PSU Calculator

The estimate uses only published component power facts. It is not measured wall power and returns insufficient data when critical CPU/GPU power evidence is missing.

Component options Show items requiring manual verification Show incompatible options

Compatible candidates appear by default when evidence permits. Unknown/manual-check candidates are hidden until enabled; they are never counted as compatible. With no related selection, candidates have not been checked.

Compatibility

Automated checks need more evidence or show a conflict. Full compatibility is not proven; complete the applicable manual checks before buying.

Select at least two related components to run checks.

Estimated recommended PSU capacity

Insufficient verified power data.

Known load: Not available W. Missing: CPU, GPU, Motherboard, Memory, Storage, CPU cooler, Case.

This is a planning estimate, not measured wall power.

Upgrade checks

No rule-based upgrade warningThe current verified facts do not expose a compatibility-driven upgrade need. Performance recommendations require verified benchmark evidence.

Performance upgrade rankings require verified benchmark evidence and are intentionally not generated.

Check a replacement

Explore compatibility before changing a part. Candidates are catalog entries in alphabetical order, not ranked upgrade recommendations.

Allow this build to be shared

Nothing is shared automatically. Use the button for each contribution. You can turn this option off at any time.

What is shared?

Selected component references, current compatibility and power statuses, missing-evidence indicators, methodology version, tool name, a random submission ID and submission time. The server records current live revision references.

No name, email, account details or advertising identifiers are included. Our contribution tables do not store IP addresses or device fingerprints; ordinary infrastructure network logging is separate.
