Alright, so I've almost got my new gaming rig all hooked up ... still waiting on the two SLI graphic cards to arrive. I am a little confused about the PSU connections though. I have the 8 PIN hooked up ... and then there is a 6 pin cable. Do I need it to aid with the two graphics cards? If so, there is no where to hook it up on the MB ... that being the case, should I get this adapter?

I've got the 20+4 atx main power cable, the 4 pin atx +12v cable, the 8 pin EPS +12v cable (or maybe it is the 8 pin PCI express cable??) all hooked up. Then there is a six pin cable ... there is no where to put it on the MB, and no it is not the 6+2 I keep hearing of. My INSTRUCTION manual did not include English instructions! http://www.newegg.com/Product/Product.aspx?Item=N82E16812200106

PSU is Raidmax ky-600atx 500w

Adding 2 of these graphics cards ... http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=5639261

http://www.playtool.com/pages/psuconnectors/connectors.htmlJason, that link is what I used to describe the ones hooked up.The 6/8 pin from the PSU are for the PCIE power connector of your Video cards. Since the PSU has one 6 and 8 pins only(?), use the Video card supplied power adapters as your 2nd option. http://www.evga.com/support/KnowledgeBase/Default.aspThe Gigabyte motherboard has an 8-pin molex connector.  That must be CONNECTED to the PSU for proper functioning.  The EVGA GeForce 9800GT has a power Y-adapter, with 2 4-pin molex; can't see if they are both pins or one is sockets & the other pins.  If you have extra cables on the PSU, just don't use them.
