So I'm about to buy a new pc, but my motherboard information says that it supports two 19 pin usb 3.0 connectors (asus M5A97 R2.0) AND my case says it has a 20 pin connector? (Fractal Design Define R4) So will it still work just fine even thought it has 1 pin less than the connector does? Or do I need some kind of adaptor between them. Thanks in advance guys.
