Does CPU 8 pin need to be plugged in to boot?

post #1 of 9
Thread Starter 
Hi everyone, I'm in a predicament described by this post.

Bottom line is my 8 pin won't reach the motherboard with my new case, I'm waiting on an extender and wondering if it's possible to use my rig (Sabertooth Z77 + 3570k) without having that plugged in. If yes, than can an overclock be done too? I'd appreciate any advice.

8-pin is your supplemental CPU power. no plug means no boot.

You need the 8pin cpu power cable in. Try going through the motherboard side of the case, to see if it reaches for now.

Darn, there's no way it's going to fit any way, just have to hope the extender gets here soon enough. :/

Just curious, do you have the fan facing down so the non modular cables are closest to the motherboard tray?
