What PSU should I buy for my PC Computer?

While many buyers select ATX supplies with the highest wattage, it's wise to narrow down your selection based on a power supply’s efficiency rating first. Look for units with an “80 Plus” certification - this means 80% of the PSU's rated wattage is supplied as power to the PC, while the remaining 20% is lost as heat. 80 Plus certification has different ratings within the standard, with 80 Plus Gold and Platinum being the most efficient PSUs available.

It's also worth knowing that a desktop system's components - not the power supply itself - dictate its power consumption. So a 1000W supply does not automatically use more power than an 850W power supply, instead depending upon the draw from a PC's hardware, peripherals, motherboard and CPU components under load.

Look also for a PSU with 20+4 pin connectors, meaning that its supply can function either as a 20-pin connector or a 24-pin connector. Larger cooling fans - for example a 135mm fan on an 850 Watt PSU - also move more air while delivering lower noise levels than cheaper, small fan equipped units.

Finally, look for modular power supplies. They offer an advantage over hard-wired versions in that you can add / remove cabling from the PSU to avoid cluttering your PC's internals.

Power supplies come in many forms, from regular batteries to large power bricks, so don't hesitate to get in touch with Tech Support if you need any assistance. You can reach them by calling 0800 294 4516.
