If you notice your 12V lane is very low under high loads, it might be best to connect them.

Most motherboard manufacturers have/had something like this... Sometimes it's a molex, sometimes it's a floppy power connector. DFI and MSI are only ones I know of that have this on their X58's though
Would I need to connect these if I'm going to run two GTX 275s in SLI?
