Corsair RM750e power supply

Quality score

How we score →

A power supply has no performance benchmark: every 750W unit delivers 750W. This scores how well built and how liveable the RM750e 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 RM750e can power

Compare all GPUs →

The graphics cards this 750W 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.
