I just bought an AT3IONT-I Deluxe a week ago for a new build. I'm still putting the machine together. I've had a lot of problems with the build, but I'll tell you what I know, and maybe someone can give advice on the problems I'm having.
The board has a molex connector, with pins, not holes. (I think this is unusual.)
It comes with a cable that attaches to the molex, and has 3 SATA power connectors. I hope to get four SATA drives working, so I bought a SATA power splitter. (I bought this board because it has four SATA data ports.)
The molex splitters I've seen won't work because the board has pins, not holes.
I don't have the machine in front of me now, so I'll post the stats on the bottom of the power brick tonight.
My drives are an Onyx SSD, a full size Optiarc DVD drive (noisy monster), and two Western Digital Scorpio Blue 2.5" drives.
It's all squeezed in a Morex 6610 case, with one Scythe slipstream 120mm 800 rpm on top. The board's BIOS has an option called 'q-fan', which I use to run the fan at around 580 rpm. It's nice. When the two notebook drives spin down I can't hear a thing unless I stick my ear on the case. It's seriously quiet.
The bad news is, I can't get it to work.
Windows XP freezes, and I got one error running memtest86 overnight.
Linux runs fine though...
I have two ideas:
The Onyx has some new firmware, which I just flashed to the drive last night. I had to erase the drive to do it, and so I'll have to reinstall my OSs later. I think it might fix the freezing, but I don't think it would account for the error in memtest.
Power may be an issue. It just occurred to me today that I got the one error in memtest while all four drives were plugged in, but it ran fine after I removed them. It could just be coincidence. I'll investigate that tonight as well. The AT3IONT-I uses DDR3 RAM. I'm using some rated at 1.35v (G.Skill ECO). The board lets me set the voltage that low, but it might be more stable at another voltage. I'll try that too.
I'm pretty sure that heat _isn't_ an issue. The cpu hasn't ever gone above 35c, and the case is full of holes.
Sorry to ramble.
I hope I answered part of your question, I'll find the stats on the power brick for you later.
If anyone has any ideas about this I'd love to hear it.
