    I bought this as a gold power supply for my first PC build. It powers an AMD3700, RTX 3070, and a ROG MOBO easily. It was extremely easy to modularly build and fit perfectly into my Corsair case. I think I didn't get the deal I was hoping for at the time of purchase, but I would buy again.

    Was using a TX550 to power a home server. After adding a 10th HD, I started getting errors which was finally trouble shooted either PSU failure or just not having enough power. Enter the RM750. Plugged it in and hooked up the 10 sata connections (yay): the server started up and has been running without a hitch and no more errors. I now have 12 HD’s totaling 31 TB. RM750 is humming along just fine without breaking a sweat. It’s also quite,

    Solid PSU, way more than I need, but it’s difficult to get exactly what you need right now. Seemingly silent at 300-500 W loads

    This was for my first PC build. Only item I bought from BB for said build. I bought the other components at other spots due to 1. Better pricing, 2. Lack of stock of other components. This was the best price for the RM750 compared to other spots. I also wanted to note that this was one of the few components which arrived at my doorstep without a dent on the item's box. Pretty happy with it; clean look, does it's job, and am definitely gonna continue using it when the time comes for an upgrade.

    Although the Corsair 650 had not yet given up the ghost, I figured it's time to replace it with a little more oomph. The old one is 10-11 years old and still works fine! I do expect this unit to last a long time too. It's more than adequate for my needs and a name I trust.

    My old computer kept rebooting so I initially thought it had to be the power supply. After I installed this new one, the issue kept repeating, so it wasn't the problem after all. Long story short it was a bad SATA cable on my main boot drive. Considering this PSU is 80+ Gold certified (and the old one is un-rated), I decided to keep it anyway to proactively upgrade the 9-year old one it replaced, so I'm still happy with the purchase.

    I've had this PSU for a while and its worked like a charm. replaced my old 500 watt unit for this beast. cables could be a little better, but this isn't the highest end and they're what's to be expected. the modularity makes the back of my case look nice, and is just a great thing to have. packaging is nice, in corsair fashion and it arrived very fast and on schedule. i highly recommend this product if you're searching for something in this class.
