Question Only plugging in 24 pin to mainbaord

[PrimalReign]

Hi, I recently got a new mainbaord, the Gigabyte Aorus Elite. It together with the RAM and my nvme arrived together today and l wanted to show off all of my RGB goodness to my dad. Convincing him that I knew what I was doing I only plugged in the 24 pin into the mainbaord thinking this would turn on the RGB on the board. When I turned on the power supply the Mainboard lighted up for a second and then the lights went off again, I tried turning on the PSU again and this time nothing happened. Just FYI I hadn't put in the cpu or gpu, only ram and nvme because that was the only thing that had arrived and for the last hour or so I have been anxiously searching around the internet trying to find an answer to :
"Have I fried my Mainbaord?" which is why I ended up here.

I doubt you hurt anything.

That's fantastic to hear, sorry if this is a noob question but I just had to be 100% sure because otherwise I couldn't have gone to sleep knowing that there might even be a 1% chance of having fried something.
