From: KOS on 21 Jul 2010 15:48 Hi, I have a desktop that is making a loud noise. coming from the powersupply. I want to replace the entire power supply, I have read that I should not do this as it is dangerous and I could get electrocuted... Is this true, is this something that lay people should not do? Thanks KOS

Is this true, is this something that lay people should > not do? Thanks > KOS The output of the power supply, uses various low DC voltages. The wires have insulation on them. The connectors are designed with the intention of not letting you get in contact with electricity. Those factors are what helps with the safety. There would be more potential danger, if you removed the cover from the top of the ATX supply. If you leave the top cover in place, then there is little danger. This article will help with some background information. http://www.playtool.com/pages/psuconnectors/connectors.html Unplugging the computer from the wall, removes the input power. You wait 30 second after that, before working on the PC. That gives time for residual +5VSB to drain. At that point, it should then be safe to unplug the various cables. You do the same thing, before changing memory modules. Remove the power, then wait 30 seconds for the supply to drain, so none of the components inside are getting power any more. Before removing all the cabling, make diagrams and notes of where it all goes. It can be intimidating the first time you do it, and if you've made notes and diagrams in advance, that will make the job easier to complete. For more advice on power supplies, you need to tell us the make and model of computer, such as "HP Pavilion 1234". That way, we can get some idea what challenges you'll face. Supplies vary in quality, and the price charged, is not always a guarantee you're getting a good one. Finding customer reviews can help you find the good ones. http://www.newegg.com/Product/ProductReview.aspx?Item=17-165-023 "I bought this to replace a customers power supply. It worked for 40 days. I guess you get what you pay for." Those are the kind of review comments, that can identify the less useful purchases. Paul

NEVER keep it plugged in while working inside your computer. You should never try to repair or open the power supply unit, however. If your power supply unit (PSU) is making funny noises, you should go ahead and replace it before it causes damage to something else in your computer like your drives or your motherboard. Depending on the model, you can get a PSU pretty cheap, or if it's a killer gaming rig, you'll probably have to fork out some cash. Replacing a PSU is rather easy - 4 screws and a handful of wires. But you need to make sure it's of sufficient wattage, and you must make sure that you connect the proper wires when you replace the unit. Not knowing how old your computer is or what model, can't say what your motherboard power connectors are, whether a single 24-pin, a 20-pin + a 4-pin, or something different (my old Dell uses a 20-pin + a 6-pin connector). Obviously, the new PSU you buy needs to have the same connectors, or you'll need adapters - much more complicated, but possible. If you don't know what I'm talking about regarding pins, look it up before you buy. There are plenty of tutorials on-line. Learn what you're dealing with before you start. --- news://freenews.netfront.net/ - complaints: news(a)netfront.net ---
