Also i want to add more power cables to power my hardrives WHAT SHOULD I BUY !!?
You buy internal SATA cables from a store like Micro Center. You can also buy adapters that plug into your hard drive power supply connectors and then your SATA drives. But you could also buy a new power supply that has multiple SATA power connectors
Most all motherboards have like 6-10 SATA ports on them, meaning you can connect 6 sata devices (hard drive or dvd drives). Your power supply is what gives you sata power cables. Your psu needs to have the cables already built into it, since the psu has to have the power to actually power all those devices, so it only comes with cables of what its capable of powering. There are 4pin molex adapters which allow you to use a 4pin molex to power sata devices. So you would need to buy sata cables to connect drive to motherboard, and your psu needs to be capable of powering them. You may need to buy a new psu.
