The computer won't start after changing the power supply connectors.
Here’s a revised version of your message:
I tried to fix my PC after changing the PSU cables. The process was detailed below. First, I powered off the system and turned off the PSU. Then I replaced the 24-pin with a 24-pin Asia Horse cable extension. My GPU is a 6-pin model but works fine with the 6 and 2 split cable. However, I mistakenly connected just a 6-pin Asia Horse cable to the 6 and 2 split EVGA cable and plugged it into the graphics card. The system didn’t boot at first, so I switched to the correct cables but forgot to turn off the PSU. When I tried again, it still wouldn’t boot. After removing all Asia Horse cables, I reconnected the original PSU cables, but the PC still wouldn’t start. All lights were on and fans were spinning during these failed attempts. The CPU light was lit. I didn’t touch any CPU cables, so I’m unsure what caused this. Did I damage my motherboard, GPU, or CPU? Any advice would be greatly appreciated!
Those wires are extensions; they work, but you must ensure they match your power supply type because various PSUs have unique connector layouts. Incorrect cables might damage your equipment.
Disconnect the power supply, take away all extension cords, remove the CMOS battery for five minutes. Reinsert the CMOS battery and turn on the device. Open the window. Dispose of the Asia Horse cables outside.
If the system functioned before you made changes, it’s likely not a major issue.
1.1 I’d confirm the plugs are installed correctly—verify each clip is snapped into the small notch on the plug.
1.2 Take out the CMOS battery, let it sit for five minutes, then put it back in during the first boot. Also look into troubleshooting options (found in your motherboard manual or by searching online for your board name plus “troubleshooting”). This might show up as a light or screen change.
1.3 On this initial start-up, ensure everything is seated properly.
3.1 Check if anything was disturbed while working on the computer.
3.2 Verify the RAM installation—remove both modules and reinstall one, making sure they click into place. Try booting again.
3.3 Disconnect and reattach the GPU carefully, paying attention to the PCIe slot release.
