PSU comparison · EVGA vs Seasonic · 2014 vs 2017

Estimates only. These calculators use typical component specifications and rough rules of thumb. They are for planning and education, not purchase advice. Verify every number against your parts’ official datasheets before buying or building.
Why a static comparison: AI search can list each part's spec sheet, but it cannot lay the two side by side with a grounded pick guidance calibrated to your workload. That is what this page does — every number below comes from the vendor datasheet / TechPowerUp entry.
