Best Low Power Graphics Card without External Power Connector in 2019

Power Consumption is one of the most important factors that many people take into account when buying a graphics card. Almost all powerful gaming graphics cards require external power from the power supply in addition to the power supplied by the PCI Express x16 slot. These gaming graphics cards require 6-pin or 8-pin PCI-E power connectors from the PSU for their working.

Most of the Mid-range graphics cards uses 6-pin PCI-E connector and high-end graphics cards use one 8-pin or both 6-pin and 8-pin or two 8-pin PCI-E power connectors. Obviously you need a good and powerful power supply for graphics cards that needs external power from the PSU. Also the PSU you are buying should have sufficient number of 6pin and 8pin PCI Express power connectors. This can be a problem for some people who don’t want to change their power supply but want a good powerful graphics card that can run latest games at 1080p and does not require external power from the PSU. There are some mid-range graphics cards available in the market that are quite powerful and they do not need any external power connector from the power supply. Here in this post I am going to provide you the list of such gaming graphics cards with no external power connector. All these below mentioned graphics cards have power consumption of 75 Watt or lower because they draw their power from the motherboard PCI-E x16 slot only that can provide maximum of 75W of power.
