Hey, let me start by saying I'm fairly new to this so please bare with me when it comes to a lack of calling things by their actual name. I'll try and be a descriptive as possible I've been using computers for a while now, I've made some small upgrades such as more memory, DVD drives, graphics cards etc and feel fairly confident so decided to build my own from scratch. I ordered all the parts, being careful to check everything was compatible with everything else and I was happy when they arrived about an hour ago all new and shiny with "that" smell. I flicked through the manuals, pulled up a few guides online and got to putting it together... everything was going fine until it came to plugging the PSU into the motherboard. I can see two power plugs coming from the PSU, one has 4 pins and plugged into the motherboard perfectly fine. One has slightly more pins and I found the socket for that too but upon plugging it in I noticed that the plug was shorter than the socket, leaving 4 squares of it empty. I made a crude diagram to explain... The "plug" coming from the PSU is slightly longer than my drawing but the white area is the same, I have 4 unused ...um... squares on the Power Socket. Now the plug does fit in fine with no effort but I'm afraid to power it on incase something goes wrong - Any suggestions? Or am I worrying over nothing?
