Multiple Power Supply Failures

By kevink ·
I have a Gateway 1400, Pentium 4, 1400mhz, 128mgb ram, 40gb HD, Windows ME, purchased 12/00. So far, I have had to replace the power supply on this machine twice in less than a year. I suppose it could just be a run of bad luck but I suspect thereis something else going on with this machine. Does anyone have any idea as to what could be the cause of repetitive power supply failures?

You need to narrow down the possibilities a bit.

Is the problem external or internal?

If your power is affected by local phonomena (such as lightning, storms, power surges), then the problem may be external to the computer itself. If you have had other devices go bad in this outlet, then it could be an external problem. If you do not experience problems with any other computer, or any other electrical device connected then it could be internal. If this has been a problem, a good UPS (Uninterrruptible power supply should help).

If you computer is overloaded with devices, then yes although it shouldn't burn out twice in less than a year, it's a possibility that one or more of these attached devices are creating an overload situation and causing the power supply to fail. Do you keep the computer and devices on when you are not using them?

Thanks... There is another computer in the house and there are other devices connected to this outlet via a power strip. Have had no problems with any of them. Also, the computer and other devices are seldom left on when not in use. I am going tocheck the power source and also check the amp rating for the power supply.

Considering what other hardware does the machine has installed on it such as DVD,CD-RW,or other hardware that the power supply may be overloading.
Contact the computer manufacturer to see if the power supply can be upgraded.

Thanks... Have already contacted the manufacturer... Depending on whom I have talked to there, they are either very helpful and courteous or totally worthless.

There could be several factors that could have lead to 2 replaced power supplies. You have replaced the original manufacturers power supply as well as one that you put into your Gateway 1400 yourself correct?

You could jsut really have either bad power in your area in the form of brown-outs or unexpected power surges. It is getting more and more affordable to get yourself a UPS system or at least a better than average or better than generic surge supressor. Do you have any electrician friends that could test from some outlets in your home or home office?

Also, an overload in components can cause a power supply to go out quicker, such as there not being enough wattage for say 2 Cdrom drives, 2 hard drives, a high-end video board, and any other external compenents that may need some of their power from the internal CPU.

Just a thought.

Best of Luck!

Thanks, your thoughts are very helpful. Although I have five other computers that have had no trouble and a couple of them have more internal components and external devices hooked to them than the troublsome computer... I'm thinking that maybe thereplacement power supplies have been "reconditioned" not new and that maybe the amp rating is not high enough. Going to check that out.

A 250 watt power supply is suppost to handle 7 devices with a 500 to 700 mhz proccesser. With newer computers you need at least a 300 watt, but I think a 400 to 500 watt is better. I have replaced three power supplys in diffrent computers because they were under powered. The cost is worth it after replacing one. You can buy a wall socket tester that will monitor voltage for about $20. But I bet its the computer.

One more thaing that can kill power supplies is heat.

Is the back of the PC clear so that the PS fan can move air out?

Is there anything blocking the vent openings on the chassis?

Do the drive cables block the vents on the supply?

Is there a lot of dust inside the PC / power supply?
Dust acts as an insulator, if the PS heatsinks are covered with dust, the supply will overheat.

Beyond that, I agree with everyone else, it is either voltage surges or device overload.
Actually, under voltage is worse for a computer supply than over voltage. Make sure that you are not loosing voltage from a daisy chained power cord setup.

Thanks, there doesn't seem to be any problem with overheating until the power supply starts to go bad... usually the cooling fan on the power supply begins to go and as a result doesn't move enough air to keep the PS cool so one problem compounds the other.
