Unable to locate the appropriate PWR pins for an OEM da061/078l-AM3 motherboard.
Unable to locate the appropriate PWR pins for an OEM da061/078l-AM3 motherboard.
I'm facing issues finding a detailed guide or schematic for the pin configuration on the front panel of this motherboard. I've confirmed that the components I've connected are functioning and positioned correctly. The reference image you mentioned with two power switches didn't activate the system. It appears online manuals for this board are either restricted by paywalls, subscription fees, or require cookies to access. Acer no longer provides a manual for this model.
The board doesn't appear to have a pin layout matching the top section of the first image. This might be because of the specific board revision illustrated in the second photo.
When working with Rev 3.0/5.0, locate the marked SW1 on the board. The headers listed below should indicate their positions. You might have a merged header setup, where what appears as one header is actually two separate ones combined. I suspect there could be a split header at the lower right corner of the board. The inner section of pins matches what you’re searching for. Based on the pin count and arrangement, the area with a blank space followed by two rows of two pins seems to correspond to SW1. If you can’t locate it, someone familiar with the schematic might help—this could take some time. The board model appears to be DA061/078L, with 08120-2M underneath. The third set of numbers shows 48.3V801, and the rest are unclear. A clearer image was found, revealing a single pin in the gap that aligns with SW1 by both count and layout. You could try connecting the two pins in the top left row next to the gap (pins 6-8) to test functionality.
Thank you! It seems I might be missing the pins labeled "SW1" due to the setup I'm using. I have the motherboard inside a cardboard box with cables, which is making it harder to see. I did notice the set of pins with a white base at the bottom right in the image. I also tried connecting it with two power connectors using pin 6 and 8, but it didn’t power on. Additionally, my board looks similar to the one in the picture, but it’s missing the 4-pin fan connector on the bottom left. I’m not sure if this matters much, but it might indicate a different revision than shown. I plan to take a photo of the board or system and share it here.
I located it! I searched online using the model numbers and pictures you shared, and found a matching image. The pin layout on this board matches exactly what I saw before. Now the board is working properly. There are still some issues, but I’ll follow my usual troubleshooting steps to fix them.
Hey, are there any cooler options with a larger contact surface for that board? I was looking into getting a Noctua mounting kit for one of their fans, which seemed to fit well, but they mentioned the 72 mm mounting hole spacing isn’t standard. They also noted from an old Acer X3300 that this setup isn’t typical. On your photo, it looks like you have a different design than the original cooler I had installed. If you need full CPU coverage without leaving too much exposed, I’d appreciate knowing if there’s something available. Thanks for sharing the details—I figured out that the socket coolers match Intel’s LGA775 specs, so maybe a compatible kit exists. Also, I’m considering recycling it for melting down later. Cheers!
