I have a Corsair AX1200 that I purchased in January 2011. It's still going strong in my Corsair Obsidian 800D case (purchased the same time). I believe the motherboard has been upgraded 4 times, maybe 5. The first video card in that case/power supply was a 8800 GTX times 3 for triple SLI and has been thru a 580 x2, 980 x2, 1080 x2 and currently a 2070. The power supply has been on 24 hours more often then not. It suffered thru dozens of blackouts and brownouts.
Storm is rolling in. Let's see how it does...
