I am installing an Asus P8Z77-V LK ATX LGA1155 in an Corsair 650D ATX Mid Tower Case.

Someone else on this site had this issue, namely "OK, I bought a Corsair Obsidian 650D which comes with 2 USB 3.0 front connector; however, these USB 3.0 connectors in the case only provide a USB pass-through cable. I have seen several USB 3.0 to 20 pin adapters, but I want to get people's opinions. I really want to buy the best solution for this problem. I can't believe that after paying $140 for this case, I get such type of connections instead of the proper 20 pin USB 3.0 connector to the motherboard. In advance, thanks for everyone's help here."

I guess I have the same problem but don't understand the explanation of the issue I just might have. Is this USB 3 port passthrough a problem with my setup and could you please explain why this is an issue?

Thanks.

I have a Corsair Obsidian 800D, the larger version of the 650D. The passthrough cables were required by some older motherboards that did not have on-board headers. For compatibility purposes, many cases model 3.0 front panel connectors as simply an extension cable and then include another extension cable to connect to the back panel (pass-through) or a 20 pin header to connect to the motherboard. If they were to model the panel as a 20 pin header, it would be unusable with many Intel 6 series motherboards.

The best solution is to use a 20 pin header if your motherboard supports it (it does). If the case does not come with the necessary header (mine didn't), it can be purchased at almost any computer supply shop for a few dollars.
