THIS POWER SUPPLY HAS BEEN RUNNING STRONG FOR 5 YEARS WITH NO HITCHES OR PROBLEMS, I WILL DEFINITELY BE BUYING FROM THE SAME BRAND WHEN UPGRADING MY PC IN THE FUTURE

    • Been running it for nearly 6 years straight with almost 100% uptime, no issues.
Color: 80 PLUS Gold Size: 850 Watts Style: RMx (White) Pattern: Power Supply
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 ... show more

    • Served 5 years, died a hero
Color: 80 PLUS Gold Size: 850 Watts Style: RM Pattern: Power Supply
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. ... show more

    • Buy Corsair for the Warranty-With an Important Piece of Information
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... ... show more

    • Active use since 2021, still no issues.
Color: 80 PLUS Gold Size: 850 Watts Style: RM Pattern: Power Supply
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. ... show more

    • La mejor inversión!
Color: 80 PLUS Gold Size: 850 Watts Style: RM Pattern: Power Supply
Decidí comprar esta fuente porque me canse de colocarle fuentes mas económicas aunque digan certificadas terminaban dañándose por algunos bajones de corriente, y la ultima vez comprometió mi tarjeta madre. Con esta fuente todo ha sido diferente realmente vale toda la pena la inversión, me hizo dar cuenta que no se puede escatimar en la fuente de poder de tu equipo, después de todo es la que se encarga de administrar la energía y si colocas una fuente económica como lo hice yo... Pues te arriesgas a perder el resto de hardware. La instalación se me hizo sencilla y al ser modular me hizo ahorrar mucho espacio de ventilación, ademas la presentación, la caja, los cables, todo era perfecto para hacer un unboxing! 100% recomendada! PD: Aun conservo la caja solo porque es hermosa XD que buen packaging ... show more
