    This unit works great, and has been powering my rig for over a month now. Wattage meters shows its operating at the expected input, and the modular cables made it really easy to install. I would recommend this unit or the rm1000i if they’re available.

    Running a Radeon VII, AMD 3950x processor, 64gb ram and several drives and most of the time the fan doesn't even kick it. Even when the fan kicks in, it is almost completely silent. Everything works flawless.

    High quality product from Corsair. You pay a bit of a premium for Corsair products but it's absolutely worth it, especially for a PSU as a bad one can fry your system.

    My only complaint was that the box was missing the screws to use for the PSU, but I had spares. Also the manufacturer offered to send me some when I contacted them about it.

    This power supply is more than capable of providing constant, steady voltages for any computer load, especially over-clocked. I don't drive my vette 150 mph, but it is nice to know I could.

    Probably could have gone with 850W but this power supply can handle the load and more with the recent demands of the new 3k series video cards.

    Psu tester shows all voltages to be exactly where they should be and fluctuations are nonexistent. Silent mode is nice. Just a good strong and stable PSU
