motherboard list based on power consumption

rouble · Post by **rouble** » Mon May 14, 2007 7:30 am

Is there a list that ranks motherboards based on their power consumption (keeping the processor constant)?

It would be interesting to see which socket AM2 consume most or least power.

I don't see any data that already does this. Is the difference in power consumed by motherboards so minimal that it isn't worth the time to compile such a list?

I remember I once saw some kind of comparison like that - can't remember where tho. Examined chipsets were for C2D's. There were differences, yes, but not dramatic and they wouldn't really affect the PSU enough/not enough thing.
Taking into consideration the heat generated by mobos - especially NB and SB chips - I'd guestimate a mobo could be drawing app. 20W itself, maybe a little less. Hard to say. Differences for mobos with certain chipsets would be minimal as it is the chipset itself that consumes the bulk of power consumed by the mobo itself.

EDIT - here it is - found it

of course,a PC with integrated GFX will consume less than discrete GPU, and lowest power integrated chipsets are VIA K8M890,SIS, nVidia 690G/MCP61 (690g uses least). SLI and nForce 4 chipsets use most.

Here's an interesting piece:

Power Consumption
5V @ 1.58A, 12V @ 2.05A, 3.3V @ 3.12A, 5VSB @ 0.32A
(IntelÂ® Coreâ„¢ Duo 2.16GHz, DDR2 1GB x 2)

That's power consumption for some KINO-9452-R11 mobo. Seems like the total power consumed by this mobo is app. 45W - correct me if I'm wrong. Or is this for the CPU + mobo combo?

Kato: That's including the CPU, which BTW isn't a C2D.

Does anyone know which of the following boards is more energy efficient:

ASUS M2NPV-VM
http://www.newegg.com/Product/Product.a ... 6813131014

ASUS M2A-VM
http://www.newegg.com/Product/Product.a ... 6813131172

I am guessing the ASUS M2A-VM, because it has the 690G ... but I am not sure.

Personally, I'd just get the M2A-VM (Which I just bought for my new PC, posting pictures later). Just because it's cheaper and comes with HDCP built-in. Which is a HUGE bonus.

If you don't mind my asking, what processor did you use (and other specs) ... and also what is your idle wattage on the system.
