Do I need to install os & a CPU to use USBs properly on motherboard & case

[Patrick_143]

Im building my first budget gaming pc and I have the motherboard, psu, & ram installed and the wiring double checked. I just need the os(windows 10) on USB flash drive, CPU(i3-6100, storage,& graphics card(rx460). I tested the usbs on the motherboard&case(USB x2 2.0 x2 3.0 but when I plugged in a mouse & keyboard it flashed the caps lock light and the mouse flashed it sensor and turned off. I also plugged in a phone charger and nothing even happens, but when I plugged in a USB to phone it took some adjusting and it worked with the lights& everything. I replugged the USB 2 and 3 wires back in and I checked them and it still has the same problem. Is it because I don't have a CPU, storage or OS. I JUST NEED AN ANSWER

Wait till the build is complete before you test it again. 😀

You cant boot without CPU and trying to test it without components is just asking to cause problems

You mean testing the usbs Without the CPU or the other stuff I listed will maybe cause problems

Well the board will specifically not boot without a CPU, but in general you are just adding unneeded risk by testing things before you are 100%.

Yes you are , you should never pretest till build is complete.

how will you install the os when you can't see anything?

I was just trying to test the USB ports before I got the rest of what I needed
