For the slim DVD-ROM in my HTPC I needed a 16-pin SATA connector, the ITX mainboard or the power supply but only 22-pin connection options. This adapter has been the solution to this problem, it worked until I wanted to build an additional hard drive. When really very light to one side of the SATA cable to the adapter disassembled into two parts. CONCLUSION: Who very carefully deal with it, will take place this adapter an adequate solution
