Seasonic PSUs


Seasonic Prime GX-850 850W 80 PLUS Gold Modular Power Supply

Here at Overclockers UK, you can find premium Seasonic PSUs. These power supplies are well known for their outstanding performance and are used in a wide variety of tasks, from consumer to industrial applications. What’s more, Seasonic is so well regarded, that many other brands utilise them to manufacture their own PSUs. Seasonic power supplies feature outstanding efficiency, each receiving an 80 PLUS Bronze or better rating. Plus, they also boast a premium build quality, and utilise the latest innovations such as the Intel ATX 3.0 standard. Furthermore, you’re sure to find a Seasonic PSU to match your power requirements, as they come in ratings from 550W to 1600W, and in non-, semi-, and fully modular variants.


What Wattage of PSU Will I Need?

Every component in your gaming PC has an electrical requirement, typically measured in Watts (W). To figure out the power needed by a component you need to multiply the voltage (V) of a component by its current (A), so V x A = W. When you combine all your components together, you will have the total power necessary for your computer to operate. This can range anywhere from as little as 100W to over 1000W depending on your hardware.

Once you discover how much power is needed, we recommend you pick a PSU that is at least 20% more than your calculated wattage. By doing this you give yourself plenty of headroom. With extra capacity, you give yourself an upgrade path in the future. This allows you to change hardware for more powerful equivalents as they are released.

The second advantage is that it keeps your gaming PC safe from rogue power spikes. This has become especially prevalent with recent graphics cards, which can, at points, draw more than three times their normal requirements. By giving yourself extra headroom, the PSU can more comfortably handle a sudden increase, which helps to keep your power supply healthy. Power surges can damage your PSU, causing it to trigger one of its protection systems and shut down. In certain worse case scenarios, they can fail completely, which could also damage other components in your computer.
