It's interesting how easy it is sometimes for a company to leak their own product information; and this time Asus has gone and spoiled it for themselves by posting the model names of five upcoming boards for AMD's AM2+ socket on their support site.

Let's start with the one that we have the most information about, the M3A78-EMH HDMI. As the name suggests, this board has HDMI output and it's based on the AMD 780G chipset and the new SB700 Southbridge. It features HDMI, DVI and D-sub, as well as Gigabit Ethernet, 7.1-channel HD audio and four rear USB 2.0 ports. It lacks any kind of S/PDIF, FireWire or eSATA connectivity.

However, it does have six internal SATA connectors, thanks to the new SB700 Southbridge. The board also has four memory slots for up to 8GB or DDR2 memory, a single x16 PCIe slot, a x1 PCIe slot and two PCI slots. It also has a very peculiar feature (and we have no idea why Asus implemented it): it's a huge jumper block which consists of 10x3 pins that are used to select between DVI and HDMI. Either this is some kind of new "feature" of the chipset, or we don't know what it is. It will also be one of the first boards that supports Hybird CrossFireX.

You can actually download the manual for this board here, if you're interested. Kudos go to Planet3DNow for finding this.

The other three boards are the M3A78-EM HDMI; we're not sure what the missing H means, but it should be quite similar to the M3A78-EMH HDMI. Then there is the M3N78-EMH HDMI, which we presume is based on the upcoming GeForce 8200 chipset due to the N in the model name, which tends to indicate an Nvidia chipset in Asus's model names. Then there is the M3N-HD HDMI, and finally the M3N-HT DELUXE, but we don't have any real information about any of these boards.

The only thing we know for sure is that the M3N-HD DELUXE will be based on the Nvidia 780a chipset and will come in two versions, of which one will feature Asus Mempipe memory coolers.
