Reduce power consumption

Hi fine folks @tom's hardware,

As the title suggests I'm trying to reduce the power consumption of this build I did. Its a sandy bridge build I did not so long ago purely as a desktop/workstation but now I'm trying to turn it into a server that I could use as a workstation every now and then but also run 24/7.

The current spec is as follows,

Fractal Design R3 case
Intel i3-2130 3.4GHz
Asus P8Z68 Deluxe GEN3
G.SKILL Ripjaws X Series 16GB
Seasonic SS-460FL 460W power supply
Asus 8600GT (I know this is very old but I don't intend to run any games or GPU hungry tasks)
Intel 60GB SSD 330
2TB WD Green
Corsair H80 cooler with dual Cougar CFV12H fans in push pull config
2 CFV12H fans + 2 stock fractal design fans for cooling

With everything running at idle (that is at EFI Bios) it draws about 100W. Which is way too much. I have not loaded the OS yet. I then plugged in the Corsair H80 and all the fans to a separate power supply and unplugged all the hard disks to check how much the CPU+Mobo+Seasonic power supply+Mem draw and its still in the range of 85W.

Does anyone have any ideas about what I can do to reduce this power consumption ?

I appreciate your help

Hi :) 

You are kidding right...100w is the cost of a light bulb ...lol

All the best Brett :)

Remove the 8800 and use the integrated HD GPU will probably be the biggest reduction.
Turn on power saving options in the bios and load control software in windows so it can power down cores as needed.
