Two New Ions: ASUS AT3N7A-I and ASRock Ion 330

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.
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.

Hi,at least here in Germany the AT3N7A-I is officially sold with the noisy 6000 RPM fan. Totally unacceptable...
Bye,

Very usefull rewiev, but i don't understand where is diffenrent between Asus and Zotac board for the 20% power consum diffenrent.Asus Express gate looks very good. But the power consum and noise fan is terrible.
When is poblem? Same CPU, same Chipsets and Asus takes 19W(?) more.

A thousand Thaanks on effort writing this article and all the troubleshooting and also all the great help on sending bck faulty reports on behalf of us.Your enthusiasm on technology and service were greatly appreciated.
Thanks again.
best regards,
Abby
THG S**Ks hard~!

Why not just use a celeron E1400 for $40, and maybe even overclock it?And yes, I would still trust my $50 ebay P4 865g system over one of these things. 166MHz FSB isnt just stupid, its like a sick joke.

> Why not just use a celeron E1400The Atom CPU's lower power is the point of these.
You can also purchase the ITX boards with socket LGA775 or AM2 if you want a faster processor, but at a major increase in power use.

Trust? These are the same components as found on ATX boards, just a smaller form factor at 17cm x 17cm. ITX is designed for smaller size and lower power. Compare it to like buying a Mac Mini.
> 166MHz FSB
The Atom units are 533 FSB. Look at the "Rated FSB" value on CPUZ. The Bus Speed will be 1/2 for a two-way and 1/4 for a 4-way interleaved memory system. The regular ATX systems are the same for their FSB. You may wish to dl a copy of CPUZ and run it on your own system to see what the numbers mean.

Sorry, fingers working faster than brain and no post edit... :-)DDR = double data rate, so 133 clock = 266 DDR freq, 2x interleave = 533 FSB, if I recall.

I've been using an Atom PC for my surfing system for quite some time now. It has the Intel 945GCLF2D, 2GB RAM, Kingston 64GB SSDnow, in an Apex MI-008 case. On sale all the parts cost me about $300CDN. The case is 8.5"W x 12.5"D x 5"H (just slightly larger than an APC ES750W brick UPS), supports 2x 3.5" and 1x 5.25", and includes a 250W internal PS. It would work for a HS or HTPC since you could fit an SSD OS drive, a 1-2TB HD, and a DVD.I pulled the noisy fan off of the mobo and put a Noctua 80mm fan with the silencer connector (970RPM) blowing across the board from case vent-to-vent. It's so quiet you can hardly tell the system is on (it's half as loud as just a 3.5" HD's noise). The CPU runs at 25C, mobo at 40C. Temps go up by only ~5C under full load in Everest etc.
I'm running Windows 7RC and Kubuntu on it. Ubuntu (Gnome) is just too slow on the video. KDE performs not bad. But W7RC in Aero performs well, even on the GMA950. It is not as fast as my C2D or C2Q workstations of course, but it does ok for surfing. I also have a HS and HTPC but both of those are using C2D ATX, I personally wouldn't use an Atom for those since I prefer more performance, but for general surfing and a low-power system that I can leave on for downloading I don't care.
I'll probably upgrade the mobo sometime in the future to get the better video. I really recommend the small size and low noise of the Atom.

I want to build a server/HTPC combo, thing is it will have to be in my home and I can't get proper rest with a fan humming in the background.I was thinking, would it be possible to build a completely fanless system using the IONITX-C-U? Using an SSD and the external power brick would give me a system without any moving parts. But what kind of temperatures would such a system generate?

Asus and Asrock have repeated the exact same mistake that prevented me from considering the Zotac - Only three drive connectors. My MiniITX file server requires four: One for the SD Card reader, one for the optical drive, and two for the RAID1. The only Ion-based board that I know to support four drives is the Point of View Ion 330.strikeback03 - Monday, August 31, 2009 - link
There are USB headers that can be used for a card reader
