It works out of the box. Went with white for the first time and cables have a nice braided sheathing and are a nice contrast to a black motherboard. As usual Corsair quality. I heard the 2020 versions of this power supply may have shorter cables or other cost cutting things done-I cannot verify this, but I intentionally bought the 2018 model of this PSU. Here's the important part you NEED to know. When you search and find "RM 750x", look CAREFULLY to see who it's sold from. Both "Sold" and "Ships" from should be Amazon. None of the other sellers who list this product are authorized resellers of this product and Corsair WILL NOT honor their warranty if you try to save $10 and buy this from anyone here other than Amazon. I was looking for this product and all of a sudden it went $10 cheaper and I thought "cool, it's even cheaper now". As I added to my cart, I noticed it went to one of their vendors to get this cheaper price. I deleted it, and chose the one $10 more that is sold and ships from Amazon. As soon as you get this PSU, register it with Corsair to avoid the potential receipt issue down the road. Don't say I didn't warn you.... I will continue to support Corsair as they make fantastic products and are one of the few companies that stand behind their product (if you follow their rules and purchase from authorized resellers). I had an HX 600 go bad after 9 1/2 years, called Corsair to start the RMA, and about a week later they sent me an HX750. Amazing service. It would have been nice to see the PSU keep on going, but heck I'll take 9.5 years and a newer higher powered replacement. Amazing service. Just an FYI, this is the only failure I've had of a Corsair PSU in about 15 builds I've done over the last 15 years...

I mainly bought this for it's white color and the fact that I only trust Corsair with my power delivery. They've never let me down. I planned ahead with life with this one. I figured that since I will eventually move to a new place and depending on location my electric bill could vary; that I would get a more efficient box being Gold Certified. It being fully modular was a dream come true. I've always wanted one! Weird thing to always want, but it makes a big difference to me! The color of the case throughout all of the cables is white and very clean! I added cable extensions for good looks where visible and no problems there with fitting snug yet somehow easier to disconnect from the motherboard inputs over their other PSUs. Great stuff! One last thing I liked was the included solid, not partly transparent, white zip ties.

Built my PC in early 2019, still using the same computer today. I do all of my work on my computer, and most of my free time is spent at my computer as well. Since building my current PC and using this PSU: - I graduated high school and used this PC extensively for gaming and school work back then - Enrolled in and graduated university, again using this PC extensively for gaming and school work - Spent thousands of hours playing games on it - Spent thousands of hours mining crypto on it - have had probably 99%+ uptime since the day this PSU arrived at my door since i never turn my PC off - Learned basics of blender, video editing, graphics programming, and more Overall, this PSU has worked perfectly for years without a break even though i have done many tasks that are intensive on the CPU/GPU and have high power draw

I'm using this power supply with an MSI Z490-A Pro motherboard and an Intel Core i7 processor. I had previously assembled this PC with a 2 year old power supply, but it couldn't supply the CPU power required. This power supply has all the connectors I need and does it's job very quietly (the system is quite cool). I wasn't sure about the 100% modular connector approach, but it certainly has freed up some space in my case - the reduction in clutter makes both airflow & upgrades easier. I'm having zero problems with this power supply after several days of nearly continuous use. Recommended.

Let me start off by saying, this is an amazing power supply. It served perfectly for five years and would’ve probably lasted a lifetime. When building a new system, I brought this power supply with me. Somehow, I managed to plug something in so wrong that the moment I plugged the system in, I knocked out the power in my house. This power supply took all of that and failed spectacularly, saving every other component in the new system from my mistake. Thank you, Corsair, for making and excellent product.

Haven't heard a bit of noise from this thing. The fan is never on unless my computer is under a full load. It's a quality PSU. Haven't had a single problem with it. The PSU cables are a little stiff, and the PCIe cables for the GPU could be difficult to maneuver based on how many you need.
