How to save electricity on computer using Windows 8.1

[pigulici]

Well, you must know that there is not magic software for desktop where you click and you consume less electricity, also the peak of consume it is when you play games or encode video(can't do much here); my advise: go to uefi motherboard, load optimized default, and be sure you have:
- EPU power saving mode - enable(pag 88 from manual)
- Xtreme tweaking - disabled(pag 90)
-Enhanced Intel Speed Step Technolgy -enabled (pag 97/108)
- Turbo Mode -enabled(pag 97/108)
- Intel Adaptive thermal monitor - enabled (pag 107)
-Cpu C states -all enabled(pag 109)
-hdd on sata ahci (pag 112)
-agressive lpm support - enabled (pag 112)
-pci-e native power management - enabled(pag 116)
-dmi link aspm control - enabled(pag 116/117)
-aspm support -auto(pag 116)
-peg aspm control- auto(pag 117)
-aspm support - enabled (pafg118)
-Erp ready -enabled(pag 119)
-cpu q fan control - auto(pag 122)
-chassis fan qfan control-dc/pww mode enabled(pag 123)
Disable in uefi what you not use (like sata chipset from asmedia, pag 118)
On windows power management put the profile balanced(and here you can set more agreesive the time to go to sleep/standby, at me the monitor go to sleep after 20 min, and all the pc after 45minutes of idle).
Make sure you have latest drivers , bios and updates to all software you use(at my hd4850 I put another bios so the clock in idle it is now 150mhz from 300mhz, or you can use the tool from vga card to underclock the vga card in windows).
Make sure yo give a real shutdown to windows 8, if you google will see that win8 enter in some kind of sleep , not shutdown.
The undervolting of cpu it is most used on laptops, so I don't know if make much difference on desktop.
That it is the free way, the not so much free it is to buy a PSU with more than 90% efficiency and a big ssd.
p.s.: also , let the minimal software in background(I close adobe autoupdate, chrome auto update, etc..)
My 2c....

15 dollars is what I save from turning off my machine at night. I doubt it's using that much power just because it's plugged in, if it is, it's not turned off.

Comme on I am not that kind of guy, I know how to turn off a PC, my country is Romania if it helps with my statement.

Hello! thank you all comment.

I'm using Windows 8.1 Pro 64bit. CPU Intel i5-2500k, Mootherboard Asus Maximus VII Pro, GPU Asus GeForce GTX760, PSU Cooler 1000W, Ram Corsair 8GB.

Jobs: Corel Draw X6, Adobe Affe..CS6 and more.

Gaming: Battlefield 4, DCS Black Shark 2...

SoundMax 5.1. and more...

Isn't a I5 2500k skt 1155 and maximus VII skt 1150 though?

Maybe it's just a typo, and he has a maximus-something socket 1155

I tried using the power saving mode on win 8.1, but I dont know why, when using that mode my FPS on Aion drops from constant 63 to 35-40, then if I change it back to Normal or Performance my FPS goes back to 63(on ultra settings). I checked CPU and GPU speed/voltages while on power saving and everything was the same compared to Normal and Performance

or maybe if he just seldom gaming he could use low end vga card

Silas ,yes the prices are silly high compared with average income ( about 350 to 500 USD)
If u can do it get a small high efficiency PSU, it really helps.Mine gives 430 w ( can do more ) and at idle uses 70 wats (with monitor) and on load 280w

Nah no upgrades for this pos PC, going to spend about 1500-200$ when skylake and big maxwell launch, more on that when the time comes.
