PC build compatibility check

Pick your parts and the tool runs through six rules. For each one it tells you what it found and why. It is an aid, not a guarantee – the final word belongs to your board maker’s CPU and memory support lists.

Checked:

The form is evaluated as you go, after every change.

A Processor and motherboard
Stated in the board’s specification.
B Motherboard and case
C Graphics card and PSU
With front fans / radiator fitted.
Does the PSU have a native 12V-2×6 (12VHPWR) cable?

Check report

Fill in at least one section.

    This is not a compatibility guarantee. The tool only checks the rules listed below. Before buying, check the CPU support list and memory list (QVL) on the board maker’s website, the dimensions in the case manual, and the connectors in the PSU and graphics card manuals.

    How it calculates

    The tool evaluates six rules. Each is derived from manufacturers’ published information:

    1. Socket. The processor and the chipset must belong to the same socket (AM4, AM5, LGA1700, LGA1851). Which chipsets belong to which sockets is taken from AMD’s and Intel’s websites.
    2. Chipset support for the processor. For AM4 we use the compatibility table from AMD’s website, including the cases marked “Selective Beta BIOS update needed”. For AM5, AMD states that all boards with 600- and 800-series chipsets support all AM5 processors, although 600-series boards may need a BIOS update for Ryzen 8000/9000 processors. For Intel we only check the socket – check support for a specific processor on a specific board in its CPU support list.
    3. Memory type. AM4 = DDR4, AM5 and LGA1851 = DDR5 (according to the makers). LGA1700 processors support both; the board decides.
    4. Board form factor and case. An ATX case will usually also take the smaller microATX and Mini-ITX, and a microATX case also Mini-ITX. Not the other way round. Some cases have exceptions – check their specification.
    5. Graphics card length. We compare the dimensions you enter. With less than 10 mm of clearance we warn you – makers round their dimensions and cables need room.
    6. PSU connectors. We count the 8-pin cables needed for the adapter, or confirm a native 12V-2×6 cable. We do not assess the PSU’s wattage here – that is what the PSU calculator is for.

    The status of each rule is shown by text and by the shape of the icon (circle with a tick = fine, triangle = check, octagon with a cross = does not fit), not by colour alone.

    Everything is worked out in your browser. Nothing is sent anywhere and nothing is saved, not even in browser storage.
