VRM on the motherboard still matters. Lots of people got confused with all Haswell stuff. On 1150, motherboard's VRM converts current at DC12V down to about 2V for FIVR. While VRM gets less stressed since it converts down not as much as before, it still does most of the conversion. What FIVR does is it converts the power even more to different CPU lanes like vcore, iGPU, IMC and so on.
Saying that, MSI doesn't use completely bad VRM for their z87 line up even on the very cheap ones (G41).
So VRM throttling is still possible, and fire hazard can happen even with very good VRMs if thermal throttling is not implemented correctly (Gigabyte X79 at first).Edited by DeXel - 11/18/13 at 1:40pm
