ATX Power Connector is bent
Some of the ATX Power connector pins are bent on my ATX power connector so it won't fit into the motherboard. Any advice on how to bend them in to shape? I can't show you a picture of it but this is what it's meant to look like. http://www.google.co.uk/imgres?q=atx+power+connector&num=10&hl=en&biw=1024&bih=677&tbm=isch&tbnid=pBxw72UuNQeF2M:&imgrefurl=http://pcsupport.about.com/od/insidethepc/tp/atx-pinout-power-supply.htm&docid=wGFiE8B7QPgj8M&imgurl=http://0.tqn.com/d/pcsupport/1/0/1/7/-/-/atx-24pin-molex-39-01-2240.jpg&w=702&h=1024&ei=bDX0T6WxIc-k8gOotOWVBw&zoom=1&iact=hc&vpx=519&vpy=295&dur=5451&hovh=271&hovw=186&tx=99&ty=171&sig=106734126604990011859&page=3&tbnh=155&tbnw=99&start=31&ndsp=18&ved=1t:429,r:6,s:31,i:195 The pins are bent on the bottom left of that picture
ATX motherboard connectors would be pretty hard to 'bend', if you mean that the snap-on ATX connector is not lining up, you can probably fix that by going in with both hands so you can hold both parts of the connector together and make it line up.
Worst case, the extra four pins are optional on most motherboards so you can simply snap it off and go with only the 20pins part.
