iCUE is pretty decent for showing some info
Would it be the 12v power I monitor?
A core frequency of around 2160 is basically where a card will tap out with a 400w max power draw. So that lines up with the wall I have. I can't seem to get over 400w, therefore, trying to run above 2160 is basically a no-go with any serious load.
There is no way your card is doing THIS without the full 450w:
It's likely just under reporting. Watch the "12V power" in the Corsair readout at idle vs. maxed out in Furmark, and subtract the change in CPU power use. I bet its a 400w+ difference.
Ok, so this is idle on GPU. Occasionally drops to like 76w, or bumps slightly to low 80s, but I'd say 80w is fair for idle.
First curve in Kombustor that has GPU-Z/HWINFO reading about 390w.
iCUE is 510w.
510 - 80 = 430w.
Second curve, has a slightly higher frequency target/voltage, pegs GPU-Z and HWINFO to 400w.
iCUE hits 522w, though it wasn't perfectly held, dropping to 510~516w.
522 - 80 = 442w.
Soooo, underreporting??? Of course we're now relying on doing manual numbers based on what the power supply tells the iCUE software.
If I am above 400w, I guess my question would be anyone achieving like 2200mhz+ or running 1.1v, are they using BIOS even higher than 450w??? Shunt mods???
edit - Wait, is the CPU off the 12v as well? That would contribute something under a Kombustor load, even if it isn't hit too heavy with it. So until I know if the CPU is contributing wattage to that 12v power when off idle I don't think we're out of the woods yet declaring this simply as GPU underreporting.
