Is there a mobo+cpu that comes close to atom's power consumption , and that can be used on the desktop ?
These are my options :-

1. Use Intel atom
2. Get some laptop cpu to work with a power efficient micro-Atx mobo. can someone think of such a combo ?
3. Find some low wattage desktop cpu+mobo. I don't think there is any.

I have my reasons for avoiding atom and Via's nano. Would love to hear suggestions for cpu+mobo combo that is ultra low in power consumption.

Thanks

Thanks for this. How much power will this combo use at Load ?
Also cost isn't the issue for me right now. Low power is. Its not for my normal rig but for a project (sortof) I have to work on.

You won't find another x86 CPU with as low a power consumption as an Atom and better performance, but there are plenty which can give better performance per watt with higher total power consumption. Tom's has had a number of 'Atom vs X' articles for various CPUs comparing performance per watt.

You probably want to look for the lowest idle power and then consider underclocking until the maximum load power is less than your limit. Even the i5s may be good enough if you underclock them, their idle power looks pretty good.

Motherboard runs about 35W

how did you manage to figure out the motherboards power consumption please?


From the article Badtrip posted -
Power required to finish the SYSmark 2007 Preview was smaller as well, hence this board won the battle for performance per watt. The only stain was the slightly higher peak power of 61 W as opposed to 60 W with the Gigabyte board.T

is this referring to the total power consumption (including ram,hdd) or just the power consumption of the mobo+cpu ?

Its sleep time now. thanks for all the suggestions. I'll do my research tommorow...

OK I am confused. According to this article the max power consumption of the whole setup is only 60W .
Q1. ) is this correct? does the whole system really consume only 60W
Q2. ) is this the psu input value or output value ?

Thats at the plug. Meaning everything in that PC uses a total draw of 60w from the plug in the wall.

^ok.. this is really really good. 60 W at the wall is a bit unbelievable considering taht most rigs go at about 200-300w , atleast thats what everyone says..

Thanks all for replying ,specially badtrip

One last question
Here is the setup that consumes only 60W at load-
CPU II Intel Core 2 Duo E7200 (45 nm, 2.53 GHz, 3 MB L2 Cache)
Mainboard II Gigabyte EG31MF-S2, Rev. 1.1
Intel G31, BIOS: F4g
RAM 2x 2 GB DDR2-1066 Chaintech AU2G732-12GH001
HDD Seagate Barracuda 7200.11, 500 GB
7,200 RPM, SATA/300, 32 MB cache
DVD LG GGW-H20L

Can a laptop like external 80-90W PSU be used for this ? Ofcourse the necessary connecting wires would be absent in an external PSU.
