I'm trying to connect the PSU to the mobo but do I have connect the 8 pin ATX V12 connector? Because i have an old PSU and it doesn't have one. I'm also trying to connect the front panel headers. http://gyazo.com/e0bcf4cf3cf14ad4b088f4c263d24d23 this is the picture of the plugs in my mobo. I have a Zalman z11 Plus so I have a pled 1/2, power sw which takes up 2 slots(should i just put that in the GND slot?), i have the reset sw and the HDLED. My PC is not powering on. Is there something with the 9 pin ATX V12 connector?
