> 3 dayEasy to install being fully modular. Even with 30 series Nvidia GPUs requiring those weird 12 pins. I ended up going with the rm850x because of power needs. Solid device for sure

> 3 dayGreat power supply for the price, lots of room for future upgradability, if youre not on a tight budget I HIGHLY SUGGEST buying an aftermarket pair of cables from somewhere like CableMod as the stock ones are super difficult to bend.

> 3 dayWorked perfectly. Fixed my burned out antec PS. Shipped fast. Cables supplied were ample and just fine for me. No excessive stiffness as noted by other reviews. My pc is not a show piece it is a workstation

> 3 dayAn improvement to the old design - smaller size 150mm and have 10 yrs warranty. Flat cables is a must for good cable routing. Time will tell if its durable and reliable than my 5yr old seasonic x series.

> 3 dayThis is by far one of the quietest ATX power supplies I have ever purchased at this power level. It is small and the modular cables are very space-saving!

13-06-2025If you’re looking for a solid reliable PSU that’s not too expensive, this is perfect. Fully modular so you can purchase custom cables if you choose, and sturdy build quality.

> 3 dayI bought the 750w from EVGA. It tested positive and when I installed, nothing worked. I returned it and bought this. Guess what? It works. Switching to Corsair from now on. Very good brand you can trust.
