Connect the first modular SATA Cable

Start with the first SATA power cable.

Make a Label that reads SSD-HD2&3

This tells you that this SATA Cable feeds power to both the SSD drives and HD2, HD3.

Fix the label next to the SATA connector that goes into the Power Supply Unit.

Your Power Supply can accept up to 5 modular SATA power cables.

They are arranged side by side next to the large Motherboard Connector on the top row.

Use the slot marked green in the picture below to plug in the SATA Power Cable labeled SSD-HD2&3.

Plug in the 4 SATA power connectors to the components from the back of the case.

Connector #1 = HD 2

Connector #2 = HD3

Connector #3 = 850 EVO

Connector #4 = 850 PRO
