Looking to buy a samsung 840 evo 500gb but apparently it does not come with SATA cord or power cord. What do i need to get it running? Will it take SATA 6? Is the SATA cord also the power cord? Thanks for any help.
The power connector should come from the power supply; all modern power supplies have a good number of SATA power connectors like this
The SATA cable is standard connector used by HDD and optical disk drives. Yes, you'd like to use SATA 6GB/s for best performance and plug into a SATA 6 GB/s port on the motherboard with a cable that supports 6GB/s. Check your motherboard manual to see which ports support 6GB/s. If the SSD package doesn't include one you can find a set of SATA 6GB/s cables for a few bucks online.

The power comes from SATA power connectors which should be attached to your power supply or come with it (if it's modular).
You need a SATA data cable as well, any will do. You can pick them up fairly cheap.
