I replaced the poer supply, but I had to pry the stuff out with a metal piece on the back that is used to cover the unused PCI e ports. the plastic pieces on the moterboard have come up a little but the pins are still in place. I think I was pushing on the clip hard enough... I had to break the clips. It was an old PSU with a wattage that was too low for my upgrade so I didn' tneed to leave the cords in tact. can you normally just pull them out with your hand?
