I have GeForce gtx 750Ti ddr5 graphic card green edition. In which no additional 6pin pci-e power cable is required. I want to know that , can I install it In my motherboard which supports only ddr3 ram , it has a slot for GPU but I am not sure that a ddr5 graphic card will work or not. And also it has 450W power requirement, so should I use 450W psu or more Watts PSU, what should be it's efficiency. I also need help about the cables and how to install it in my motherboard properly.
Pop it in and see if it works but i believe your PSU mite need to be replace 600W is a good number your 450W mite be to small.
well i personally like a 550W PSU minimum because in the the future if u want to upgrade and add on more parts u dont have to worry about a undersized PSU.
