I measured the power usage of my two titan blacks mining x11 with ccminer 1.2, roughly 600w for 11 mhash/s. This includes my CPU (i7 3770k) and a Samsung 840 Pro SSD running as well.
Kinda funny story behind them, they were given to me as a gift :smile:. Yeah, they are expensive but are worth it if you want to game in high resolutions. The fact that they seem to be very good for mining dark coin is great, used to all my hardware being inferior to AMD for sha256/scrypt.

Getting some weird fluctuations in my hash rate on v1.2 with two Titan Black cards. I often come home to find one or both cards running only at 1000 khash/s and have to reboot my system in order to achieve full hashing rates again.
Going to file a bug report most likely.
New to the forums and darkcoin, just thought I would post what khash/s I am getting with my nVidia setup with v1.2

Seems to be an issue with the latest drivers...
