MSI K9A2 Platinum AMD 790FX Motherboard

Article Index:   

In mid-Q4 2007, AMD released their 790FX, 790X and 770 chipsets, the final pieces required to complete their Spider platform.  As the backbone of the new platform, the 700 series chipsets were designed with new feature sets to take full advantage of the Phenom processor's capabilities.  With up to 42 PCI Express lanes, support for four-way graphics, and lower power consumption then previous chipsets, AMD delivered a competitive new chipset to back their new CPUs and graphics cards.

In November, we took a detailed look at the Spider platform coupled with a Phenom processor to see how it compared to its peers.  In the end, Intel still had a leg up on AMD in terms of overall performance, but the new platform was impressive.

Today, we're going to take a look at the latest 790FX based motherboard to hit our test bench, namely, the MSI K9A2 Platinum Motherboard.  Built around AMD's 790FX chipset, the K9A2 Platinum brings four-way CrossFire capability, support for HyperTransport 3.0 and PCI Express 2.0 while MSI adds additional customizations to help raise the board to "Platinum" status.  Whether looking to upgrade the foundation of your current Athlon based system or want to go all out for the full Spider experience, MSI thinks it has a solid candidate for your consideration.  Let's find if they're correct in their assumption, shall we?

MSI complements the K9A2 Platinum with a solid collection of extra components to help take full advantage of the mainboard's features.  The package include the customary Quick Installation Guide, User's Manual, and a poster sized Quick Guide for a detailed overview of the motherboard main components and layout.  There is also a Drivers/Setup CD that includes all necessary drivers needed for proper functionality.  The package included four SATA cables, an 80-Pin IDE cable and a single Floppy cable.  MSI provided two Molex to SATA power adapters, a two-port USB bracket and a single-port FireWire bracket as well.  Lastly, a custom I/O shield is provided (not pictured).
 

     

 
An item that we are seeing more and more of lately are adapters for connecting a case's Power and Reset Switches, and Power and HDD LEDs, as well as custom plugs for the board's additioanl USB, Front Panel Audio, and FireWire headers.  These make it much simpler to connect the individual plugs to an adapter outside the case, then plug the whole assembly into the mainboard in a single motion.  Rounding out the package are two CrossFire bridge connectors.
