How can I reduce my idle power consumption further

post #1 of 4
Thread Starter 
My rig specs are in my sig but just for reference we are looking at:

Specs: Warning: Spoiler! (Click to show)
  • Lian Li PC-A04 with 3 120mm stock fans plugged into Molex leads
  • Antec Neo Eco 620W power supply (2 years old)
  • 4 DIMMs G.Skill Eco 1600MHz (4x2GB)
  • Intel Core i7-875K overclocked to 3.866GHz multi 29x133MHz on stock volts. CPU-Z reads 1.28 V idle
  • Razer Lycosa backlit keyboard and Razer Deathadder plugged in via USB
  • 1 DVI-D monitor, 27" 2560x1440 LED
  • EVGA Nvidia GTX 670 stock speeds
  • 2x WD Green Hard drives 2TB
  • 1x Seagate 4TB 5900RPM
  • 1x Samsung Spinpoint F1 7200rpm 1TB
  • 1x Samsung 470 series 128GB SSD
  • 1x Samsung Blu-ray drive
  • 1x 120mm fan plugged into motherboard header for CPU cooler
  • Gigabyte H57 microatx board LGA 1156

My PC is plugged into a surge protector and directing into Killawatt meter at the outlet. Logged into Windows 7 with a few browsers, and Skype open I monitored

175 Watts Idle

I think I draw somewhere close to 300W in a game, I'll have to re-evaluate it.

Anyways, please help me reduce my power consumption at idle. I am considering upgrading to Haswell Core i5-4670K but I heard it will only reduce power consumption by 10W. I thought my PC would idle at only around 100 Watts so this comes as a surprise. I thought I enabled all the CPU power savings features in BIOS but CPU-Z sees it at 3.866GHz 24/7 and idle on my GPU is 324MHz.

Your power consumption will drop dramatically with Haswell - just as an idea my Ivy Bridge 3570k @ 4.0 (stock voltage) + 660TI o/c'd pulls 40W at movie playback according to my APC battery backup. You might pull a few more watts because of HDD's but i'd say not much over 50W total power consumption.

(note that doesn't include my monitor as my 30" dell pulls likely as much or more than my computer biggrin.gif )

I figured it out. I went back into BIOS and checked the CPU Features. I remember being told to not enable Turbo Boost when overclocking and now I see why. CPU-Z was reporting correctly, it was always turbo-boosting because it was sitting at 3.866GHz even those my multiplier and base clock only set it to 3.6. All the other power savings features were set to AUTO which is the default but I went in and manually selected ENABLE and now I am only drawing 102 Watts at idle. In case anyone's interested.... but I bet if I upgrade to Haswell, it would be even less.
