pin layout for power connectors and other components on the motherboard
pin layout for power connectors and other components on the motherboard
Hey! I recently got a new gaming PC from a friend, featuring an ASRock B460 Pro4s/AC motherboard. The pins were unplugged, so I checked the manual for guidance, but every one I looked at seemed incorrect. After double-checking countless times, I’m still confused about the exact placement. I know my audio and USB ports should work fine, but I’m really struggling to figure it out. Right now I’m using a screwdriver to power up the system. If anyone has the right info on where to find those pins, it would be super helpful! Thanks!
If it's not your motherboard, this guide should list all the pins and headers. You can find the download here: https://download.asrock.com/Manual/B460M Pro4ac.pdf
It seems the asrock b460 pro4/ac is essentially a System Integrator version of the original board, possibly modified by companies like iBuyPower or CyberPC. The actual hardware might just be a rebranded version with some minor adjustments. The specific model you're referring to likely uses a standard board design beneath a different label. You're still trying to verify the pin layout with a high-quality image.
The header is located at the bottom right corner of your motherboard. In the image, it appears beneath the video card and below the heatsink with ASRock branding. The pin configuration is generally consistent across other ASRock motherboards, making the manual above a helpful reference. For instance, page 15 and page 29 provide detailed views. LEDs are sensitive to polarity—inserting them incorrectly won’t damage anything, but they may not light up. Simply switch off the PC and reverse the connector orientation if needed. Traditionally, connect the plug with the printed text facing outward, especially if labels are present. The power button or switches work with momentary presses; you just link the pins together when pressing. Remember to connect power to your video card and CPU, and avoid the common error of skipping spacers between the case and motherboard—ensure the case doesn’t touch the bottom of the board and that spacers are placed only under screw holes.
Thanks to all, it's functioning now. I hope I can help everyone.
