PC with least Electricity consumption possible for running 24 hrs continuously

post #1 of 13
Thread Starter 
i want to build a pc with the following intentions

1.24 hours running
2.Least Electricity Consumption Possible (important)
3.no noise + should run cool
4.used for only doing things like

Downloading
Recording from cctv feed
youtube playback


5.include a good wifi card to transfer files from my other pc wirelessly
6.Budget = as cheap as it can be
7.Long lasting components
8.no speakers
9.intel or amd which ever fits my needs (sorry for posting in intel section as i could not find section having both)

anything else you should know??

suggest please

Probably an AMD E-350 or C-60 APU as the core of the computer with an SSD+hard drive configuration since you will probably store what you'll download. Those APUs can also be cooled passively so it will be perfectly quiet if you don't use an HDD (ex: download directly to a file server). Also, I'm sure there are E-350 boards with integrated wireless. All you need after that is an ITX case with a power supply.

This one has built-in wireless but costs more. It also uses an Intel Atom, but thats fine for what you want to use it for. http://www.newegg.com/Product/Product.aspx?Item=N82E16813500074

How much hard drive capacity do you need? Anything that you already have, like a case, memory, etc?

EDIT:

Here you go:
http://secure.newegg.com/WishList/PublicWishDetail.aspx?WishListNumber=30263868

Just pick a case and SSD (or HDD). This will be dead silent (totally passive), VERY power efficient (80Plus Platinum PSU), and decently fast. Noticeably faster than the suggestions made above (it's got a 35W Sandy Bridge CPU). I believe this also fits your requirement of "long lasting components" better.

An additional way to cut costs would be to use Linux, which should be feasible for the uses you have described.

i have Fedora , Ubuntu ,
but which version should i use
amd 64 or i386 ??

HDD = 1tb should be enough i think ............ i regularly take backup to my portable hdd to store whatever i download (if i need to store them)

is there any way to use less than 400w ? i mean can u bring down the power usage to less than 400w?

the cpu cooler = No fan right ?? will it cool well ? (i have not used any fan less model yet)

i have A question ............ does having more pcie ports increase power requirement ?
i mean if i take a mini atx or atx board in stead of a mini itx ?

yes those look good
checking the amd processors now
never used a amd processor before.

Power = how much should i take
What is the minimum possible ?

To all:
I had a look at FoxConn Nano Pc
how are they ?

The CPU in that wish list is 64-bit, so you would want the amd64 version. The system will not use 400W. That is just the maximum amount of power that the PSU is able to supply. Since it is an 80Plus Platinum certified PSU, the power draw will be minimal (operates with ~90% AC-DC conversion efficiency). With the CPU cooler I listed, you would not need a fan, it is designed for passive operation, and the CPU has a very low TDP.

Using this PSU calculator, assuming a 100% load on the CPU and PSU with the listed components and 10% capacitor aging, with a single green SATA HDD and a single regular 120MM fan, the power requiremtns are just 123W, and since the system will never operate anywhere near 100% load for most of the time, the requirements would really be much less, and the power draw from the wall would be only a little above the actual requirements because the PSU is so efficient. At 50% CPU and 60% total system, power requiremnts are just 62W, and really, the load would probably be even less than that (probably like 10-20%).

If you don't use any fans at all and have an SSD instead of an HDD, the power draw would be less yet.

I have serious doubts about the reliability and longevity of those all-in-one type mini ITX boards, especially for 24/7 usage. Also, the smaller and more cramped things get, the harder it is to be passively cooled.

That PSU is actually the same one I have in the system listed in my signature. It is fantastic.

The E-350 draws 14 watts at idle, 23 watts at full load. Yes, 23. Most of those type CPU/MB setups only come on mini-itx boards with one PCIE slot. What would you even use a PCIE slot for in the build that you are planning? You will not need dedicated graphics. You could put a Wireless card in it I suppose, but a USB adapter would work fine.

oh one thing i forgot
i will ttransfer files to and fro many times a day

as you said the system wont use 400 w , but it will draw from the grid a power of 400w , right ?
i am not a electrical engineering student !!

so it will only draw power whats necessary .........
so less electricity bills

and less fans = less consumption as well

so ......... as i am conscious about my electricity bills , so i am asking ......... i have to pay for only about 62 W of power usage and not more than that?

as for your other points
i agree about
more the cramped system = more heat = less life
so is there any non mini ITX boards (just to be on the safe side) .......... as you pointed out that you have doubts about them running 24X7
for example any mini atx board
i have a spare cabinet (atx) left in my room with one fan only ........... i can use it

you are suggesting to get a usb wifi ??

I recommend the following power supply, provided you get a TFX compatible case:
