PC Build Compatibility Checker
Checks PSU wattage against estimated system draw with a headroom band, PSU connectors against what your GPU needs, GPU length and cooler height against case clearance, and CPU socket against motherboard. Returns a pass, warn or fail for each check, with the reason.
These figures are class estimates, not manufacturer specifications. They are useful for sizing a build and catching obvious mismatches, but confirm the exact clearance and connector requirements against your specific parts before you buy.

How accurate are these numbers?
They are class estimates, not manufacturer specifications. They are reliable for sizing a build and for catching obvious mismatches, but the exact clearance and connector requirements vary between individual models. Always confirm against the spec sheet for your specific parts before buying.
