Hi, so this is my first time building a computer and I'm completely lost. Last time I kept up with computer stuff was maybe 2003.
The motherboard came with two SATA 3 cables that I put on the Bluray player (http://i.imgur.com/IId97lz.jpg) and the 2TB HDD (http://i.imgur.com/hzm2wVE.jpg). Do I need to buy another cable for the Bluray thing? Sorry the picture is a little fuzzy, all I have is a phone for a camera. And the HDD, what do I need to buy for that?
You have a modular PSU. That means you only have to use the power connectors that your PC actually needs so you can save space and improve airflow.
You will need 1 SATA power connector each for your Bluray drive, 2tb HDD, and SSD, in addition to the SATA data cables. They look almost identical, however the SATA power connectors are the wider of the two.
As for your GPU, it should have a 6-pin or possibly 8-pin power connector arranged in a rectangular shape. Your PSU should have been packaged with the appropriate cable as well. If not, you can use those adapters you pictured to go from a 4-pin molex to the 6 or 8 pin that will fit in your GPU.
