The HP XE783 was the WalMart Xmas bundle computer from a few years ago. Though it is a real POS, I must admit that it has been a pretty good computer for $498USD. I do some digital multitrack recording, and though limited, it performed as well as I would have expected. Prior to the power supply dying, the only other problem was that the monitor failed after about 18 months.
I built a new computer some months ago, and now this one is used primarily for the kids surfing the internet and playing simple games, and by my loving wife to check her email while I am gaming, or reading the OCIA forum. So, it is very important that we get this computer back online.
The power supply we will be using is a Turbolink Switching Power Supply, Model LC-350 ATX. This power supply came with an Aspire X-Dreamer II case, but I used an Antec True430 in instead of the stock power supply, and kept this one on hand in case of emergencies. Specifications of the LC-350 are:
VAC Input: 115/230v
The power supply has one fan, that surprisingly is fairly quiet. It has a fair number of connectors, including SATA, (which we will not be using) considering it is a generic power supply that was supplied with a $55 case. Not enough connectors for a serious computer, with multiple hard and optical drives, but enough for the application we will be using it for.
Disassembly of the computer is fairly straight forward; there are three screws in the back of the case that can be loosened with either a phillips head screwdriver or 1/4" nut driver. The cover slides towards the rear of the case, then pulled upwards for removal.
Removal of the old power supply is also fairly simple, there are 3 phillips head screws securing it to the computer case. Removal of wire connectors is also normal, except for one weird connection to the motherboard. It is a 3-prong fan connector, with the plug being marked "fan-c". It has a blue wire (-12v) and two ground wires. We are not going to get too concerned about it at this time. Notice the clean interior of this case... ensuring excellent air flow. Unfortunately, there is no case fan to utilize this excellent example of aerodynamics.
