What kind of power supply do I need?

This question is most likely for the PC power supplies, but just in case, we do have many kinds of USB power adapters, including car chargers, USB adapter cables, and Wall Outlet USB adapters. We have a selection of iPhone/iPad/iPod power accessories for your car and home as well. And if that isn't what you're looking for, then try our general power adapters that could help you power other types of devices. Along with the chargers and power supplies themselves, we also have items that could prove handy for automating power output or controlling power outlets remotely.

As to your computer power supply unit (PSU) needs, there are several options to choose from. We have a broad selection of ATX power supplies ranging from around 250W to 1200W, making sure that there is a power supply for any customer. A standard office-use PC will probably not need much more than a 380W power supply. Then we have mid-range PSUs for those that like to have a bit more power in their hardware, often system meant to be able to play some games as well as edit photos and video, or other similarly taxing functions. Then as we get closer to 600W and above, we reach the performance level for gamers, over-clockers, and other power-users and computer enthusiasts. These power supplies can support multiple video cards and the latest and greatest hardware with many connector cables and large cooling solutions.

How do I know what power supply to buy?

The type of power supply you need is dependant on whether you are starting a build or replacing an old power supply in your current PC. If you're starting a build, then you'll need to consider the energy consumption of the hardware you'll be installing. For home office or small office systems, you won't need a ton of power, as you'll have a minimal amount of hardware to install. As the systems get more hardware to install, or as the hardware becomes higher performance, it will likely need more power, requiring a power supply with higher output and stability. The 80 PLUS Certification is good way to tell if the power supply is reliable, especially for systems that are going to be running more taxing applications, or for long periods of time.

If you're looking to replace a power supply in a pre-built system, such as a branded one that you've bought from a retail store, then you'll likely need to find out the model of the power supply in your system. While many can be replaced by an ATX power supply with the same wattage and connections, there are a lot of brands that create unique form factors, requiring the same model, or generic version of the model, be purchased as a replacement. We do carry many of these, but we know they can a little more difficult to find so if you would like some assistance, feel free to contact us.

Do we have any laptop/notebook power supplies?

We have many laptop power supplies for brands such as Lenovo, Gateway, Acer, Sony and many more. If you can't find a specific model, we also have many universal Lapotp AC Adapters, with multiple tips for compatibility with several types of notebook PCs.

How do I know if my power supply works?

If you are installing a new power supply, or if there is an issue with your computer hardware getting power, try using a PSU tester to determine if the power supply operates properly. If so, then it's good to install, or in the case of a hardware issue, can likely be ruled out as the source of the problem.
