In general, the new TDP of processor Haswell is on the same level as predecessor - not more than 95 watts. In another case. For new processor company introduces two new Idle - C6 and C7, which should lead to an increase in energy efficiency of Intel platforms. For example, the computer screen would remain active even in case if Haswell processor is in a deep state of inactivity.
The minimum 12 V bus power for processors must be at the level of 0.05 A. For Intel Ivy Bridge processors that threshold is 0.5 A. This may mean that older or simply do not meet the requirements of C6/C7 power supplies instead of the sleep system will be completely shut down.
The lowest possible currents 12 in the bus - specified by the manufacturer supply is not so common. Offhand issue can smooth out the motherboard manufacturers by providing a BIOS option to disable the transition to C6/C7. Related Products :
