Hey everyone,

I just bought a new mother board (biostar a870u3) and a new processor (amd phenom II x6 T1090)

after putting everything together i find that none of the USB ports are working. (USB 3.0 and 2.0) I have tried uninstalling the driver from device managers, restarting my computer and letting it reinstall on its own. I have tried unplugging the power cord and letting it sit for a whole night. I have tried updating all the drivers to the latest drivers. I am truely and completely stuck you guys are my last hope :(

is it possible that my power supply doesnt provide enough power to the mother board?

I have a corsire 500w PSU
currently i am running:
AMD x6 t1090
1x HD radeon 6850 graphics card
1 500gb HD (no biggy)

would a 500w PSU be enough to support this?
