    Corsair makes quality power supplies. The RMx series uses quality components and this is no exception. Although you’ll hardly ever see it in ur case, it pairs well and matches the Corsair Frame 4000D case.

    Good for the price, it comes with everything that you need. So far haven't pushed it too hard (I have run some benchmarks, which it performed good in), but expect it shouldn't struggle.

    Had to go thru 2 other Power supplies before I got this one because the 9070 XT Gigabyte Gaming OC needs x3 8pin connectors & the other power supply’s only had 2 of them. Also cable management on this PSU is great! I thought about buying cable extensions but after opening the box I was supper happy with how the included cables looked that I did not need to buy the extensions.

    The cables that come with the psu are braided and are some of the best I've used and feel much sturdier than other manufacturers. The knob for manual fan control is a neat feature even though I just leave it automatic.
