All this should not make "cheap" and fit properly to the tower. Mission accomplished.
Well-designed plug, nothing to buy next, even the power plug is made so that it uses a Molex plug, but in return she provided another! For that alone, it's great!
Usb 3: flow saturating my external hard drive to 100MB / s.
USB2: does its job!
Card reader: Same, no complaints
E-sata, Same again!
On Windows 8.1, all settled in 5 seconds, no drivers, and everything works hyper transparent, no software, impaired drivers, or dintermédiaire.
Check if you have the proper connectors on the other hand (SATA socket, molex, usb 3 19pins and internal 9pin USB2)
All good!
