600W PSUs

600W PSUs deliver power at maximum efficiency to your PC system. Make sure to check your system requirements though as PSUs work best when they are at 50% capacity, so you want to buy a PSU with twice as much capacity.

What is a 5001-600W PSU ideal for?

This wattage range of power supplies are perfect for systems that do not consume large amounts of power. For example, systems which are designed for word processing, internet browsing and general desktop work will benefit from a PSU in this range. 5001 to 600W will also be able to power a gaming PC which does not have a high-end graphics card.

What is a PSU?

Power Supply Units (PSUs) are frequently overlooked as part of a PC build. Central processing units (CPUs), graphics processing units (GPUs) and solid-state drives (SSDs) frequently are paid more attention, many experts believe that the PSU is the most important bit of hardware as a stable and high-quality supply of power can easily outlast other parts. And this power source can be used again in future builds.

Reliable supply

Yes, this innocuous box is responsible for delivering a stable and reliable power supply to all of the components inside your computer. It is vital, and without it, your PC would be pretty useless. But how do PSUs actually work? They convert general-purpose alternating current (AC) available from the mains, which is 230V in the UK, into low-voltage direct current (DC) power which is better for the hardware of your computer. PCs usually need either 3.3V, 5V or 12V. The converted DC power is then distributed to the various components inside your computer so that they can function effectively.

Browse our full range of Power Supply Units in wattages from 300W to over 900W. Buy your new PSU today and we could deliver it to you tomorrow (terms and conditions apply).
