I've looked at the sticky about recommended power supplies and that was certainly helpful. I am not a gamer but use my PC as a server and have several internal HDD's connected and need to upgrade cooling as a result and am concerend about taxing the 300 watt supply the PC came with.
Can I just swap the CPU with my existing without replacing all the cables?
Is it better to use the cables that come with the new CPU?
Does the wiring need to be consistent with what I have now...several leads for HDD connection?
