cant pay me to buy a refurb psu, 1 in 5 regular 5 year warranty psus will die wit continuous mining use i have found in 2 - 4 years on average, brand doesnt matter, rossville quarks, evga platinums, xfx plats etc etc
u have 10 psu sitting here waiting for waranty returns along with 30 amd gpus lol
waranties matter folks, a refurb waranty is 1 year, just enough time for it to die and leave u stuck with a brick
theres a reason why most platinum psu vendors offer 5 to 10 year waranties
But it's Corsair.
I would understand if it's some smaller company like bequiet, cougar, chinese, or whatever is cool nowadays. I believe they also have a reputation to maintain which is why they won't just sell items that are easily broken. If only i needed a PSU, i would get one.
