Find the Right PC Power Supply at Overclockers UK

If the motherboard is the heart of a computer, then the computer power supply unit is most definitely the lungs. While not in plain sight, the PC power supply unit is one of the most important parts of every computer, and one that should be considered carefully when building or buying a new PC. At Overclockers UK, we believe that buying quality components is essential to ensuring the longevity of your computer. With this in mind, we advocate buying a reliable and good quality computer power supply is key to running a stable PC. We stock a vast range of power supply units from leading manufacturers in the industry, including SuperFlower; Seasonic; Cougar; EVGA; Corsair; and be quiet!, to ensure that our customers have a choice when it comes to selecting a computer power supply.

Buying a PC power supply

There are a number of things to take into account when looking for a PC power supply. Firstly, it's important to know what a power supply unit actually does. A PSU does exactly what the name suggests – it supplies power. It converts the voltage of the power from an alternating current (AC) into a more usable direct current (DC) that is used by various PC components. Computers use switched-mode power supplies. These high-frequency switching mode computer power supplies are directly rectified and filtered to obtain a DC voltage. The DC is then switched on and off at a very high frequency and passed through a high-frequency transformer. The speed at which this switching occurs allows for transformers and capacitors to be greatly reduced in size, and greatly increases the efficiency of converting electrical power.

Next, you should understand a bit more about the wattage of a computer power supply. A PSU with a higher-wattage can supply more power, and a standard desktop power supply can put out between 200W – 1800W. But what you should keep in mind is that this is the maximum power that the PSU can handle. The power consumed by your computer is determined by the components and not the computer power supply. A PSU's wattage rating indicates not its own power consumption, but the maximum amount it can provide to your system.

Efficiency

When you buy a computer power supply, efficiency is one of the things that should be seriously considered. The efficiency of a pc power supply relates to how much power being pulled from the grid is successfully being converted from AC to DC. You should always strive to buy a power supply with at least 80% efficiency. The number one reason for this is that it puts less of a strain on the environment by having to generate less electricity. It would also result in less heat being produced which means there will be less fan noise, and you would spend less on cooling your PC. A by-product of both of these points is that you would save money on monthly energy bills. Take a look at our range of "80 Plus" certified power supply units to ensure that you're getting the most efficient power supply for your money. These certifications are further categorised into tiers – Bronze, Silver, Gold, Platinum and Titanium - that dictates their efficiency based on their rank.
