. Using to power a i7-8700k, msi z390 gaming plus, 4x8 corsair vengeance lpx 3600, msi gtx 1050 ti gaming x 4g, and a plethora of rgb fans.

Solid PSU that delivers stable power to a set of 4pin & 4+4pin CPU power plugs on the motherboard and allows for plenty of options for overclocking. The modular design is also ideal for cable management and air flow, plus it's just easier to deal with.

Bought this for my new gaming PC. Has enough juice to support everything I throw at it (RTX 3090, i9-10900k, numerous peripherals / some audio equipment).
Plenty of power cables, easy to set up, no problems with heat or anything.
Works great.

Great PSU. This was for my son for his first PC build. Corsair is a good brand and this psu is performing very well. Install was easy. Fully modular so he only needed to plug in what he needed. Helpswith wire management by not having wires you dont need.

Modular design and up to 750 watts means you're set for the foreseeable future unless you wanna do something crazy like Crossfire/SLI. The only issue I had was with my PC case (the cords are thick, and my case has almost no space to hide the excess length).

We needed to upgrade our power supply to handle our new 3070 and Best buy offered the most competitive options in our area. The RM750 was very easy to install andbhas plenty of power now to handle future upgrades to my sons pc.

Solid power supply! I've used Corsair for my last 3 power supplies of 5-year builds and never once had a failure. The RM750 runs quiet, too. Modular means that you can keep your build clean of any unnecessary excess/unused cables. Highly recommend.

I originally had a EVGA 750GQ paired with my 3080FE GPU / 5800x CPU and my PC was so loud while gaming. It had very noticeable coil whine. I decided to try out a Corsair PSU since they had an amazing warranty 10 years! EVGA only offers 3 years with their PSU. After switching out my PSU my PC is now whisper quite at full load. I have had this PSU for months without any issues. The fully modular cables don’t look bad either. I would certainly recommend this Product. I actually bought a second one for my other PC since I liked it so much. I hope this review helps anyone on the fence about this PSU.

This power supply does it all.
750 watts is the sweet spot to easily power a high end system, with room for upgrades if needed.
Full modular is nice for a clean look and easier cable management.
I always trust Corsair to provide steady clean power to my PCs

Supplying power and all.
Side note, if you are using a board that needs a 4 pin (12 V) plug, this does not come with one, nor do I think it supports it. Luckily for my system it wasn't required, but if you do plan on using that extra CPU power then look for another power supply.

When I first built my PC I settled for a cheap 550W bronze certified cooler master power supply. That lasted me about 2 years and then my PC started making a weird noise when playing games. I didn’t know what it was and then I remember I cheated out on my power supply. I spent the extra money on this monster and it was well worth it. My PC is running very reliable and the noise that was coming from my PC was from my power supply unit. Don’t cheap on that part who knows what could have gone wrong if I hadn’t swapped it out for this one

Corsair never fails to deliver. PSU, is easy to install and is modular so of you don't need the wire you don't connect it ridding your case of all the wire spaghetti and giving better airflow behind the scenes

Starting looking at PC parts around mid March, so that I could have a project to work on during COVID. When the time came to look for a PSU I was a little disappointed that the shortage in supply made PSUs more expensive and hard to find. Once I saw this Corsair though, it was a no brainer. I wanted a sleek look, no mustard and ketchup cables, no non modular, a great size, runs SUPER quiet, and comes from a reputable brand. My only gripe is that the cables aren't sleeved, the only one that comes sleeved is the 24PIN, as a result, I will be buying white cable extensions. Still highly recommend!

Does a great job powering my current build (3080 FE, ASUS ROG Strix Z490-E, i9-10900k). Runs nice and silent without getting hot. Haven't done a deep dive into the efficiency yet but the ratings are solid.
