Well, now that my confidence has been shaken I want to see what advice the experts have to offer. My Rampage III Extreme motherboard was confirmed fried this morning so I have replaced it with a Gigabyte X58A-UD3R motherboard and purchased a 1000W power supply to replace the Cool Master 600W PSU. I am getting ready to install the motherboard in the Antec 9-Hundred Two tower case and want to verify a couple of things - 1. I can mount the motherboard directly onto the little brass posts in the case that support the motherboard without any plastic or silicon insulators. 2. I only need to plug in the 24-pin ATX 12-V power supply plug to the motherboard. The other 8-pin power supply pin near the CPU does not get a power plug-in. Seems stupid to ask I know but, I want to be sure this time. Thanks for your time.
