    I was going to go with a 750 watt and used the 850. The reason was to have the extra power supply to the ATX for the GPU and other peripherals. The supply works really well. The only issue was my case has an intake/exhaust on the bottom side. So I flipped the PSU over so that the fan was on top of the vent. Doing so made the sticker on the back of the PSU upside down. I had to peel it off the back and flip it over. Corsair needs to leave the stickers off and let the customer use them as needed.

    It works well this cable has this imperfection though it’s like ripped and stretched in this spot I already put the power supply in my system. None of the other cables look like this it runs so I’m not gonna return it but if it bothers, you should probably check your cables more thoroughly than I did

    This powers my Ryzen 7 5800x, MSI 240mm AIO, and 3070 Ti with zero hiccups. Hands down the best brand for power supply’s and never had any issues in the past and so far. 850w is more than enough for a high tier build. 10/10 recommend this product.

    Switched from an EVGA BQ 750W to this power supply and it was worth it. It is very quiet under load with my RTX 3070 and Ryzen 5 5600x and silent when idle to light load. Would definitely recommend it.

    Everything is perfect, my only complaint is that I don't like the cable that powers the graphics card, I would prefer it to be clean, without that ugly extra connector.
