I just finished my first build in 12 years. I have the ASUS P5B delux MB. I have a connection at the tope of the MB (as is looks installed) that had 4-pins and a cap over the other 4-pins. I pulled the cap and plugged and 8 pin connector I have twith my Allien PSU. The MB directions were a little confusing on that part. Im not having any troubles on power up, even tho I cant get the system to work. But what is that connection for? And was I correct to remove the 4 pin cover and install my "8" pin power connector to it> :?
