PC Power Supply

When it comes to the internal components of a PC, power supply units (PSUs) can often be overlooked by ‘cooler’ products like a graphics card or CPU. However, PC PSUs are incredibly important to the running of your computer. After all, if your PC doesn’t have enough power, your high-performance components simply won’t work. At Inside Tech, we have a wide range of power supply units to choose from, with wattage available from 500W to 1600W for the biggest, most powerful gaming PC setups. All this power is likely to produce a lot of heat within your PC, but don’t worry as many of our PSUs come with built-in cooling fans to ensure they never overheat. If you have any questions about our range of PC PSUs, don’t hesitate to contact Inside Tech’s friendly team today. One of our experts will be happy to talk you through our range.

The most important aspects to look for in power supply units are wattage output, cable type and efficiency rating. You must have sufficient wattage output to power the components in your PC, while the efficiency is marked by a score of 80+ followed by a material, such as titanium or silver.

Cable type is also key to powering your computer properly, as it determines how you integrate the power supply unit into your PC. The choice of cable type can also depend on your experience; a novice PC builder may choose a non-modular or semi-modular cable type, which is a more simple installation. An experienced builder, on the other hand, may opt for a fully modular cable type. This allows them to pick and choose which cable to use for other components.
