Little confused here... in the manual it says I MUST connect the 8 pin ATX power blah blah blah, yet, it comes shipped with a blockoff plate letting you only plug in a 4 pin. I can remove the plate, but, will I damage anything by connecting the 8 pin or am I only supposed to use the 4 pin.

The cover is so that people won't be confused when they only have a 4-pin CPU cable. If you have an 8-pin CPU cable, then remove the cover and plug it in.

That makes sense... i do have the 8 pin and plugged it in and we're good to go.
Btw, nice name, Laing ;)

I also have the same question, but thanks to reading your reply I'm less confused. however, my power supply has both cables available - is there any benefit?

The 8-pin connector was introduced to feed the more power hungry multi-core CPU's, especially quads.
If you're PSU and motherboard has an 8-pin connector, just plug it in.
It mostly comes in two ways on the PSU. Some have both a separate 4 and 8-pin connector. Others have a 4+4-pin connector, so you accomodate both types with only one cable.

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!

Thank you.
