Thanks Nils. Indeed my PSU has both a 4 and and 8. Its a modular PSU fyi. If I compare the pin on the 4 and the 8, both the wire colors and the shapes of the individual plug holes line up and match perfectly. My vendor thought I was plugging one of the Modular cables into the Mobo... took a while to convince him I'm dumb, but not stupid. Once he was convinced there was both an 8 and a 4 pin molex, he became unsure of which to use. I then spoke to the manufacturer and got the exact info you gave which is either works, but the Mobo takes advantage of individual power channels if available. (It took a 30 minute hold time on the tele to get this). I just tie wrapped the 4 pin out of the way, plugged in the 8 and it worked great!
