4-pin problem ;-;

[Archillect]

I recently bought a rosewell 4- port 3.0 USB express card so I can have more USB slots but I tried booting up but it always says " please install the psu 4 pin power cables to the 4 pin power connectors on your motherboard" not sure what I am doing wrong. As I need the slots to power up a racing wheel and other devices. My setup is as is - i7-4790k asrock h97 atx anniversary mobo

Let me know if you need anything else I just want this to work. ;-;

Ah, so you see the white connector on the back, that needs to be plugged in to a molex cable coming off your power supply, If it isn't those USB ports will not receive enough power to power your devices.

The Molex cable will look like this:

Many power supplies now a days have them in black (looks better) you just need to plug it in.

The current molex has 2 4 pin connectors on 1 cable so I plugged both USB express cards and connected the 4 pin cable to psu but it says please install the psu 4 pin power cables to the 4 pin power connectors on your motherboard

Maybe its asking about the EPS 4pin or 8pin power cable that should be on the top left of the motherboard by the CPU socket.

Alright I've seen to got 1 USB card working but when I try to connect the other USB card with its single 4 pin cable it doesn't even start up my pc ? Any ideas maybe not enough watts ??? My psu is a evga 750b

Not sure why the other one isn't able to work, maybe defective? If you try swapping them around does it work?
