ECS colour coordinates the DDR2 DIMM slots so you know which slots to occupy, to enable dual channel memory support. The parallel IDE and main 24 pin ATX power connector are to the right of the memory. The nForce 590SLI chipset is situated next to the CPU socket at left.

The ECS PN1 SLI2 Extreme accomodates Intel Core 2 Duo, Core 2 Quad and other models running on a 1066/800/533 Front Side Bus. The ESP12V connector may be a bit difficult to reach, it is located just behind the PS/2 ports in the upper right corner.

There is no heatsink mounted on to the power MOSFETs of the PN1 SLI2 motherboard. If you plan on doing some overclocking, you might want to put some heatsinks on here to keep the power regulators cool. The motherboard is compatible with ESP12V and ATX12V power connectors.
