Sergey, I took down the server at the weekend to install a newly built kernel and insert the power monitor. 47W - All services running at idle, tuner power saving disabled 44W - All services running at idle, tuner power saving enabled As tuners are powered down most of the time, that's a handy 6% average saving. The hardware is an HP 8300CMT with high efficiency PSU, G2130 Ivy bridge CPU and a 3 x 2T RAID + KMC4400R for CCTV video capture, the tuners are PCTV Nanostick 290e for HD/SD (USB2) and an old Leadtek DTV1000 T (PCI) for SD - both of which are super-reliable BTW. Obviously other tuners will vary, and if the PSU isn't the efficient 90% one like this, the savings will be marginally more.
