Okay, so I want this video card http://www.newegg.com/Product/Produc...82E16814133199
which requires a 350W power supply. I currently have a 305W power supply. I have a Dell E521 computer, running Windows Vista. I want to buy this power supply
http://www.newegg.com/Product/Produc...silencer%2b360
which is 360W, fulfilling the requirement of the video card. I've installed one video card in my lifetime, my question is, how hard is it to take out a power supply and install a new one, as well as connecting all the wires? Better yet, is there instructions for this, or how should I go about doing this? Thanks for your help.

The easiest way when replacing the power supply to know where the wires go is to look where the wires are on the exising power supply, you will see there is a large plug going to the motherboard, possibly a 4 pin plug going to the mother board also, 1 going to the floppy drive if you have 1, the remaining plugs will all be the same 4 pin plugs, these are for your dvd/cd drive(s) and hard drive(s).
If you need to, draw a diagram of how your current power supply connects you and identify the wires on your new power suppy and label them.
P.S there should be 4 screws which hold your power supply in your case, just undo these and your new power supply will attach in the same way

You should have no problem replacing the supply, just unplug the connectors and remove 4 screws and pull the supply out. Don't forget the little 4 pin plug, it will only fit one way so don't worry about getting it wrong.
