I was performing some troubleshooting and found that my power supply has a 20 pin motherboard power connector and the motherboard has a 24 pin power connector. I guessing that this is probably the reason for the motherboard instability and my inability to load windows. I know it's probably a stupid question but I figure it's worth asking before I put the $ out for a new power supply. Any insight would be greatly appreciated!
Buy a new power supply....lol

Some power supply comes with the extra 4 pins separate since not all motherboards use the 24 of them. Be careful, though, because an extra 4 pin also comes on it for processor power and cannot be used for the extension part of the motherboard power. They are usually made up of red, black, orange and yellow single wires. If not, then you have to purchase a new 24 pin psupply.

You should find that there is a separate 4 pin plug attached to your power supply which can be pluged in the 4 holes left next to your 20 pin mobo socket, this is usualy used as the processor powering connector. It's easy to recognise as it looks like its been cut off the end of the 20 pin plug.

Hi you can buy a new 20 pin to 24 pin adaptor from ebay for a few pounds, or most new power supplys do have a 24 pin slot for your motherboard power let me know if you need anymore help regards steve,

The 24 pin main power connector was added in ATX12V 2.0 to provide extra power needed by PCI Express slots. The older 20 pin main power cable only has one 12 volt line. The new 24 pin connector added one line apiece for ground, 3.3, 5, and 12 volts. The extra pins made the auxiliary power cable unnecessary so most ATX12V 2.x power supplies don't have them. The 24 pin connector is polarized so it can only be plugged in pointing in the correct direction. 118 views
