I have an MSI N750TI-2GD5/OC and I'm seeing about 9 watts of power draw at idle and around 75 watts at load as measured by my killawatt meter. I stumbled on Freekers post (quote above) where he saw 5 watts idle with his gigabyte card and I was wonder how you achieved this? Was this possible because of the custom BIOS you flashed to the card?
I'm really only interested in this because I'm trying to investigate how to tweak the BIOS so to get the power consumption as low as possible while still having a functional system.
Every time I have used a custom bios, it has removed the idle pstate for the cards to drop to idle clocks and voltage. You can get better voltage/ clock speed ratio with a custom bios, which can allow you to achieve better efficiency under load, but any other time you will sending quite a bit more power to the card on idle.
The lower speed the fan is and only having 1 as opposed to 2, would automatically qualify it to draw less power.
Edit: And honestly, if you were to get a 750 Ti then you should look into the power target % and overclocking the core and memory speeds. This has dropped my power consumption on all of my Nvidia Kepler based cards.
