Check the cable from the strimer to the Lian-Li controller, if I am correct it just needs it changing to one of the other ports, think there is three on there if I am not mistaken.
Hi, the OEM version will perform and function exactly like the retail one minus the box and booklet you get with retail, I have been very impressed with the OEM version of the card you have and it doe's seem to be very of good quality, not had many issues if any with them as far as I know.
Hi, I'm glad you are enjoying your PC but as someone has mentioned your LED strip has come away from it place inside the case, simply take the side panel off and push the LED back into place, it's held in place by double sided clear tape.
Look's like a PCS 6003b case? If so this is not ideal but if you take the case side off and slacken the two black hex screws holding the GPU in and push the card down a tad and then tighten the screws back up. Please report back and let us know how you get on.
