D201GLY2 Power Consumption

**Stealth915** · 05-06-2008, 04:43 PM

I'm doing some research on exactly how much power my setup will need, and I have some questions on the D201GLY2.

According to the Intel spec sheet (page 48)

it consumes 15W at minimum loading, and up to 180W (!!!) at max loading. Now, max loading assumes there is a 500mA draw on the 5V rail for each of the 6 USB ports, which is highly unlikely. But even taking away the 3A x 5V = 15W draw from the USB, it's still 165W at max load.

I know 165W would be a worst-case scenario, but I don't have any other numbers to work off of. Does anyone know what the typical operating power of this board is under "normal conditions"?

Depends on the processor you use, unless it comes with a builtin CPU?

The D201GLY2 comes with a 1.2Ghz Celeron 220 that has a 19W TDP. I am interested in the typical power consumption of the entire board as a whole.

I don't know the answer, but I would say that it will probably stay below the 165 just about all of the time. If you don't use all of the disk ports, don't max out the USB, and don't use the PCI slot, you will always be below 165. You may want to have a separate powered USB hub to offload the USB devices' 5V supplies. You can also turn off onboard features to conserve power.

I have a ton for crap hooked up to the earlier version. Every USB port is taken including two power hungry devices, a Powermate and a high powered Engenius362ext USB Wifi Dongle, also a Belkin USB Bluetooth Dongle. All USB ports are used including an additional non-powered USB hub in the glove box. I have my Lilliput, Fusion Brain and Audigy 2NX all hooked up directly as well.

1GB Ram
your standard 3.5 160GB Hard drive.

The power supply is an Opus 150w which is now 3+ yrs old. Works perfectly, no issues at all in winter or summer.

Hope this helps as some sort of gauge.

Thanks, that does help!

It sounds like the board doesn't use anywhere close to the max load power. I'm planning on going with the M2-ATX and hopefully it'll be enough.

im running mine on an 80W psu

USb wifi
USB blue tooth
USB GPS receiver
1 laptop hard drive
no optical drive

survives crank no probs too

Guys, I'm using the D201GLY2 in a commercial project (anticipated volume at least 1000 per year) and did my homework with respect to the power draw of the D201GLY2.

Even during stress tests (cpuburn etc.) I never saw the D201GLY2 consume more than 40W and, in fact, in my design I am running it off a 55W ATX power supply. (Which doesn't seem to available in retail, sorry.)

In other words, if the D201GLY2 ever consumes more than 55W in the field, and the power supply shuts down, I'm out of a job.

thanks for all the replies. I feel a lot better about getting a M2-ATX now. it should give me enough overhead even with a harddrive/dvdrw/pci sound card/usb devices attached.

Quick offtopic clarification needed about powered USB hubs:
The point of having a powered usb hub is so that the total current draw of the devices on the hub is not limited to the 500mA available on the single USB cable going to the Mobo - but since the hub will be getting powered from the 5V line (i'm assuming from the M2-ATX somehow) it will still count towards my system's total power draw (on the M2-ATX).

This makes sense to me in my head, can somebody verify that I'm not missing something?
