USB ports not working on first boot

[Will_49]

So I finished building this gaming pc and I booted it up for the first time (no monitor) and the fans in the case didn't light up or turn at all, this concerned me and I tried to test the USB by charging my phone, the USB seems to be putting out no power. I don't know how I'm going to use the bios. Please help, anything is appreciated.

If you haven't attached a monitor (and therefor, can't see a display), it may not be POSTing correctly, and that's why you're not seeing any USB power. I'd wait to judge until you attach a monitor.

Thank you so much, I discovered O left out one of the pci-e plugs after I looked up why it wouldn't post. Thanks for your time Barty1884
