Above, you see that the very first slot is a PCIE 1x slot, and then the PCIE
x16/x8 slot for the primary Graphics Card. Quickly followed by another PCIE 1x
slot, then PCI slot, and then PCIE x8 slot for the secondary Graphics Card when
you run SLI. Then a pair of PCI slots below. At the final bottom section, you
find the Floppy connector, if one is still using a Floppy Drive, and a Molex
power connector for increasing the current provided to the slots, not necessary,
but if one uses up a fair chunk of the expansion slots, then a Molex power input
here would be reassuring.

You should have noticed the PCIE Lane Converter card you see above. Flipping
it around configures the Graphics PCIE Lanes between x16 Single-Card config and
x8-x8 SLI Dual-Card config. So if you’re running dual GPUs for SLI, just flip
the card around.
