I hope you plan to SLI with your 560 ti if you're getting a 750W psu. If you're not drop down to around 650W. Your motherboard appears to be a Gigabyte and it does mention FX so I will assume SLI with your 560 ti so the 750W is good.
For hard drive, I don't know what that is but your money should be put into getting the Samsung Spinpoint F3 HD103SJ for $60.
I can't even decipher the heatsink either haha. I would go for the Hyper 212+ for $30 or Mugen 2 for $40 instead.
