A PC upgrade can sometimes involve several computer hardware even if you only intend to replace one component. This can hold true when you are replacing your average processor and video card with high-end versions. In these instances, you may need to upgrade your power supply unit too.
A power supply unit, or PSU, is one of the most essential parts of a computer system. It is the component responsible for supplying your computer’s other internal components with a safe and stable voltage power. Computer components are very sensitive electronic devices. If exposed to harsh electrical currents, they can easily get damaged.
Even though they are very vital in the operation of a computer, the PSU is oftentimes overlooked in a PC upgrade. For some reason, people just do not consider the capacity of their power supply units when upgrading their computers.
Power supplies have their limits, however. If you use a low-capacity PSU with high-end graphics cards and the latest processors, the PSU may not be able to handle the extra workload.
A high-end discrete graphics card and a multi-core processor can draw as much as 250W of power. You will not be able to safely run a computer with these components while using a 250W PSU since the power supply has to provide electrical power to your other computer components.
If you insist on using an inadequate PSU, your computer can crash. Worse, you can damage your other computer hardware. Thus, always buy a PSU that exceeds your computer’s power demands. A 500W power supply is a good choice if you plan to use high-end internal computer components.
In addition to taking note of its power capacity, also make sure that your new power supply can fit inside your computer case. Some power supplies are larger than others. You will have a problem fitting these PSUs inside your computer case especially if you happen to have a small computer case.
