P2 4 pin connector to a new psu 6 pin connector

[capricorn1155]

I am replacing a 300W Gateway Delta PSU with a coolmax 500w PSU. The new PSU comes with a 6 pin connector where the MBoard has a 4 pin female connection. I plugged in the bottom 4 males and they fit properly. the other 2 pins hang over the plug, but I only get power to the on/off switch on the front panel. None of my fans are running. What now?

The 6pin connector is for a graphics card, you have a 4pin cpu line on there check this out http://www.newegg.com/Product/ImageGallery.aspx?CurImage=17-159-040-12.jpg&Image=17-159-040-09.jpg%2c17-159-040-10.jpg%2c17-159-040-11.jpg%2c17-159-040-12.jpg%2c17-159-040-13.jpg%2c17-159-040-14.jpg%2c17-159-040-15.jpg&S7ImageFlag=0&WaterMark=1&Item=N82E16817159040&Depa=0&Description=COOLMAX%20CP-500T%20500W%20EPS12V%20%20%20Active%20PFC%20Power%20Supply

the single 6-Pin connector is PCI-Express power used mainly for video cards. Your PSU should have a 4-Pin ATX12V P4 connector just like your old 300w gateway or it may have the newer 8-Pin version (EPS) of it which should be able to split into two separate connectors and provide you with the same 4-Pin ATX12V P4 connector. As a general rule, if a power connector doesnt fit properly, never force it in and turn on your computer.

The PCIe power plugs are wired differently from the 4/8 CPU power plugs. using one in the wrong lace will result in shorting 12 volts directly to ground.

Congratulations. You now know the the overload/short circuit protection on the PSU works. You could have fried either the PSU or the motherboard.

You are correct, there was a (EPS) 8 pin plug that I separated into two 4 pin plugs. Each having 2 yellow and 2 black wires. I used that as the plug on the motherboard and it is up and running.
Thanks for the reply.
