MSI P6N SLI Platinum

The Platinum range is feature filled, but MSI's most high-end product. Today, we have the P6N SLI Platinum, which is based on Nvidia's nForce 650i SLI chipset. Though the P6N SLI Platinum isn't the top dog in the line-up, it's far from being a no-frills SLI motherboard - MSI has opted to kit this out with a large complement of goodies.

The nForce 650i Ultra boards were expected in February and are still due soon, but considering the low price of the nForce 650i SLI and the recent release of the nForce 680i LT SLI, there’s a question of how little these will cost. This still means the nForce 650i SLI is the bottom end SLI chipset you can buy, but does this mean it skimps on performance as well?

The motherboard features very typical MSI Platinum styling with a black PCB, lime green and orange DIMM sockets, copper heatsinks and white PCI slots. Why change a formula that works?

There isn’t a particular theme for the board, but everything is coloured in a way that isn’t at all garish and still lets you know that every port and plug is different. The IDE ports are yellow, the SATA is purple, the Firewire pin-out is green and as I just mentioned, the memory slots are orange and lime green.

The whole board is decked out in solid aluminium capacitors apart from those that surround the sound codec, but that isn’t particularly important to the overall performance. Solid aluminium capacitors feature an “organic semi-conductive electrolyte” that increases the life and power delivery of board in general since the capacitors are often the first things to die.

The memory slots are coloured according to channel rather than according to where you should put the memory. This is a traditional MSI trait, that is different to virtually every other board on the market. Instead of putting the two sticks of memory in the same coloured slots like you would elsewhere, you now put one stick in green and one in orange, keeping the alternation.

A copper heatpipe travels from southbridge to northbridge then another joins it on its journey to the power regulation components. They are angled out of the way of the PCI/PCI-Express cards, but the 8-pin 12V power connector is placed right in the corner of the 90-degree turn making it really quite awkward to get the plug in and out. In addition, the placement means that the cable has to be contorted to a route across the motherboard, between the CPU heatsink and heatpipe array.

Included is a 40mm fan for the northbridge for additional cooling. It comes with a couple of tiny thumbscrews and sits neatly over the top of the heatsink, out of the way. The downside is that this little monster runs at an incredible 8500RPM, so if you absolutely have to use it then at least attach it to a fan controller and tone down its speed and noise. Thankfully, you don't need it providing your case has some airflow, or your CPU cooler forces some air over it.

Other ports and sockets around the board are very well placed, however. The ATX power socket, both IDE ports, all four SATA ports and the pin-outs for USB and Firewire are all placed around the edges of motherboard for easy access.

There are only four SATA ports from the southbridge since this is the older nForce 430i MCP and MSI hasn’t included an extra controller for additional internal ports. There are however, two IDE sockets to provide legacy support for those who still use IDE hard drives or need to use a ton of optical drives. Both sets of IDE and SATA ports are covered by Nvidia’s MediaShield technology.

MSI does include a single eSATA port on the back of the rear I/O powered by a Silicon Image Sil3531 chipset for extra connectivity, which is a nice touch for this price range. Despite that fact this board can be had for a bit under £100, it still has plenty of different connectivity options.

Only one Gigabit Ethernet is provided by Realtek's RTLB211BL. This is a physical layer (PHY) attachment to the southbridge. It supports FirstPacket technology, but there is no Teaming support since there isn’t a complementary port.

Sound comes via Realtek’s ALC888 codec, which offers ten DACs for 8-channel 192KHz/24bit High-Definition audio and two separate stereo channels for the front panel outputs. The two stereo inputs feature acoustic echo cancellation, beam forming and noise suppression technologies. It’s capable of up to 97dB playback and 90dB recording SNR and has an onboard front panel and S/PDIF pin-out is provided, as well as rear I/O connectors.

Three PCI slots are included, of which two are still usable when SLI is enabled with dual-slot graphics cards. A single PCI-Express x1 port has also been placed above the upper most PCI-Express x16 slot so that it's always usable. The PCI-Express x16 slots have a big enough gap between them to allow for enough airflow, without having the bottom slot so close to the base of your case that your graphics card acts as a vacuum cleaner.

MSI still uses a classic mini-PCB flip method to select between SLI and non-SLI modes. This is certainly the cheaper option, but it requires you remove one or both of your graphics cards and have some nails in order to get the mini-PCB in and out.

The four USB ports pin-outs are colour coded so you know what pin plugs in where, which undoubtedly is extremely useful. However, MSI also gave the front panel pin out a very similar colour scheme and, to confuse matters further, has placed them all in the same area of the PCB. The VIA VT6308P IEEE1394a Firewire pin-out is different in that has a keyed green plastic shroud. This means you can don't need the pins colour labelled as you can only plug the supplied PCI bracket in one way.
