A power supply, or PSU, is the component that provides power to everything else inside your PC – and so it’s a crucial. Power supplies include a range of cables to plug into all of the standard components inside a computer. Some PSUs have modular cables, so you only need to fit the cables to you need, resulting in a neater build and better airflow inside the PC.

PSUs are also rated for efficiency, with a more efficient model consuming less power. The ratings go from Bronze to Silver, Gold, Platinum and Titanium.

These 1000W, 1200W, 1300W, 1500W & even 1600W PSUs provide unparalled power, making them ideal for high-end gaming PCs and professional workstations with a multiple graphics cards and CPUs.

Ideal for today's high-end cases, these fans rotate at a slower speed than standard fans but due to the increased surface area this ensures a larger volume of air is passed which in turn means a cooler quieter PC system.

These hydro-coolers allow anyone to water-cool their processor. They combine the pump, tubing, radiator and fans into a single, sealed unit that's simple to install and doesn't require maintenance or filling, and they're compatible with most Intel and AMD processors. Hydro-coolers provide superior cooling to a budget air-cooler, helping you reduce unwanted system noise and potentially enabling you to overclock the processor for added performance.

These particular hydro-coolers attach to a free 120 or 140mm fan mount in your case, and also require sufficient space to install the radiator.

Hydro-coolers provide superior cooling to a budget air-cooler, helping you reduce unwanted system noise and potentially enabling you to overclock the processor for added performance.

These large hydro-coolers require attachment to a pair of free 120 or 140mm fan mounts side by side in your case, and also require sufficient space to install the radiator.

It's worth thinking about a fan controller if you've fitted your machine with numerous cooling fans and third-party heatsinks. These are generally installed inside the front 5.25in bays of your case and are used to monitor temperatures and fan speeds - so you can speed fans up if your hardware's struggling or slow fans down to quieter speeds if you have the headroom. Basic models are affordable but have fewer features, and pricier products include high-end features such as touchscreens and Internet connectivity.

These full-size towers are designed for high-end systems. That means oodles of features, and flexible interiors that cater for premium components, including multiple large graphics cards, plenty of hard disks and SSDs and often lots of water-cooling gear too. Their lavish, eye-catching designs can include windows, LED lighting and front doors as well – they're sure to make an impact.

From compact units that fit in the tightest confines to larger towers that offer better CPU temperatures and reduced noise there is a broad range of air coolers to choose from. Given the diversity, the air coolers here have at least one thing in common - they are all compatible with Intel CPUs.

As always, check that your chosen cooler is compatible with your specific CPUs socket, that it won't interfere with other components on your motherboard like RAM or heatsinks and that it will fit inside your case.

These air coolers are the most compact around, and are ideal for systems where space is at a premium, such as with mini-ITX builds or Home-Theatre PCs (HTPCs). Given that these coolers prioritise small size over performance, most are not suitable for high-end, overclocked CPUs.

Ensure you check that your selected cooler offers the cooling performance necessary to cool your processor, and whilst most provide multi-socket support, as always, check that your motherboard socket is supported.
