Uninstalled GPU while psu was plugged in

[Carter fields]

Hello,
So I made a really big mistake I usually always unplug the psu but this time I forgot, the computer was shit down (so I assume much power wasn't moving through the gpu) this is a brand new build antec 550w 80 plus , i3 4170 3.7Ghz , R9 380x (the card I took out ) the computer still runs good and I'm not having any issues , I did 3D mark fire strike and got 4500 ish (with my Gtx 660) since I use cuda for some applications.
So did I damage stuff or is this an it either works or doesn't thing?

No power goes through the computer while it's shut down, but taking out the power-supply ensures no electricity transfers to the components. It's a good practice/habit to remove the power cord, and if you say nothing is wrong, then it's fine
