I have read about being careful about making things will fit and/or work together, and honestly I am a hardware noob! I am moderate computer user though, so I am not a complete noob I know a lot about computer related stuff but I have never installed a video card/power supply in a computer before.
Do you all think this will work?
And if so, do you think I could do it myself with a little effort?
Just to clarify that PSU is the same one that you got from newegg.
This video card will blow hot air out of the case, costs less and has double limited lifetime warranty.

Assuming that It is not a "slimline" PC then The new power supply is just a bit longer (35mm) than the old one, meaning that you can almost definitely put it in.
