Suggestion for an external DC power brick

Hi,
I am searching in this forum but I am not finding the info I need.
I need to build a system with:

1) (probably) asrock n3150-dc motherboard or another under 10watt DC motherboard
2) one ssd
3) one 2tb hard disk

Which high efficiency power brick do you suggest?

Thanks,
Mario

Re: Reduce speed of 4pin cpu fan

Hi,
following your suggestions I avoided bios control and used linux lm_sensors/pwmconfig/fancontrol.
Now there is an automatic configuration script and so setup is very easy.

Now my fan spins at 800 rpm as I read in the review of the cooler.

Thansk again!

Reduce speed of 4pin cpu fan

Hello,
I have bought a "silent" low profile cpu fan.
Unfortunately even with motherboard quiet fan control it does not go under 1800 rpm :-(

I need a fan controller that reduces the rpms of that fan.

Can you help me?

Thanks,
Mario

Re: I need a prebuilt system around 10watts

I will use it as a server. If you keep it on 24h/24 after some time it hangs due to memory errors.
So, if I can choose, I will choose ECC.

Re: I need a prebuilt system around 10watts

Thank you again for your detailed reply. I am reading all reviews of current nuc and previous generation nuc. I cannot find reviews (that shows idle power) of haswell brix and zbox id18. I want to be sure that brix is really power efficient like intel nuc. But I almost sold for a nuc. Thanks, Mario

Re: I need a prebuilt system around 10watts

Ops I forgot the obvious...
Anyway idle power is better than I hoped.
Unfortunately price is a bit high.
Is there a thing like this with lower price?

Re: Smart fan controller for UPS

You are sure that you will not burn your place? Because it seems like that fan is moving some air out of the usv. If you drastically reduce the cooling, you could run into serious thermal problems. Worst case could be the overheating usv is causing a fire. So, fan swapping yes but keep up abreaonab...

Re: x86 with arm like power draw for router/server

We should have samples of that Jetway and the Intel DN2800MT in the next week or two
Great news to hear!!

I add some other motherboard I have found meanwhile:

jetway NF35-T56N / NF35-T40E
axiomtek pico100
ibt MI958
ibase MI958

This ones are based on amd G-series embedded apu at 5/9W

The motherboard is going to dominate idle power consumption. People used to get 15W idle or so with Clarkdales so Sandy Bridge is only a marginal improvement. The i3 brand has nothing to do with virtualization. If you want a server chipset for ECC and want low power consumption, going with AMD migh...

Hello, I am reading many review and I am confused: what is the difference at idle in wattage between: - clarkdale i3 (or i5) with 3420 intel server chipset; - sandybridge i3 with c202 or c204 intel server chipset. Clarkdale price is half as much of sandybridge... Thanks in advance for any help! Mario
