idle power consumption server/gaming

[SirTech]

Hi guys,

 

power consumption in Europe is rather a big topic.

Right now I am running the following hardware (servers are running 24/7)

 

Servers:

MacMini C2D = 30W (idle)

Fujitsu i5 2400 = 34W (idle)

 

Gaming:

i5 3570k@4,5GHz + 980Ti = 49W (idle)

 

For the server that makes 0,064kW * 8760h/a * 0.24€/kWh = 134.55€/a

 

If I only could lower the idle power consumption on the server side by 50%.

There are two option for doing this.

 

1)

Sell the Server-hardware + some from the gaming-machine to do the following.

Use unRaid where I have one gaming vm that will get assigned the GTX 980Ti.

For 24/7 I need a Sophos UTM 9.x + NextCloud + test-CentOS + Windows 10 Dev Env. as vm on this machine.

My hope with this scenario would be that if I turn the vm down, the GTX 980Ti wont drain too much power.

• i7 6800K
• X99-Board
• 16GB Ram (already in hand)
• 2x500GB SSD (already in hand)
• GTX 980Ti (already in hand)

 

2)

Sell the Server-hardware and buy this:

• Xeon E3-1235L v5 (max. 25W TDP) or 1230 v5 (max. 80W TDP)
• Supermicro X11SSH-LN4F
• PSU
• Case
• 16GB Ram (already in hand)
• 2x250GB SSD (already in hand)

 

For the first scenario I will have to spend +- 0€ after selling most parts of my old systems.

But the second scenario is a rather expensive one because I will only get around 300€ for selling my old hardware and have to spend around 700€ for the new.

That is why I came up with a third option:

 

3)

• Xeon E3-1230 v3 (max. 80W TDP)
• ASRock Z97 Extreme 4
• PSU
• Case
• 16GB Ram (already in hand)
• 2x250GB SSD (already in hand)

 

The problem with scenario 1 is: I have no source for a real idle power consumption. Same goes for the second scenario though I think the Xeon might have a lower idle power consumption compared to Broadwell-e.

Which option would you go with and why? Maybe you have some advice or at best a source where I could look up power consumption scenarios. I don't get why there is no database with proper measurements.

 

Cheers

Keep in mind that even if you go with a lower TDP chip, there are still overheads in the PSU, in the motherboard, and the other components, at idle, which will still bring you into the 30-40W (or higher) range.

 

Do you have a good meter?  Like a Watts Up? Pro .NET?  Quite frankly, if you can get a full-sized server into the 30-40W range, you're doing darn good. 

 

24 euros per kilowatt hour, that's whacked.  Maybe consider virtualizing whenever possible, so you can have it all running on the same physical machine.  Solar panels?  Can you save electricity elsewhere in the house?

0.24€ at 24€ Europe would go dark

 

PSU would be like in my gaming rig a Sea Sonic 520FL or for the Server option a 400FL. Or if there is an even better PSU with higher efficiency.

The meter I use is a good one.

 

For the motherboard I choose the ASRock Z97 Extreme 4 which draws just 3 - 5W.

The Supermicro - no idea! You won't get anything about this hardware. That's my problem

I should start a power consumption database and measure everything

[Mark77]

Lol, .24 euros per kilowatt hour...  haha.  I don't know if Supermicros are bad or not.  I've seen nothing on my X9SAE-V that makes it appear any worse than the others.

Okay so i did a little bit more of research and what I will go with is this:

 

i7 6700

ASRock Extreme 4

16GB DDR4

2x500 850Pro

GTX 980Ti

 

I guess this will get under my 50W.

If not I'll give back the i7 6700 and go with the 6600K

 

And buy a Zbox CI321 or 521 with enough power for most of my vms and a lot of power saving

I don't know if the "t" series cpus idle lower but they are usually 35w max tdp.

[SirTech]

Idle seems to be the same.

did some research on t and s models as well

thats why I'd go with the non k

 

Just bought the ci521 for testing purpose - want to know what the throughput with this thing and utm is!
