    This PSU was purchased to replace a dead unit in a rack of servers. Install was easy and the PSU is very quiet and cool. I have had no issues with it and for the price it was an easy decision.

    This is a great "middle-of-the-road" PSU; It can handle most builds without power issues, so going for higher voltage isn't usually necessary Had my previous PSU literally catch fire and die after years of solid service and dialy use, right before I had to log on to work. Best Buy had the curbside pickup ready to go so fast.

    I bought this for one of my customers who's PSU went out, and I hadn't realized at the time that it was a modular power supply. It was a pleasant surprise. As Corsair is a solid manufacture of computer parts, I highly recommend this unit.

    Not much to say. It's just a PSU. But one thing about this one is it's modular. It comes with plenty of cables that you attach as needed so no extra clutter in the box. Definitely get a modular PSU! Oh yeah...Corsair has a great rep too.

    Best power supply i have bought yet. Its quiet cables are nice. Cables are long they are also flat. I have no issues with this power supply. I can route the cables from the other side of my computer tower and still have room to spare.

    Turned on my desktop one morning but it didn't turn on. Nothing worked. Fortunately, I was able to correctly diagnose the problem as a dead power supply. Did an Internet search for reviews and eventually settled on the Corsair CX750M, which I found at a competitive price at Best Buy. I found it to be easy to install, and I had my desktop up and running in about an hour. Overall, it's an excellent power supply, and it's super quiet!

    This being a semi-modular PSU is a nice feature. Keeps the inside of the case less cluttered and makes cable management easier. I bought this after realizing that the other PSU I had purchased did not have the right connectors for my GPU so I just got this because it was in stock at my local Best Buy and I didn't want to wait for one to be delivered. It's a little expensive and from what I've heard from other reviews online, the CX series doesn't have a great reputation but I've had no problems other than some audible coil whine in a few applications. Overall it's a good PSU and time will tell if the reputation of this series is deserved.

    Replaced an old Corsair 750w PSU that aside from not being modular was almost the same exact specs. That PSU lasted almost 7 years before giving up the ghost so i figured going with the same brand would be an okay choice. Does everything I needed it to and is fairly quiet.

    I bought two for use in a mining rig I built. These are very nice power supplies and run well. They are quite and run cool. They come with heavy duty power cables which is very nice. The modular connection system makes it real nice for management of cables and there are plenty of connectors to power everything one needs. I’m running 7 cards and have it split where one supply runs the motherboard, SSD drive, cooling fans and 3 cards. The other runs 4 cards.

    I bought this power supply simply because it’s modular. I hated the look of trying to hide unused cables in a corner of my case. More than enough power for my system and graphics card.

    I needed to upgrade the power supply in my computer, and had been shopping around online. None of the PSU's looked really good, and their manufacturers I had never heard of. When I saw the CORSAIR - CX Series Modular CX750M 750W 80 Plus Bronze ATX Power Supply for only 124.99, I knew that was the one I wanted to purchase. The box it came in was clean and sturdy. The power supply itself was solid and weighty with clean lines and quality internals. All the cables were neatly wrapped. Installation was easy, only needing a Phillips screwdriver to lock it in. The modular system allowed me to choose and plug in the cables that I needed, making the space inside my computer case much cleaner and organized. Way better than the rats nest of unneeded cables crammed in with the old power supply. After everything was plugged in I switched on the power and I was astounded on how quiet it was. The old power supply sounded like a blow dryer on high and only delivered 600 watts. The Corsair was so quiet, and it is at 750 watts. Heat output is minimal; I could barely feel any warmth coming out of the exhaust fan. I have had it over a month now, and no problems whatsoever. This is a great power supply, and I highly recommend it.

    Easy to use and and easy to install. Detachable connecting cords help keep down clutter in the case. I like having the ability to add other items at a later date without having unused cords right now.

    This unit is modular, which means you only need to use power cables for the components installed in your PC. This makes for a much cleaner install. It runs very cool and very quiet! A great value!

    I prefer modular supplies to limit unneeded cables lying around. This is not totally modular but enough that it worked for me. It is happily powering my Windows server 24/7 and doing it quietly.

    The modular capability of this PSU is what interested me in and the rock solid performance and low power usage (only what you need) is what has me sold. I would highly recommend this PSU.

    For any budget pc build, this is the power supply for you. The semi-modular design helps to minimize clutter because you can put in the cables you need and disregard the rest. The two cables that come built into the power supply are very nice sleeves black cables that look very nice. This is a great value compared to others and it wont diapoint you.
