Help! Efficent powersupply or broken killowatt meter?

Post by Coderax » Thu Jun 13, 2013 12:02 pm

Hello!

I checked this pc with a killowatt meter, and got readings about 92-95W idle and about 50% CPU usage, the meter showd 95-105W. When it started up, then i got almost 160W, but then it settled down. Is this real readings or my killowatt meter is broken?
My other machine (i3 3220, B75 motherboard, 16GB RAM, 2x NICs, 500gb 5400rpm harddrive, Seasonic G360) showd about 60-70W in almost idle or little usage.

Intel Core i7 2600
Asrock H77
Chieftec APS-550S PSU
32GB DDR3, 1333Mhz
1xSSD + 4x 7200RPM harddisk
+ 4x casefan
2x extra NICs.

EDIT: another question is, if i would use Seasonic G360 with the i7 2600, can it handle this confiugration, and would it be more efficent?

That sounds about right, yes. 160w would be with the multiple HDDs spinning up, and without any power saving features active on the CPU. A 360w supply would more than handle that machine.

Sounds a little high to me..even with 4 HDDs..unless they are ancient power hungry beasts. Maybe the Chieftec PSU isn't meeting it's 80+ spec.

Yes, the G 360 would work for your build. Why not experiment and pull it out of your other build and try it on this one to direct compare power use b4 you purchase another one?

sounds about right to me, if these numbers are correct...

"7200RPM HDD spin-up power consumption: ~15W - 25W" - http://www.overclock.net/t/950803/guide ... components
even on the low side, thats a good 60+ watt spike right there...
