atxpwr2 question

[xaeniac]

Just received an I7-2600 that I think is faulty. Continue to get errors such as WHEA unrecoverable within windows boots/installs, etc. The only thing i noticed was the atxpwr2 cable has 8 pins on the motherboard, but on the powersupply only has 4. my i3-2100 works fine, but figured it was noteworthy and wondering if this would cause an issue between processors?
