The power supply, or PSU, powers all the components inside your PC. The main thing you need to know when shopping is the approximate wattage your system will consume, so roughly tally up the power consumption of your various components. It is recommended to over-spec a little to ensure reliable operation, and get a little extra for future upgrades. Also check that the PSU comes with enough connections for your build, and that it will fit inside your chassis. Modular PSUs allow you to minimise excess cabling by only having the connections you need attached, meaning your PC will not only look more professional but will also run cooler.
These braided cables come for the range of power requirements that a computer power supply unit supplies. The braiding ensures a neat cabling solution to the internals of your computer which translates to less obstruction to the internal air flow for your hardware. These range of cables include motherboard, VGA cards, hard drive extension and adaptor cables plus mains cables.
This category includes emergency USB-based charging packs & cables for recharging your most important mobile devices and smartphonesat home or on the move.
A range of extension lead, adaptors and surge protection.
Fanless PSUs are ideal for low noise and silent computers – with heatsinks and good efficiency, they require no fan to stay cool, eliminating noise entirely. Although they have limited power compared to fan-cooled PUs they can be used in the vast majority of today's single GPU systems, and are available in modular and non-modular types.
The gold standard in PSUs, these power supplies have fully modular cables which means you need to connect the cables your PC needs, resulting in a less cluttered, cooler-running and better looking PC.
Hybrid modular PSUs tend to have only the most essential cables permanently attached to the PSU, while extra PCIe, SATA and Molex connectors are supplied as modular cables. They're usually cheaper than fully modular PSUs, and are a cost-effective way of achieving a clean and tidy build.
It's no good if your laptop's power supply has stopped working, or if it's been lost. Our selection includes third-party power packs that work with dozens of machines from top manufacturers, replacement batteries, emergency charging packs and even ruggedised chargers for working in demanding locations.
This category includes a selection of useful bits of hardware that, nevertheless, don't fit elsewhere on our site. We've got USB car chargers and power supplies intended for specific products.
This category includes emergency USB-based charging packs for recharging your most important mobile devices and smartphones on the move. Some are super small and discrete, ideal for your wallet or pocket, whilst over larger devices provide enough power to fully charge devices several times over.
Miscellaneous cables including keyboard, monitor and power cables.
These power supplies come in a range of small form factors like SFX, micro-ATX and TFX, which have reduced dimensions compared to standard ATX PSUs. Compact cases are sometimes designed with one of these form factors in mind – check that your PSU is compatible with your case.
These USB mains adaptors are ideal for powering or charging your favourite portable devices, such as handheld games consoles, mp3 players, and smartphones, via any UK mains power socket. We also have multi-port variants for charging multiple devices concurrently, along with a multi-region plug which is great for charging your devices in power sockets abroad.
These traditional PSUs (power supply units) have no detachable cables, making them less flexible than modular models when it comes to cable management, but they offer the best value for money. Look out for extra features too like high efficiency ratings, sleeved or flat cables, LED lighting and quiet fans.
