Frequently asked questions
What's the single best upgrade for an ageing PC?
If it still runs from a hard drive, an SSD transforms it more than any other part, for less than a night out. After that, more RAM helps heavy multitaskers, and a fresh graphics card revives gaming machines.
How do I know a component will fit my system?
Check the socket, slot standard and physical clearance against your motherboard and case before ordering. Reviews and listing Q&As are full of people confirming fit with specific systems, which is often quicker than decoding spec tables.
Is it worth paying more for a power supply?
Yes, within reason. The PSU is the one part that can take everything else down with it. A well-reviewed unit from a reputable brand with the right wattage and efficiency rating is cheap insurance for the whole build.
