Hi all,
I've just got my hands on a new Tagan Easycon TG580-U15 psu, I have a little problem connecting it up to my dfi ultra-d board.
these are the connections I'm not 100% sure about...

and this extra removable cable..

-Which 4pin 12v connection do i use? the "p4" or the "p4+" separate cable. I'm pretty sure the "E" connector makes up the 20 pin atx plug to a 24 pin power cable. and I assume the p8 connector is not used on my board.
-Also where do i fix the ground/rtn cable to? (chunky gauge black cable with a gold ring connector), the manuals non to clear.
Initially I though connecting it to the case chassis or not connecting it at all as the psu would be grounded anyway. but the manual has made me a little unsure.
thanks for any help with these
