Hello everyone, I'm a new PC builder with a ROG Strix MBO 550-i. I have a pure power 11 PSU, Trident Z RAM, Samsung M.2, and Inwin Sirius loop fans. So far, I don't have a CPU or GPU installed yet—I'm saving for both. I want to test the motherboard and fans to see if they light up and function properly. After installing and connecting everything, nothing seems to work. Is it possible to test without a CPU or GPU on this board? I was thinking those components aren't necessary for powering the board during testing. Thanks in advance for your help! Have a great new year.

You need both a CPU and GPU to run anything on the device.

Nothing will illuminate at all? It could be a total blackout?
