Is there a difference in the power consumption between DH87RL and DH87MC?
The c't magazine has build a 10W PC with the DH87RL:
Intel Core i5-4570
SSD Samsung 840 250 GB
Enermax Triathlor EWL300AWT
Will I have the same energy consumption with the DH87MC?
It offers more upgrade options (Slots).
Is there a motherboard that consumes even less energy?
Tobias, definitely an ATX motherboard will consume more power than a Micro ATX since it has more chipsets and memory DIMMs included on it.
The difference between the two devices is not significant; it will depend on the additional components that are being installed on the board itself, like the processor, memory, video card, hard drives or SSDs.
The following information can be found on the TPS of both motherboards (page 56 or 57)
No, I mean by the same configuration.
Only the boards withe the same "Intel Core i5-4570" CPU, two 4GB RAM, and without additional cards.
Only onboard grafic and sound.
The whole computer with DH87RL mainbaord needs (including SSD Samsung 840 250 GB hard disk) only 10.3W.
I mean only the idle :-) .Only at idle pays to compare.
