We often spend time looking over Video cards on NewEgg, eBay and others. We do this to check prices and availability etc.
Low end cards like the GTX 1050 and GTX 1050 Ti are mostly 7″ length logic boards. We often see dual fan coolers on them that extend the card length to 9″.
We have a Gigabyte GTX 750 which has a single fan cooler. We also have a EVGA GTX 1060 which also has a single fan cooler. The GTX 1060 is a 120W TDP card and the single fan cooler can easily handle the thermal load with the fan at 50% or more.
Now when we see less demanding cards like the GTX 1050 and GTX 1050 Ti with larger coolers, this seems like overkill. It also means they do not fit the µATX chassis very well.
We expect dual fan coolers on 150W and more demanding cards as these are heavier and more robust and are designed for the higher thermal loads. Cards like our EVGA GTX 660 Ti and the Asus HD 7870 are both better off with the dual fan coolers.
Recent video cards are more inclined to have 8-pin power PCI Express connectors instead of 6-pin connectors. This is easier to manage as almost all high-capacity power supplies all support 6/8-pin connectors.
Our AX860i can handle any power pig video card we may have. So for the HD 6970 has held the top spot for the biggest TDP of any card we have used. The PSU is overkill with the GTX 750 but we use all classes of video cards as our uses do not all have RTX 2080 Ti cards installed.
