I have had some dreadful experience with Corsair refurbished PSUs. I bought 3 of them and all three have had problems. AX860i bought from MicroCenter 8/24/2019 dead within a week. Replaced with AX860 supplied by MC. This PSU appeared to operate normally but an attached video card kept black screening. A replacement card exhibited the same problem. Replaced the PSU and the problem went away. Bought a refurbed AX1200i from Amazon in November. By March I was experiencing intermittent shut downs. I had to fight Corsair who told me I have only a 90 day warranty on a $300 power supply. They agreed to replace it with an HX1200.
