P55-UD6 socket burn

[Raja@ASUS]

i dont know about an 870...
where do you get the 15-20% switching loss though?
the pwm engineers at foxconn told me the load efficiency of the p6t, gigabyte x58 extreme and BR are all around 90%

im sure the "24phase" thing from gigabyte has a worse efficiency though...
but this is a 1366 cpu, so i guess you meassured it on the evga 1366 digital pwm? if the efficiency is around 90% you get 25W more for vcc, around 185W...

even if the efficiency is really only 80-85%, i wouldnt be surprised if the low temperature is making quite a diference here, and current draw at higher temps is notably diferent.

Most PWM circuits have an efificieny of 85% at the very best. The 4.45Ghz measurement was not on a cascade but water cooled at ambient temps. THe 870's CPU's do not pull more than 1366 CPU's to VCC - I have checked. What have you measured? Nothing I suspect
