EPOX 9NPA-SLI is based on the NF4 SLI chipset. It supports the Athlon 64 Socket 939 and can be configured to use 2 x PCI-E x 8 or 1 x PCI-E x 16 for best graphics performance. The rest of the specs are similar to the Epox 9NPA+. e.g. NVRAID, 8 ch audiom, GbE using SimpliPHY chip. There seems to be a cooling fan at the rear of the board to cool down the mosfets and this can be useful during overclocking.
