Emtek is a South Korean NVIDIA board partner. Their custom designs are often used by other brands, such as Palit. This company now has a blower-type RTX 3090 model which is surprising as they do make 3 fan cooler designs generally.
The graphics card features a semi-custom board design. It is clearly based on the NVIDIA reference board for AIB with dual 8-pin power connectors but those connectors have been replaced with a special connector for a daughterboard. Some AIBs have been putting dual 8-pin power connectors or extension cables, which were then routed through the cooler which wasn’t a very elegant solution but it worked fine as cables were hidden under the shroud always.
Emtek has opted for a different solution which in this case means a secondary PCB exclusively with two power connectors. This allowed Emtek to rotate the connectors by 90 degrees and move them away from the main board. It just seems strange that the company went through so much effort for a single graphics card. What is even more interesting is that the company would rather spend time and resources on this daughterboard rather than use NVIDIA’s innovative 12-pin power cable.
