Just bought a computer from Best Buy and wanted to upgrade the power supply so I can add in a new GPU. To my surprise the motherboard takes a tenpin power connector with one blank and I have never seen anything like this. I have search the Internet and I am not able to find a solution. Power supply that I purchase is a thermal take 600 W power supply with a 24 pin that has four pins that can be removed. Computer bought is a Lenovo Ideacentre 700. I am actually able to insert the 24 pin on the tenpin and it fits but I have not turned it on to the fact that it can fry the motherboard. Any suggestions?
