Next up on our journey is the south bridge. The south bridge of the Gigabyte GA-Z87X-UD4H is passively cooled by a healthy heatsink. Just to the upper right of the south bridge, you will see a SATA power connector. Gigabyte recommends in a dual GPU configuration that extra power be supplied to the PCI-E slots using a SATA power connector from the power supply. This will ensure that plenty of power is available for the GPUs.
