PLEASE HELP! Plugged in wrong ATX12V Cable!

[zachmullin]

Hello,

Today I was redoing the cable management on my computer today (no parts added).  I ended up plugging the wrong part of the ATX12V cable into my CPU power socket (see attached image, circled port is the one I plugged in), and unfortunately ended up booting it up a few times (I originally thought it was drive issue).  There was no signal coming from both the CPU graphics and the graphics card.  After realizing that I plugged the wrong part of the cable in, I immediately removed all power connectors on my computer.   It is an Intel Core i5 4440.  I am not sure what to do and I need advice (if there is anything I can do).

 

Thanks very much.  I really appreciate it.

 

Edit: The CPU socket is a 4pin.

if it's an 8 pin socket, simply plug all of the connectors in and you'll be fine

it sounds like you only plugged 4 of the 8 in, so your CPU wasn't getting enough power

Its a 4 pin.

The pin-outs are identical on both, so as long as the 12v rails were on the right side you're fine. I did it once sideways, luckly my system didn't boot.

 

Once everything is connected up correctly again, just turn it on.  Nothing you can do now, just plug and pray. Usually motherboards monitor voltage, and give big blaring errors if they are wrong.

Okay.  I tried booting correctly once or twice, but I'll try again.  Thanks.

Can try clearing CMOS too.  If that doesn't help, do the standard troubleshooting route, disconnect everything and put one thing back at a time.

Thanks, will do.

So far no luck.  Unplugged and replugged everything.  There is no way to reset the CMOS without entering the BIOS.  All fans spin, GPU light on, hard drive light on.  I have no idea what to do.  Tried GPU and CPU graphics.

Check your manual.  There should be a pin you can short out to reset the BIOS even when the computer is powered off.  I am not sure if it is still applicable to new PCs, but in old PCs, you could take out the backup battery and the BIOS would reset.

This. There is ALWAYS a way to reset the CMOS without having to enter it. Usually by way of a pin on the motherboard, or button somewhere.

That said, it is possible that something has already been shorted out or fried from the first time you started it.

 

If possible, could you unplug all power from the system (power supply wall power and usb devices) and take some pictures showing us exactly how you had the 4pin connector plugged in the first time? This will help us know for sure whether or not something was shorted or if its a coincidence and something else is the problem.
