Quality score
How we score →A power supply has no performance benchmark: every 650W unit delivers 650W. This scores how well built and how liveable the SuperNOVA 650 GA is, out of 100, from six published factors.
Better always scores higher, but the steps are uneven on purpose: Bronze to Gold is worth 11 of the 25 efficiency points, Gold to Titanium only 6. A factor we hold no value for scores zero rather than being skipped, so a unit we know little about never outranks a fully specified one. That does mean a zero can mean either poor or unknown, which is what the confidence figure above is for. Physical size scores nothing: ATX is a fit decision, not a quality one.

What the SuperNOVA 650 GA can power
Compare all GPUs →The graphics cards this 650W unit meets the system requirement for, ranked fastest first at 1440p, with the margin left over. The resolution follows the wattage, because a unit this size is bought for a card that will be run at 1440p. Headroom is measured against the card maker’s own whole-system recommendation, so 0 W means it meets that recommendation exactly rather than falling short.
