So i bought a new motherboard and i has a 8 pin power connector but my PSU has only 4 pins...i am using these 4 pin in my 8 pins ..but the computer is running slow.. can i use 4 pin to 8 pin converter ? or should i buy a new PSU ?

My CPU ( ryzen 3 2200g ) has integrated graphics but graphics are not working well ( very slow ) , it's because of this 4 pin connector ?

Please help
