A few things you should know about power supplies
A malfunctioning power supply can take out your whole computerA malfunctioning PSU can send too much power into your computer. Too much power is bad. Remember that scene in Short Circuit when Johnny 5 was fried with lightning? No? OK, well the upshot is an adorable robot was struck by lightning. His whole system went crazy, he became self-aware, bad guys were after him and it was just a mess. Now, we’re not suggesting your computer will become sentient if it gets too much power (although if it does, you should definitely contact us) but what a power overload will definitely do is wreak havoc on your whole computer. It’s quite common for this kind of PSU malfunction to cause a chain reaction of failed hardware. It’s bad news. A dodgy power supply can also send too little power into your computer. Now, you might think this is less of a big deal but it too can cause a chain of hardware failures. Less power results in slower spinning internal fans, which in turn causes a gradual heat build up. Heat can cause all kinds of damage to your computer’s components. Also bad news. So, the first thing to know about your PSU is that if you think it’s not working properly, it’s a good idea to act quickly. The second thing to know is that you need to see this movie. It’s awesome.
It’s often the first shortcut the retailers take to save on costsGiven their importance, you’d think big computer retailers would make sure they use reliable and durable PSUs, right? Sadly, that isn’t always the case. In fact, using cheap, bottom of the line power supplies is an extremely common way for the big retailers to cut their costs. This pushes a lot of additional risk on to the buyer just for the sake of saving a few dollars. Unfortunately, a sizable share of shop bought computers are powered by substandard PSUs.
It’s one of the few things in your computer which can seriously zap youIf your computer is running right, a surprisingly small amount of current will be running through it. For this reason, the risks of harming yourself while tinkering with a computer’s innards are generally fairly low. However, this is absolutely not the case when it comes to power supplies. Mains electricity is going into this thing. If it’s improperly repaired or physically damaged in some way, a power supply can give you a serious zap. For this reason, you should only trust power supply issues with people who know what they’re doing. We’ve replaced thousands of power supply units and we can make sure it’s installed properly. If you need help with a power supply installation, call us on 1-800-919-6373.
Signs your power supply may not be working properlyIt may be a power surge. It could be poor ventilation around the computer. Maybe it is just old age. But sooner or later a power supply unit will fail. When that happens you’re going to see a few things happening. Here are the most common things you’ll see:
1. Odd soundsYou may hear grinding or a rapid scraping sound as the PSU’s fans scrape against its metal housing. These sounds indicate that the PSU’s bearings are wearing out.
2. Nasty burning and melting smellsIf you smell burning or melted plastic originating from your computer, switch it off immediately and ask the advice of an expert before turning it back on.
3. Your computer crashes a lotThe fluctuating power of a faulty PSU may also cause software related problems. You may experience frequent crashes or blue screen of death errors. You may also find that your computer appears to begin its boot sequence perfectly only to fail halfway through. All these could be red flags of a power issue.
4. Your computer won’t even turn onIf your PSU has completely failed, nothing will happen when you press the ‘On’ switch. If no fan, hard drive or motherboard sounds happen when you turn the computer on, the problem is very likely power related.

Questions nerds often hear about Power Supply Repair
I saw this Youtube about how you can open up your power supply and fix it. Is that safe?
It’s only safe if you know all about electricity and are familiar with electrical repair. Serious juice runs through this hardware and if it’s not repaired properly you could get a serious jolt. We recommend you take this kind of problem to an expert.
I just got a computer upgrade. Do I really need to pay for a new power supply when the old one worked perfectly?
This really depends on how much heat your new computer rig will put out. A more powerful processor, in particular, is going to produce a lot more heat. You may need enhanced heat management to protect it.
