I have been using an AM1H-ITX motherboard using its dc input for close to 2 years as a HTPC. 5 days ago it shut off while watching TV on it. It would no longer power back on although the USB devices (bluetooth, dvd drive) were still getting power. I tried a standard 750w psu I had lying around and it works fine on that. I figured the power adapter (90W) was no longer working properly, so being in a hurry picked up a universal laptop power adapter (also 90W) that had great reviews from a local store. Same result as my current power adapter in that usb devices get power but the system will not turn on. At most one of the fan twitches for a split second. I assumed something was wrong with the DC connection on the motherboard and figured my options were to use a different psu or replace the motherboard. I decided to get a 90W picopsu which was just delivered. And.... same result with usb getting power but system will not turn on. The picopsu is 20pin ATX connector while the motherboard has 24pin. I found lots of people saying that usually is not a problem so gave it a shot. I am not sure if that is an issue with this mobo. What it seems like though is the system might all of a sudden be drawing more power than it should be and somehow 90W is no longer enough? No idea how that would happen but I don't know what else to think. It is a very basic system with only one ssd. I have tried with all usb devices unplugged. Really hope someone has seen something like this before but given the lack of mobos with DC ports I am not sure that will be the case on this forum. I will contact ASRock support as well right after posting here. If necessary I will order a new motherboard. Not a big deal since these boards are fairly cheap. It is an OEM Windows license so not sure how easy getting the new board activated will be. It is in a tiny case with no room for a PSU and I don't want to get a bigger case. update: Well I never got any replies here or from e-mail ASRock support so just went ahead with ordering a replacement motherboard. Swapped in the new board and everything is working fine again. Disappointed ASRock never sent any kind of reply so probably my last ASRock board. |

" rel="nofollow - Sorry for digging out this old thread, but I seem to be having the/a similar issue, so I was wondering if there is any solution for it by now? For me the board/pc doesnt boot up when using the 19V Supply (tested with different, working supplies), but does boot when using an atx power supply. (So far I could only test with a 20 pin, didn't power my sata drive)

Doubt it but I haven't looked online myself since replacing the motherboard. Honestly these motherboards should be given an extended warranty given the clearly defective DC ports. Seems to be a question of when rather than if it will fail. I had unfortunately built a system for a friend using this motherboard too and while his lasted longer than mine, that motherboard had the same DC power failure and he had to buy a new atx power supply and case to fit it in. That was awhile ago now but still by that time these motherboards were no longer being sold (not like I really would want to buy another defective motherboard anyway). |

Thanks for the fast response! That's more or less the dilemma I was expecting, should I buy a new board, an atx-supply or move to a different system... Reading that the DC port is the weak spot of that board, buying a new board just for being able to use a universal DC Supply seems to be the least attractive option. Anyway, thanks again! |
