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...

Great and large power supply.

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.

I'm an avid user of my PC, it is almost always on and used in a gaming setup. I've had some shorting scares in the past where no power would go through due to a bad surge protector, but after making sure all electric charge has left the PC this thing always bounces back.Tl;Dr this thing works great and in the worst case can handle direct power surges without notable damage, multiple times.
