I bought a new evga PSU to replace my factory 300 watt PSU, while installing my new PSU I noticed a 4 pin connector above my 24 pin connector and my old PSU didn't plug into it but I'm wondering if my new PSU requires this connector? I think my new PSU has a cord that connects to it,but is it required? Here is a link to a picture of my mobo, it's the white connector above the 24 pin
