    Greater than one week

    I put this in my gaming pc. You cant go wrong with a gold rated psu made by Corsair.

    Needed an upgrade for my 3070Ti. Wanted something white because even though my case (Corsair 4000D) hides the PSU reasonably well, you can still see parts of it and I didnt want that.

    I’ve been told few times this brand has manufacturering issues and now I had a chance to make sure on my own experience.

    The power supply is very quiet, lots of cables for all hookups.

    Although this power supply was recommended for the specific build i was attempting once fully assembled the power supply completely fried all of my hardware except for the hard drives, so a motherboard/graphics card are completely done

    Switching from a non-modular 450W PSU and this one actually has 9 SATA cable that made it better as I needed more room to power the components inside my PC. So far, it works as advertised and its relieving that this PSU has 10-year warranty from Corsair which I probably will be able to use this until Ryzen 6K series are out lol. The only drawback I can think of is I wish they added braided cables for their high-tier PSUs.

    Excellent product, white PSU with white cables..wish more manufacturers produced other color variants instead of the basic silver/black.
