SpecPicks Verdict

SpecPicks scored EVGA SuperNOVA 750 GM using a rating × review-volume × price-fit model applied to published specs and reviews across the power supplies category. EVGA's power supplies lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.
