Some graphics card measurements

I spent a bunch of time watching videos about the NVIDIA Geforce RTX 3090 Founders Edition  graphics card yesterday. Today I’m going to need to get down some practical considerations of considering what would actually happen when this card arrives. It needs to have supplemental power connections in terms of 2 PCIe 8-pin cables. That should be ok based on my power supply setup at the moment. I’m going to swap out two graphics cards for this one graphics card. That should free up the right power cabling and slot space. However, the card dimensions are another point of legitimate concern. This new graphics card is rather big at 12.3″ (313 mm) by 5.4″ (138 mm) and takes up 3 full PCI slots worth of space. The graphics cards currently in the case take up 9” (228.6 mm) by 4.1” (104.14 mm) and one PCI slot each. Which is much smaller than the RTX 3090 card footprint. My 2018 computer build is based on a Corsair Carbide Series Air 740 high airflow ATX cube case. I’m going to need to get out an actual tape measure and see if this new graphics card will even fit. During the course of doing that I’m going to need to check to make sure those power cables match the right counts for connections. 

I’ll be right back…

Based on my initial measurements the card will fit in the case, but the two power cables are 6-pin not 8-pin cables. That means I’m going to need to go dig out the power cables that came with the power supply and locate some alternative cables to use. I guess some adventure awaits on that front. This weekend I’m probably going to need to uncable the case, clean it, and check the possible alternate power cabling setups. The power supply needs to have the right connection slots and I need to have two 8-pin cables that are long enough to power the new graphics card.
