power supplies psu for your desktop computer

upgrade your computer with a powerful but energy saving power supply

Gaming Laptops and Desktop PricesPower Supplies are essential bits of kit in powering your system from small mini-atx or media systems through to traditional desktop tower computers. Typically a 350w-450w will be more than enough to keep most systems running. If you are a heavy user with lots of drives, powerful graphics cards, video editing and latest tech you should replace at least like for like or go up, ~500w-750w etc. ATX Power Supplies are the most common.

Always choose a well known brand, cheaper units are just that cheap and will use cheaper components which typically fail more often, and cause more hanging, cutouts, or general sluggish system stability.
