Power wattage

Recommended Posts

Hi all,

 

My Bare Metal DSM5 is running fine (and so thanks to everybody here, specially coders/testers) based on Asus P5Q Pro, Dual Core E7500 etc.

I have 5 drives currently (10K for system, 2x1.5TB, a 4TB and a 3TB) plus CDROM for booting.

 

I'm running about 100 Watts at the wallplug. Is there anything I can do to get this to drop significantly.

Less bigger drives for sure but part that obvious thing?

Change to a HP Gen8 ? Would that really get me less energy consumption?

I didn't manage to run properly the Intel script for power saving either.

 

Thanks for your input.

 

Best regards,

Thibsie

start with a different processor, that one has alrady a high TDP of 65 watt.....

Further how many memory slots do you use ? Lesser = lesser power consumption.

 

Smaller drives ? i dont think so.... small or big all drives need to spin and need power for that. If you want to safe money there take a look at SSD's or shutdown/idle the disk during not needed hours.

 

change to HP gene 8 only makes sence if u use the xeon low power processor otherwise all result will be same

What is included in your 100 Watts?

With an out of the box system you will not get much better efficiency.

See my setup - I need below 20 Watts when drives are in hybernation.

No display attached...

So if you want to be more efficient you should built your own setup.

Important is that it fits to your needs.

So, what do you need your NAS for?

Only as File and Media-Server than a setup like mine is enough...

Thanks both of you.

 

About the drives, I meant, less drives but bigger one but worded it very poorly :wink:

You indeed confirmed this to be exact. I'll see if not powering a couple of them make a noticeable difference in power usage and learn from there.

 

I'm trying to find a low power s775 CPU but IMO it will end expensive for what it would bring.

I'll get my RAM sticks out too: 2x2GB and 2x1GB. Clearly overkill.

 

I indeed only use it for media/download, Sickbeard and accessed via media player.

For the most part. If it can do other things, great but that the prime use of it.

 

I may have to find a GPU too as I only have an old GF6600 (and the old PCI VGA I have will not boot)

 

Your 20W power usage idle is impressive.

 

I'll start from there. Thank you !!

So those are the results:

 

Pulling RAM but 1 stick, got me 3W

Pulling drives got me about 5W/drive (I have 5)

Down clock and underplot got me about 10W

Unplugging the GPU (and yes it still boots) got me between 10 and 15W

2 gigabit cards I ever pulled but were unused got me 3W

And the optical disk another 5W.

 

Of course I need all disks for now and the optical too but using a USB disk instead of optical, and replacing both 2x1.5TB and 300GB 10K drives by a 6TB or 8TB would spare me a nice couple watts too (about 15W).

 

Also I didn't pay attention earlier but I realized that the 100W I was taking about included the modem/router and a little switch.

Anyway, even now with my 5 disks, I got about 25W back. Nice work.

 

Thanks :smile:

 

 

Now, Intel CPU script and HDD suspend would be even better of course.
