    I might be able to test one out tomorrow. We have a ChromeBook that isn't used so I'll check it out in the morning.

    Hi Guys,

    Thanks a lot for your replies. I am just about to order Intel Celeron N2820 .

    Just I want to know about below stuff:-

    1. Which RAM should I use in order to stick to Low Watt system? Will 8GB beneficial or useful on such system?

    Specs Given:-

    SYSTEM MEMORY
    • One DDR3L SO-DIMM slot for memory expandability
    up to 8 GB
    • 1.35V, 1333/1600 MHz (down clocked to 1066 MHz)

    2. Hard disks

    Is there any SSD which comes with 3 Gb/s speed ? What if I connect Gb/s speed SSD ?

    Specs Given:-

    1x SATA port (3 Gb/s) for internal support
    for 2.5¨ HDD or SSD

    Edited:-

    What if i connect this SSD 6 Gb/s

    It also saying "
    • Ultra Low Power Consumption for Longer Battery Life" in it's description.

    http://www.snapdeal.com/product/samsung-840-series-120-gb/1412846#bcrumbSearch:|bcrumbLabelId:283


    Please advise.

    Why not a Intel Celeron J1800?

    1. 4GB ram is enough
    2. No issue when u connect a SATA 3Gb/s device to a SATA 6Gb/s or the other way around.

    No way man... I did read all about these. but decide against it as it would require SMPS....:banghead::banghead::banghead:

    So basically you are buying a NUC with Intel Celeron N2820.
    great.:toast:

    Certainly yes.

    There are various types of system we can choose from which I learnt about from these thread:-

    1. Intel Celeron NUC N2820 (Good PC and can handle day to tasks with 1080P 13watts max.)
    2. AMD AM1 with with AC adaptor compatible motherboard (Lowest AMD PC max 25 Watts)
    3. Intel Celeron J1800 the one you specified but it would require Mini ITX box with box size SMPS.
    4. Intel NUC i5 model, I guess, this is "too must" have for all as this is more powerful and less size, bit expensive with all req. parts though.

    My idea is to have Intel NUC N2820 and hook it up behind 23" LED monitor (max 18 Watts) so combine desktop using experience won't cause me more than 30 Watts in total more over I can use it as All in one PC too.

    In short my total power consumption should not exceed 25 - 30 Watts.

    I just set up a laptop with an N2830(faster than the N2820), and it was super slow.

    Just chiming in a 2nd, 3rd and more time for the 5350 AM1 even though it looks like you made a choice :) Just built a similar power sipper and I am very pleased for a basic surfing / streaming business machine. And surprisingly it is quite snappy - quick for a budget non gamer.
    http://www.techpowerup.com/forums/t...ni-itx-desktop-build-business-machine.204060/

    On another note, if you run the maths the difference between 25w and 15w used 10 hours a day at an average of .11 cents per kwh is only $4.01 a year :D

    $10 total electric cost rounded per year for the amd
    $6 total electric cost rounded per year for the Intel

    Your current setup if using 88w used for 10 hours a day at .11 pkwh is only costing $35 rounded a year so really not all that much. Or at 109w 10 hours a day equals just $44 rounded a year.

    Do you have crazy high electrical costs in India?

    Good review / Comparison AM1 vs Intel competition. AM1 is considerably better for a lot of things such as multimedia, offers 6gbps sata and more. Smarter low power choice IMO

    Comparison.. 5350 even being low end wipes the floor with a N2820

    But its much more powerful lol

    He has made his choice it sounds which should suffice for what he's wanting to do.

    I may be saying something redundant because I only read the first page and the last page of this thread. You say the intel g2020 uses 55w but that is tdp now power usage. By g1620 uses 14w according to hwinfo, which I can confirm is pretty darn close using my kill-a-watt wall meter. I have even undervolted it enough where it will use 8w according to hwinfo.

    Just running some general measurements on the AM1H-ITX mobo and 5350...
    - Idle is 19-20w
    - General usage 22-25w (browsing and so forth)
    - Streaming Netflix 28 - 32w

    No undervolting. I could undervolt the ram but no options for the cpu with this mobo. So with my combo - it is what it is.

    I just tested my i5 laptop

    Intel i5 3210m (35W TDP), 8GB 1600MHz ram, 60GB intel 520 SSD, not sure if its running the intel IGP or AMD GPU at idle, tbh.

    11W idle (screen off)
    13W idle (screen on)

    1080p, H264 10bit video file, streamed over wifi N 150, software decoded via CCCP and LAV filters - 21W.

    so you know, the TDP numbers dont tell the whole story.

    Good info and low power! Had me curious as to my I5 laptop as well. A dell E6420. It has a lil 2540M cpu. Just tested with the battery at 100% / wifi ON / Screen at 100% / 180gb corsair gt SSD / 8gb 1600 / current drivers / Keyboard on dim / in performance mode as I keep it all the time
    - Idle is 16-17w
    - General usage 25-27w (browsing and so forth)
    - Streaming Netflix 28 - 30w
    - When charging 45-46w (just verified it on my wifes dead 6420)

    Overall much better than I suspected. And the 2540 wipes the floor with the 5350 as anyone would figure

    My current system running ~10 hrs daily costs $13-15 a month.
    So the electrical costs is a little high. ~8cents per kwh.

    Thats low - we pay about 25-30c per KWH here.

    I pay less than a penny per KWH with all this cheap hydro power around me.

    im on a fixed budget for my electric. its about $200 a month, however its split by my other room mates. This includes the cost of running 3 window unit A/C systems, 2 are 5000btu and one is 12000. and in winter we use a lot of electric space heaters 3-4 of them each about 750-1500w (i like the quartz ones), though i only use them in the rooms i happen to be in at the time, sometimes I open the oven (gas). no central heating and air. we have switched over to the newer CFL lights which has helped a lot. I plan to again switch to LED lighting when it gets more affordable.

    as far as the OP build... an intel NUC unit sounds reasonable, perhaps even an all-in-one based on an intel NUC with a celeron 1900 (the quad core one)

    that he's using the hardware he mentioned and its slow.

    power efficient doesnt mean fast.

    in fact power efficient is generally slower... though tech has come far enough that low power devices can be quite powerful performance wise... well more so than they used to.
