So I am building my first computer. The only problem is with the PSU and all the connectors. I have a OCZ 600w and a z77 pro extreme 4. First I dont know what the red 8 holed slots on the psu are. second Can I plug multiple devices into one cord. Example: can I use one cord ATA power cord (had several slots) in my blue ray and another in my hard drive. Please help.
