    Very easy to change out of my computer. It has risen from the grave, and now I can return to playing games. 10/10 would recommend. And with the wires not being attached already made it very clean in the back of my computer. Less wires to find a home for.

    Great 5v/3.3v specs, acceptable power regulation

    Rescued a machine after a power outage. I didn't want to wait on shipping times, so buying online with local pickup is an advantage for Best Buy on these parts. Plus this unit had excellent specs for the 5v & 3.3V power rails, which is important with the amount of USB power required by many of today's peripherals. ALso worth noting, this had all the connections I needed except one, so I went to another online vendor and found an extra Corsair 8 pin>4pin cable to use for the supplemental PCIe power connector on my motherboard, and plugged that right into the second PCIe power port on this PSU. Everything works great! For the record, there's a jumper that can take that 4 pin right off the 20pin main plug from the PSU, but I'm much happier using the extra 8 pin output as it looks cleaner and If you don't need the Amperage on the 12v or 3.3 & 5v lines, be aware that the 650W unit in this line actually has superior power regulation, filtering and clamping compared to this model. I needed the Amps so got this...

    I replaced the 750W Cooler Master that was in my sons computer, with the old power supply, we were getting horrible coil whine under load and periodic shut downs. We installed this power supply and not only is the system much quieter, it’s getting higher frame rates and running cooler under load.

    It's modular design is nice as you can leave out any cables you don't need, which keeps the inside of your PC case neat and clean. It has enough power to drive a dual Xeon workstation without a problem. Only thing I wish it came with was an extra 8-pin EPS 12V power connector, but I was able to make my own. Most motherboards don't need two, but mine did.

    I had a PSU that kept making my pc lose power and eventually caused damage to my motherboard. I never had any problems nor do I have any more power problems ever since I purchased the CX750M. I like how some of the cables are modular to keep the mess if cables to a minimum. It's still holding up to this day.

    My nephew had burned out his PSU on his gaming tower and I offered to fix it for him. After doing some online research, I decided to get this PSU because it is generally considered to be dependable and high quality. The price was competitive at Best Buy so I didn't have to wait. So far, it's been working like a champ. Nice and quiet too.

    Everything works as described, used it paired with a i5 10600k and a 1080, absolutely no power issues at 750W! Remember power supplies are go big or go home. This should support me all the way to a i9 and 30 series card :) This review is 30days after install :)

    My 600 watt power supply kicked the bucket and I needed something more powerful and that could support my custom AMD Ryzen 7 3700x with 32GB of Corsair ram and 2 Radeon GPUs. The Corsair CX750M works great. Has all the modular plugs and voltage is always stable
