Power Consumption

Comparing power between these systems is a difficult task since none of them use the same power supply. The ASRock and Zotac systems use their own external DC power supplies, while the ASUS relies on our standard testbed ATX PSU. The Zotac PSU is a 90W unit while ASRock uses a 65W adapter. The higher wattage Zotac PSU actually ends up being more efficient than the ASRock unit, drawing 23.8W at idle and 30.2W under load. The ASRock system draws nearly as much at idle as the Zotac does under load, but both are well under 40W.

Load Power Consumption - Quantum of Solace Playback

Since we’re stuck using a traditional desktop PSU, the ASUS board draws significantly more power. Even when we went down to a 300W unit we still saw power consumption above 40W. Without any specific low wattage mini-ITX PSUs on hand, this was the best we could muster.

Technically Zotac wins here as well, although things could change if we had a very efficient low wattage mini-ITX PSU.

    ASUS is messed up in this respect the last a8n-e board I used had the same stupid issue a small fan that was loud and broke down easily on the south bridge. It must be a cost issue but it causes more problems then its worth. I replaced it with a passive heatsink rather then getting a free one from asus cause I knew the free replacement would not be much better. Reply

    Put the bluray drive all the way at the top, make the case 1 to 2 cm deeper and or higher and put a row of low rpm 60mm fans in the front. You could get two to three times the airflow and it would be quieter. Also, why have the restrictive punchouts in the back for the rear fan, seems you could open that up much more. Punch more holes all along the sides or in the blank area in the back. Reply

    I agree with this. These smaller devices are meant to be placed on the desk and are pretty close for the user. I wouldn't mind having them at a bigger size if that's what it takes to bring the noise level down. Reply

    The hard drive beside the ASRock ION 330 is not what comes with the unit. It ships with a 320GB notebook drive, and not a 3.5" desktop drive. Reply

    The hard drive was just included to show the small size of the machine, I'll clarify in a caption :)

    Take care,

    I don't think this was mentioned, but Asus has also introduced an Ion-based EeeBox, which is a complete system.

    Anand, you think you could request a sample?

    That unit looks sweet. I stumbled on it over the last two days and am planning a Windows Home Server based on it.

    Looks to be fanless, 330 w/ION, eSATA for additional storage, gigabit Ethernet. A perfect WHS "appliance" for my house.

    Just requested it :) Waiting to hear back from ASUS on their plans for this thing in North America.

    Take care,
