The motherboard I bought, the EVGA x58 LE, comes with 2 SATA data cables and 1 SATA power cable. I currently have an OEM HDD, OEM SSD, and an OEM DVD burner. So I need to buy one more SATA data cable...and how many more power cables?
Then you just need to buy the SATA data cable. You may as well have the power cables for supper. (They're totally worthless for that system then, since their only real use is to allow an older system to give power to the new drives. That is a new PSU and will have those needed connectors.)
Any brand of sata cable will do.
You might want to get one with a right angle connector for your dvd burner.
Get one long enough to run from the most distant sata component to your motherboard. A bit longer is OK.
From an aesthetic point of view, you might want to match the color of the supplied motherboard cables.
From a practical point of view, I like to use different colors to more easily identify which cable goes where.
FWIW many X58 motherboards will also have legacy IDE capability.
The TX750w has two lines, each with 4 SATA power connectors and two lines, each with 4 molex and a floppy drive power connector. Unless you have an abnormally large number of drives, you will have plenty of power connectors.
