Does this comp have the ability to use a GTX 1660 card if the old card had no power cord? GT 1030 GPU is the old card
The answer to your question is will depend on the requirements of the card. The PCIe Interface is the same as the GTX 1660 cards, but some do need the PCIe power connector that you mention. You should check your PSU to see if there is a power connector stored inside of the case. Here is a small, but powerful, card that only requires 300W: https://www.newegg.com/gigabyte-geforce-gtx-1650-gv-n1650ixoc-4gd/p/N82E16814932151
There are three main things to consider: 1) the length of the card. The article tells you how to measure the space where the card will be installed with space for good airflow, 2) the wattage to run the card properly and 3) does the card require any PCIe (1x6-pin, 1x8-pin or both) power connectors. Also, the PCI Express x16 Interface should match the motherboard's PCIe x16 slot, 2.0 or 3.0. The cards are backward compatible. The specifications of the motherboard don't mention the version. I believe that it may be 3.0. You can check to see if it is listed on the motherboard.
