My new build is based on an Intel DP55KG mobo that requires 3 power connections (a 24 pin, 8 pin, and sata as a gpu power auxiliary). I have a corsair 650W PSU that doesn't have any 8 pin connections, but it does have 2 4-pins tethered together. Will using these two 4 pin connections do the job, or are the 8 pin psu connections somehow different (am I risking frying my mobo)?
