    Not much to say, high quality single purpose piece of hardware. Powers my 7900xtx over locked beautifully. My previous 800watt couldn’t keep up with transient spikes, this solved the issue. It may be as powerful as a microwave, but it works well. Came with plenty of accessory cabling and I like the look of the individually textured cables.

    Fits great in a Corsair 4000d AF case and is plenty of power supply for my needs. I really like the fan speed control too, but my only complaint is the hidious cables. Corsair, please start shipping with decent looking cables instead of these with the finnicky cable combs.

    Fantastic PSU. I love that it has a physical dial on the back to adjust the fan speed. I will say that the lack of cord bundling is a bit janky though. The clip system used is much more cumbersome for cable management.
