Connectors and I/O

In total, ASUS equipped the 990FX Sabertooth R3.0 motherboard with five SATA 6Gbps connectors, which have all been natively wired to the SB950 controller. This means you get five native SATA-III ports. Close to the bottom edge of this board there is one M.2 x2 Gen 3 slot, which is compatible with 2242, 2260 and 2280 form factor M.2 SSDs. Having a closer look at the full-sized PCIe Gen 2 slots, we find three PCIe 2.0 x16, one PCIe 2.0 x1 and two legacy PCI. This model is also compatible with Nvidia SLI and AMD CrossFire. Unfortunately there are no practical onboard power- and reset-buttons and there is also no debug LED.



The ASUS 990FX Sabertooth R3.0 motherboard features a total of five fan headers, which is basically enough to provide a punchy AMD system with fresh air. A closer look at the pictures below shows where they have been placed. All fan headers feature 4 pins and support PWM functionality. Therefore it's possible to control fan speeds from within Windows as well as the BIOS.



Looking at the external connectors placed directly at the I/O-panel, ASUS equipped the new 990FX Sabertooth R3.0 motherboard with one USB 3.1 Type-C, three USB 3.1 Type-A, four USB 3.0 and four USB 2.0 ports, one Gigabit Ethernet port as well as an analogue audio panel with optical out. Unfortunately there is no CMOS reset button.
