5.6MHASH@38W. Low clockspeed/memory speed
Is this a particular 750ti that has such low wattage? Is there some way to find these specific models? Some people in here were reporting like 68w.
Also 750tis have ridiculous overhead as far as systems go, but given that efficiency is almost double the 970s, that's a eyebrow raiser.
I've said this before and say I say it again; software reported power consumption numbers cannot be trusted.
The smi reported 38, 45, 46 watt cap figures are not representative of how much the cards can pull regardless of having a 6-pin or not.
If Sp_'s SMI figures were correct the 750 Ti would be 48% more efficient than a 970. That is laughable. That would be 6.78 W per mhs for the 750 Ti and 10.06 W per mhs for the 970 (to be fair the 157 W is a low fluctuation and the 970 is using slightly more on average so it has lower efficiency or higher W/mhs).
750 Ti's without 6-pin, with stock speeds and unmodified BIOS with release 55 are using 57.5 watt per card which is a measured figure while SMI is showing 38W. The real and measured efficiency of the 750 Ti is therefore 10.26 watts per mhs which is more in line with the 970 as expected.
Use a kill-a-watt or a multimeter or a UPS that reports power consumption but do not take software reported figures for granted.
That's what I thought. I use a wall meter to measure my wattage usage. It'd be weird if the same architecture and pretty much the same cards were THAT much more efficient. Lower clock speeds and memory speeds usually will save some power in addition to smaller chips which take less power, but not that much less.
Talk about hot!!!
These are my (2) rigs in the garage.
It runs about 95 degrees fahrenheit in there but I have a big fan blowing on the rig. ** The winter is great and cold in the garage so the rig runs very well! **
The entire rig is plugged into a power strip which is plugged into a kil-o-watt meter.\
Oh and I use every available space possible for mining. This is my office machine with (4) 750 ti's - kinda rigged :-)
Just figured I would share my set up.

Ahhh a tidy rig... Looks pretty. Closet shelving is pretty good to hang GPUs from. Little bit heavy though.
