Product: hp z220

Hi I am looking into purchasing a old hp z220 and need to upgrade the power supply. I am not sure how many pins the main motherboard connector has. Since I do not have the pc yet I have to look on YouTube and google. Some YouTube videos show 20 pins. then all the google images show 18. I'm not sure which is correct but maybe someone who owns the pc can tell me.

 

 

Thanks!

@Tophi,

CMT has 18 pins on the main, and a 4 pin auxiliary.  https://www.empowerlaptop.com/p/655842-001/

Although you did not ask, the SFF version is different  https://www.empowerlaptop.com/p/655840-001/

 

That PSU is not an ATX plug.
