    Such a high quality product. High grade materials used in this power supply. Clean power delivery to my computer. I've never had any issues with Corsair power supplies and that continues to remain true. Ising this to power a 7800x 3D with a 4080 OC edition TuF card. Plus a 4tb nvme, 7 case fans a nd a 360 aio.
