Which Power Connector?

Ask the Doctor LogoI have what I thought was a simple question, but I can’t seem to find a definitive answer. I have an Asus P6T Deluxe motherboard and a Core i7-930 CPU. Should I use my PSU’s 8-pin or 4-pin connector for the CPU?

Power-Not-Good Signal

Ask the Doctor LogoI have been having an issue with the rig I built back in June. Occasionally, usually when I first boot in the morning, nothing happens when I press the power button. I have found that cycling the power strip and power supply, disconnecting and reconnecting the cord, or slapping the side of the case fixes the problem. I have also had some rare instances where the computer unexpectedly shuts down, as if it were unplugged. Since this is a relatively new rig, most of the parts (with the exception of the motherboard, which I purchased as an open-box item) are still under warranty. I just need to know what component might be at fault—I suspect the power supply or the motherboard.
