(If new power supply has a 110/220 switch, make sure it is set properly) Make sure you double check your connections with everything. You may need more cables for everything, unless you reused cables from your previous power supply. Also double check that the power supply you purchased has the same voltage rating as your previous power supply (assuming it worked and then died) or more than enough for what you need (assuming that you installed many new parts). In case you're in a pinch for your CD drives (important government secrets on a DVD-rom or something equally as important), look for a little hole near the eject button on the drive. Insert a bent paper clip, pointed stick (vague Monty Python reference here, search YouTube for "Monty Python's Self Defence Class" and you'll understand), or other small, pointy object into the hole and voila! the tray should eject a bit! (you'll still have to pull it out, instead of just waiting for it to dutifully slide out). Hope this answers your question well!

External devices either require their own power supply, or they get power from a USB socket. Internal devices get their power from the power supply which is already in the computer.
When adding hardware to a computer how do you know at some point if you are in danger of not having the proper power supply for the add ons?
If your computer mysteriously restarts itself with no prompts, this is a major sign that your power supply is not providing enough power to your computer. You cannot harm your hardware by not offering enough power, so don't be worried about that. Things that spin eat up the most power, such as fans, CD-roms and hard drives. Addings lots of PCI cards don't take much power. I have 2 hard drives, 2 DVD drives, an intake fan and a hard drive cooler on my 350W power supply and it runs fine.
