Power supply 


On the back of the power supply may have a red power selector (some have it and some don't). Make sure the selector says 115. If it is on 230, the system will not come on and may damage the system. NOTE: Before changing the selector, remove the power cord and push the power button for 5 seconds to discharge power.

The power supplies come in different wattages. 200, 250, 300, 350 and so on. The systems will work with the 200 watt power supplies, but if you are connecting numerous devices to the system, it will make the power supply work hard. It may not provide enough power to all devices if many devices are connected (I haven't seen that but it is possible).

Another thing to consider is the usage and surges. Electricity is never steady. It fluctuates. If you have a low end power supply and you take a surge, it can damage the power supply due to not much room to spare. The larger power supplies can handle the surges better. If you replace the power supply it would be wise to get a higher end power supply for this reason.

Most computer systems can take generic power supplies. If that is the case, you can buy one at a local computer store. Just make sure you get the right one. If you have an AT case, get an AT power supply. If you have an ATX case, get an ATX power supply. The type of power supply is usually labeled on the power supply.

There is cases with custom power supplies and on those, you will not be able to use generic power supplies. See the manual of your system or contact the manufacturer.
