Power Supply Unit

The humble computer power supply unit (PSU) is very often overlooked when upgrading or building a PC. However, if the PSU is underpowered for all the components then this can lead to instability or crashes. Modern Graphics Cards especially can require quite a hefty power supply, so ensure you choose one which more than covers the wattage required of all of your components. Then to save on those costly energy bills it's worth going for an 80 Plus™ bronze rated unit.

The 80 Plus™ mark certifies products that have more than 80% energy efficiency at 20%, 50% and 100% of rated load and a power factor of 0.9 or greater at 100% load. Then if you want to keep your cabling tidy, a modular unit helps remove unnecessary clutter and leaves your case interior free and clear. With Novatech's extensive range of brands and our own Powerstation Black units, you'll find a PSU to suit your needs with us.

Choosing the right Power Supply for you

The wattage of your Power Supply is very important and will vary on what you are using your PC for. For example if you're running a beastly Gaming PC with a top of the range NVIDIA GeForce GTX 1070 Series Graphics Card, you'll probably wanting to be looking at an 700W+ PSU realistically to ensure smooth, uninterrupted gameplay.
