Help with SATA cables.

WTJ105 · Jun 23, 2016

Hi,

It's my first time building and I have encountered something weird. My motherboard is Gigabyte GA-H81M-H. When I tried to plug my PSU SATA cables to my motherboard, it seems that my PSU SATA cables were larger than my motherboard's. Did I buy something wrong?

Looking forward to hearing from you.

There are only two cables from the PSU that plug into your motherboard; the 24-pins cable, and the 4-pins cable (power for the CPU).

The SATA cables go from the motherboard to SATA devices like the SSD, HDD, DVD drive, etc,

The manual will explain this.

Sorry for a noobish question, but should I plug all SATA cables or just 1?

WTJ105 :

Each SATA device needs a separate SATA cable.

OS disk (SSD or HDD) --- SATA 0 (make sure this is SATA III capability)
Data storage HDD ---- SATA 1 (SATA III capability)
DVD drive --- SATA 2 (SATA II capability)
Second data HDD --- SATA 3 (either SATA II or III capability)

SATA 0 has the highest priority and should be used for the OS disk (this is usually SATA III capability).

Watch some videos on PC building and you will feel more comfortable with the procedures.

I looked at your motherboard again and yes SATA 0 and SATA 1 are 6 Gb/s (SATA III)

SATA 2 and SATA 3 are 3 Gb/s (SATA II).

Please watch some videos before you start assembling the computer. Pay particular attention to CPU installation and heatsink installation.
