I have a Gateway DX4850-45 computer tower I have never changed a power supply and watched a bunch of videos on how to do it I thought that it wouldn't be that hard until I looked inside of this particular computer The components are pretty cramped in there and there is a lot of other wires I haven't seen Its kind of a mini board or something I wanted to upgrade my graphics card because this computer has integrated graphics which aren't very good so I got a xfx radeon 6770 and it calls for more power than what this computer came with 300watt so I bought an antec 620 from newegg I got the computer apart and I was tracing the wires coming from the power supply when I noticed what looks to be a wire with a little clip that when I pulled it apart has two little clear looking fingers that snap into it I don't have a clue as to what this is I never saw one of these on any of the videos of people changing their power supply and I don't see anything like this coming from the new power supply I just am wondering if anybody can tell me what this is This computer does have a blueray drive I would appreciate any help Thanks
