I have bought an asus x79 deluxe and am trying to connect a corsair rm 750 psu to it. The 24 pin connection is simple, but the 8 pin 8 atx connection is causing me grief and slowly killing me. Asus tell me it's an 8-pin ATX 12V Power connector. The Corsair rm 750 psu has a 6+2 PCIE socket and a 4+4 CPU socket. Basically if someone could tell me what cable should go in which one of these 2 sockets i'd be very grateful. A bit of background to this nightmare is that I'm getting the old classic turn on for 3 seconds, turn off for 3 seconds, repeat. I've read about too much thermal paste, taking out the BIOS battery for 30 mins, making sure the RAM is installed correctly. The motherboard manual tells me that if this 8-pin ATX 12V Power connector is not plugged into the PSU it will not boot up. No cable supplied with the RM 750 works. In my mind I'm looking for an 8 pin ATX male to male cable but after hours of only finding 8 pin male to 8 pin female/4 pin female I've given up.

The 4+4 connector is the one that you need. Should be female on the cable from the PSU connecting to a male header on the mobo.

Look closely at the plug and the socket. The plug will have some connectors that have all 4 corners fully squared off and some have rounded corners. Match the square/rounded corners to the header on the mobo and you should have no trouble making the connection.

Hi thanks for the help, but I'm still struggling. The cable that I have has one connection labelled type 3 (8 pin) that is connected to 2 PCI-E connections. The thing is that the type three connector fits into the motherboard and also fits into the PSU. The PCI-E connectors do not fit into either the motherboard or the PSU. It's like I need a cable that has the Type 3 connector on both ends of it. Does that sound right?

BTW. check out the DIMM slots on your x79deluxe. They are notorious for failure around the world. Go to bios and advanced settings/tools to check if the DIMM slots are working and see your Ram at all
