Does motherboards cpu power supply have anything to do with usb ports ?

Just asking since i dont know about this thing, but i dont get enough power for my usb ports but im curious is it cause of i have 4 pin plugged to the motherboard instead of 8pin ? Or could it be psu cause its getting old( i think it is about 7-8 years old? i bought the pc used from friend and been updating it since, but i wouldnt want to get rid of the psu since its 850w even though i would need max of 650w ) and to add on this it happens especially when i plug my usb hub(has its own power) and it is connected with mouse,keyboard,wheel setup,joystick and one more which i cant remember.

Also here are specs if someone needs it:
MB: Z87-K
CPU: I5 4670K
GPU: GTX 960 STRIX 4GB
PSU: Chieftec 850w-14c
3x HDD
RGBs and stuff 😛

Can you explain what you mean by USB ports not getting enough power? What are you expecting them to do and what messages, results, or smoke do you see instead?

The USB ports gets its power from the 20/24 pin connector on the board not the CPU power connector.

Okay, thanks. So the reason why i ask this is because i do run out of power on usb ports since they start to disconnect reconnect after about 1-2hours and i have tested this many times and proved that it happens when i plug in my usb hub etc on the same time as my other stuff. And im kind of asking is there anything i could do to fix this issue since its litle bit annoying to plug/unplug stuff all the time(also the usb hub has its own power).
