Epilogue
The Corsair RM750x meets the ATX v3.1 requirements for transient response loads and achieves high overall performance. I would like to see it have lower voltage drops at 12V under transient loads, but it is still far from the respective limits. The ability to adjust the minimum fan speed through a knob located at the PSU’s front side is an interesting feature, providing more control to interested users. This feature offers increased compatibility to the PSU with the chassis that users will choose to pair it with. Another nice feature is the fan failure protection that Corsair implemented in this platform. The fan’s proper operation is crucial and can significantly affect the power supply’s operation. Therefore, it is time to see more brands implementing this protection. I added an extra 0.25 points bonus for every PSU with fan failure protection to push them to do so.
Unfortunately, the MSRP prices of the new Corsair RMx units are higher than the street prices of competing offerings, but hopefully, once the PSUs hit the market, their street prices will be notably lower. All of us want as low prices as possible, but the truth is that brands that employ many engineers to build unique platforms for them also have to pay them. It is not as easy as getting a ready platform from the factory, putting your label on it, and getting over with it. A note: the platforms that the new RMx units use have been designed and developed by Corsair’s and CWT’s engineers and are exclusive to Corsair only, meaning no other brand can use them.

You help me a lot by using my affiliate links, which don’t increase the product’s price. I get a commission from Amazon every time you do it, which can make a difference for me, especially now that I am on my own, working exclusively for my media and not for someone else.
