MIght have blown the PSU, and/or MB...(assuming nothing bent/shorted in USB port, and was temporary short)

Logical step would be to try a known good PSU of sufficient wattage first...

so you are telling me to change the PSU??

I'm not telling you to do anything...

But, your computer now does not work, and, given a possible full short that likely occurred at the USB port, you will only be able to confirm the current symptoms are a result of a possible bad PSU by swapping it with a known good one, or, alternatively, testing yours within a known good system.

If you swap the PSU and it now works fully, that would be the most ideal of outcomes, i.e., not complicated, not expensive, and only a 15 minute ordeal of swapping PSU and cables.

Good luck.

you want to do some dedbug steps. one clear the cmos see if the mb anti short tripped. if there not post from the gpu or onboard video port. turn the power off. unplug the usb cable if it was the front case ports. see if the mb posts. if there no post take the pc down to onboard video and one ram stick if there no post there look to see if there any fault led on. if there are none pull the mb see if it post outside the case. on testing make sure you have a known good video monitor that works. also pull all of the usb devices even the keyboard and mouse. if there no post it can be mb or power as posted before. on the mb look for and smell for melted cpu chips. you may have dead shorted the usb chipset.
