    Dunno, it seems odd they wouldn't include it on desktop parts entirely. Especially if the issue was as non-existent to begin with as some have said. Not even any of the PSU manufacturers apparently knew it was going to be disabled outright.

    Personally speaking it doesn't impact me as my chip will run 24/7 under load making the power state useless. I regret the continued absence of VT-d more than S0ix honestly, it's irritating that if I want an unlocked chip with VT-d support I'd have to buy a more expensive proc that's two generations out of date.

    I was curious about this as I built a new rig for my brother this past week:

    Intel Core i5 4690K Haswell
    Gigabyte GA-Z97X-Gaming 3 BIOS: F4
    Kingston HyperX Beast 8GB 2400MHz 1.65v
    Samsung HD103SJ 1TB
    Crucial M500 240GB
    3x80mm Pabst case fans
    Seasonic S12 430w Rev: A1 (SS-430HB Active PFC F3)
    C6/C7:	Disabled	Auto	Enabled
    AC Draw	77w		77w	72w
    CPU	7.2w		7.2w	5.1w
    Ammeter	1.84AH		1.84AH	1.63AH
    The ammeter was on the 8-pin CPU power cable.
    Yea, those 2.1w in difference sure are going to blow up allot of PSU's!
