Hi,
I wanted to build a new computer with the super low power atom. ( my 24/7 video server draws 300 watts idling and I want to build a low power system) The atom i want comes on a mini itx board. I also wanted to have 2 full size sata hds and a 80+psu. Will a micro-itx mother board fit in a full size atx case or a micro atx case? I know the board will physically fit, but will the screw mounts line up? Also for the power, can i use any power supply that has a 20 pin main connector? I am looking at a full size psu that is a 300 watt an d 80+. It is 20+4 for the main connector, just wanted to check if it would work.

Thanks,
Cody

You have other choices for motherboards that run the Atom CPU. Look around, below is one example that is mATX.

that board uses more power...i cant find the site now,, but the board i want only draws 21 watts.

Yes, but you will be drawing additional wattage with extra drives too.

Looked at newegg.com for mini ITX PSUs. They use 20+4 power connector.

If you use an ATX or mATX PSU you will be using power at idle with the PSU in addition to the draw from the board and drives. I think overall you will not save near as much as you think.
edit
I would guess you would need to mod the case. The back plate would be the problem. Drilling and tapping holes for standoffs shouldn't be too hard.

obviously i will use more power with drives, but I am trying to go as low as possible. I was going to use a full size 20+4 psu that is 80+. (no itx ar 80+ aside from silverlite which can only be bought with a case that i don't want.) Most psu are most efficient at half load so i think that would be better then getting a 150 or 200w.

I know you weren't going to use the mini ITX PSU. I just pointed out they use standard power connectors.

I don't know if they are or not. I suspect they won't align or the ports out the back won't line up.

Are you adding in any cards? That up/down alignment could be a problem too.

well i have confirmed the power set up will work...my main question is what will be required to physicaly fit a itx board in an atx case? Is it possible, will the back plates line up?

One major advantages of the Mini-ITX form factor is its backward-compatibility with
the ATX specification. The Mini-ITX motherboard can be installed in any ATX chassis.
Figure 4 shows the required maximum component height constraints for the
components on the PC board. For full compliance with Mini-ITX, and to prevent
interference with the chassis structure, power supply, or peripherals, the motherboard
components should not exceed the height limit in each zone defined. Similarly,
compliant power supplies, peripherals, and chassis features should not extend into the
motherboard component area.

I think you misunderstood my question. I'm curious what you want to do with a low power, low performance system...emphasis on "low performance".

i want to keep it running 24/7 for downloading and a NAS. I want to run torrents on it, but if i want to do any real video work I will use my desktops that used more power. My current desktop idles at 280 watts which is about $20/month. Iw ant a system that cost about 5 or less per month.

Have you used a watt meter to determine the idle usage? If so, what do you attribute the current draw to?

Your goal when using the hardware you mention above seems unattainable. The processor itself doesn't account for that much wattage. Even at your numbers it will take you at least a couple of years to recover your initial costs before starting to see any true savings.

I have used a "kill-a-watt" watt meter to measure the ac draw of my system. The main draw on my current system is the graphics cards. It also has a q6600 which seems to use tons to idle. The board I want has built in gpu and cpu. It uses only 21 watts (dc). My current had use about 10 watts with low to moderate work. I will be buying 2 "green" hard drives which should draw even less. (mirrored raid) I wont be using any dvd-drive aside from install. Ram will use a little, but this whole system should run at less then 50 watts. I know I am mixing ac and dc and I should account for a loss of all DC wattage. My psu is 80+ so I shouldn't loose to much. According to spec the green drives only draw 8 watts at peek and down to 1 watt when doing small amounts of reading. The only other option I was considering is a laptop with external storage. Most laptops run at a supper low 25-35 AC watts. (why don't they make desktops with laptop parts?) Of course my external storage would require separate power form a low efficiency adapter. Also raiding external storage is expensive.

OK, you have thought this through. Still, by your own numbers you may save $15 a month. How much are you spending to build this.

You are hosting torrrents for download then? Risky business isn't it?

dloading an up lol....torrents are not necessarily illegal, depends on what they are...the debate of illegal downloading aside lol...they system payback would be about a year not including the green hd's. I was going to buy them for my main system for storage anyway. The mobo, psu, case and ram are about 150. That would be a 10 month payback. I not only care about saving money though, I care about being green. I drive a car that runs on bio diesel, I work for a solar installation company..the least i could do is build a more energy efficient computer. I guess the question now is, does any one know of any mobo cpu combos that use less then 21 watts? The hd's and psu are gonna be the same with whatever mobo i use

How about getting a real board & a real CPU, then underclocking / undervolting? The single core AMD Sempron 140 Sargas (2.7GHz) is a 45W CPU & there are plenty of energy efficient AMD IGP chipsets (740G, 760G, 780V, 780G, 785G). Pick your combo, tweak the BIOS settings, enable Cool 'n' Quiet & you'll have a much better performing system with similar power requirements.

Here's an early review of the 740G from Aug '08:

"The greatest strength of this platform is likely the power consumption. At idle, with 2GB of memory, a 500 GB HD, a BD drive, and a X2 4050e, the system is pulling a very meager 55 watts from the wall. At full load it is pulling 91 watts. If we consider that the Atom and Nano platforms that Ryan tested last week were around the same idle power, it is impressive to think that a comparatively fast dual core processor with a fairly robust integrated graphics portion is sitting in the same area at idle, and at full bore it is about 20 watts higher than the Nano with its VIA/S3 Chrome based chipset and about 30 watts higher than the Atom and the 945 chipset. When we consider availability and cost, the combination of a 740G with a 4050e processor is one which will appeal to many users who are looking for low heat, low power, but robust features and connectivity. Also consider that the platform is fully Vista Aero and 64 bit compliant. Neither the Nano or the Atom platform were able to run Vista 64 for Ryan. The AMD combination runs pefectly fine, even with full Aero enabled in Vista."

I've re runt he numbers using laptops hd's and i'm down to about 15 watts idle, 30 under load. I don't think I can get much better then that since energy efficiency is my primary concern int his build.

Look at the via artigo. I think I saw it listed at 9 watts under load. Might have been with a ssd or cf drive though.
