Different from the 680i SLI, this engineering example did not use south bridge to north bridge heat pipe system. 780i SLI only have heat sinks+fans. The north bridge big heat sink are cover both SPP and BR04 chips.
780i SLI use black PCI Express 16x slot. Different from 680i SLI's two black + one blue. We believe in the retail version 780i SLI will still using two black + one blue PCIe X16 slot and heat pipe design.

There is no difference between between nForce 780i SLI's power module and nForce 680i SLI's. Both of them are 6 phased. Every phase have one R50 and four Mosfet. Because of this, we once thought the 780i SLI mobo is only an another version of 680i SLI.
though they really simaliar to each other, we also can find some difference if we look carefully.

1、Because of the BR04 needs room，so nForce 780i SLI is canceled one PCI Express 1x slot.
2、 nForce 780i SLI using NF570-SLI MCP chip，but nForce 680i SLI is using NF590-SLI MCP chip，the only difference is their name. They have no huge difference in their functions. We will have a detail description in our later review.
3、nForce 780i SLI using two one-digit-DEBUG LED，but nForce 680i SLI have one two-digit LED.

4、The position of the front panel connector and clear bios jumper are different.
5、nForce 780i SLI canceled one 4Pin D type 12v power connector beside the memory slot of the 680i SLI.
Our review is coming, someone testing the mobo said that the 780i SLI's funtion are quite different from 680i SLI. Pls keep tuned.
