PC Builder

The builder checks your selections as you make them. Every result explains itself, and where a specification is missing from our data it says so rather than assuming the parts fit.

What this checks

Processor socket against motherboard socket, and whether the board may need a firmware update first. Memory generation, module count against available slots, and whether the rated speed is actually supported. Motherboard form factor against what the case accepts. Graphics card length and cooler height against case clearance. Radiator size against case mounting positions. Power supply capacity, connectors, format and depth. Available M.2 slots and SATA ports. And whether the build can produce a display output at all, which catches the processor without integrated graphics and no card fitted.

What it cannot check

It cannot know the revision of the board that arrives in your box, so firmware advisories are warnings rather than verdicts. It cannot verify a dimension we do not hold, which is why graphics card length is frequently reported as unverified: partner cards using the same chip differ by more than 50 mm, and a reference figure would mislead. And it cannot tell you whether a part is good value, which is a judgement rather than a specification.

Our methodology page sets out how the rules work and where the data comes from.
