1) Size and shape - will it fit in your case. Will the hole for the power cord to plug in be accessible.
2) How many devices to you need to connect? Will you have enough cables?
3) Wattage. The more devices you have to connect, the higher wattage you will want. Put a cheap 200 watt in a case with 10-15 devices and you will burn it up in a week. The power wattage is the main cause of difference in price. Better to spend the extra now and get a more powerful supply like a 500, then to have to come back every six months and buy another cheap one.

Each component in your computer uses a certain amount of power. It's not enough to just get a 450 watt power supply. There are three different voltages supplies by a power supply. Each of these must be able to deliver what you need. One of the biggest determinates of how much power you need is the amount of ram memory you have in your system. It's not all about devices like CD roms.

the power supply comes in different power outages.
If you are going to be running many add ons like excessive drives or large video and audio cards you will need a larger power supply so your motherboard can feed these devices.
Think about what you want and what you plan to expand to before you make a purchase. Don't under power, but don't waiste money and overpower and create excess heat

Yes. First, get enuough power (Watts) 450 W or better.
2nd, the quality of the components in the supply will determine how long it works and how well regulated the power actually is. Typically the more expensive the power supply the longer you will have it.

Yes wattage, the more the better. a 500 watt power supply is more then enough for todays pc's, If you have a smaller one then you may need to get less then that as the cases are smaller. not enough info to tell you exactly.

I like the highest wattage rating I can get - more power, less strain on the power supply.

Somebody on here also stated that you want to pick a good "heavy" one. As in weight. I guess that would mean that it is built with quality components.
Also, I agree with everyone else. You need to consider how much hardware you are going to try to run off of the thing.

the more cd drives and zip drives and cpu speed and cooling fan size and speed and....

the more bells and whistles on your computer, the higher the power supply has to be.
