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.

Recommended PSU 450 W

Check Power supply size No PSU chosen. For an estimated 194 W peak draw, a 450 W unit leaves the ~40% headroom that covers transient spikes and keeps the PSU near its efficiency peak.
OK GPU power connectors No discrete graphics card, so no PCIe power connectors are needed.
OK Graphics card clearance No discrete card to fit.
Problem CPU cooler clearance A typical 80 mm cooler will not fit under this case's 70 mm panel.
Check Cooling capacity Adequate, but close. Expect the fans to be audible under sustained all-core load.
OK Motherboard fit This case accepts MINI-ITX boards.

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.
